Abstract

PROBLEM TO BE SOLVED: To provide a technology for correcting a value of an element in a structured document to a proper value with a more compact structure when the value is determined to be improper.SOLUTION: A data type comparator 118 compares a data type of an element in a structured document 142 with a data type in a data type definition table 116 to determine whether or not the data types are identical to each other. When the data types are not identical to each other, a data correction value acquisition section 120 acquires a corresponding correction value from a data correction value table 119. A data correction section 121 updates the data type of the element in the structured document 142 with the correction value acquired by the data correction value acquisition section 120.

Description

  The present invention relates to a technique for analyzing a structured document described in a language such as XML.

  Conventionally, a syntax analysis program called an XML parser is known as means for analyzing a structured document described in an XML language whose specifications are defined by the W3C. In addition, when parsing a structured document using an XML parser, a schema verification technique for verifying the validity of a document structure, data type, etc. is known in comparison with a schema definition described in an XML schema description language. ing.

  For example, Patent Document 1 describes a technique for simplifying the validity verification process and improving the processing speed. Typical examples of the XM schema description language include W3C standard XML Schema and ISO standard Relax NG.

JP 2003-84987 A

  In some cases, the application program performs validity verification by comparing the schema definition and the XML document while the XML document is being analyzed using the XML parser. As a result of the validity verification, when the XML document is different from the schema definition, the XML parser notifies an error message to the application program.

  When an error message is notified, there is no problem in the structure of the XML document, but if there is a problem in the character string or attribute value of the element contents, the application program corrects the error to an appropriate value and continues processing. Often there is.

  However, if the appropriate value differs depending on the execution environment or there is a possibility that it will be changed later in the same execution environment, add a process to dynamically acquire the correction value at the time of execution in the application program. There is a need.

  When there are a plurality of such application programs, it is necessary to add such processing for each application, and there is a problem that the total size of the application programs becomes large.

  The present invention has been made in view of the above problems, and in order to realize an operation for correcting an appropriate value when there is a problem in the value of a component in a structured document with a simpler configuration. Provide technology.

  In order to achieve the object of the present invention, for example, an information processing apparatus of the present invention comprises the following arrangement. That is, a means for acquiring a structured document to be analyzed, condition information set in advance as a condition to be satisfied by a value of a component in the structured document, and the value of the value when the value does not satisfy the condition A determination means for determining whether or not the value of the component satisfies the condition using table information in which a correction value set in advance as a value to be used in advance is registered, and the value of the component is When the determination unit determines that the condition is not satisfied, the modification value is acquired from the table information, and the structured document is updated by replacing the component value with the acquired correction value. Update means.

  According to the present invention, when there is a problem with the value of a component in a structured document, an operation for correcting this to an appropriate value can be realized with a simpler configuration.

  FIG. 2 shows a configuration example of the schema definition information 141. FIG. 2 shows a configuration example of the schema definition information 141 described in Relax NG, which is an XML schema description language defined by ISO. However, the namespace declaration unit 200 used for generating the data correction value list 119 and the attribute definition units 201, 202, 203, 204, and 205 for specifying the definition of the correction value are extended from the Relax NG specification.

  According to the schema definition based on the schema definition information 141 shown in FIG. 2, the structured document 142 to be analyzed (here, XML document) has a camera_setting element as a root element, and the root element includes name, pan, and tilt. Has a child element.

  The data type of the name element is a character string of up to 30 characters, and is used instead of the value of the name element if the data type of the name element in the structured document 142 is not "character string of up to 30 characters" The value (corrected value) is defined as “my camera”.

  The data type of the pan element is an integer value having a condition greater than −180 and less than or equal to 180. If the data type of the pan element in the structured document 142 is not “an integer value having a condition greater than −180 and 180 or less”, a value (corrected value) used instead of the value of the pan element is set to “− 179 ”and“ 180 ”.

  Further, the data type of the tilt element is an integer value having a condition of 0 or more and 90 or less. If the data type of the tilt element in the structured document 142 is not “an integer value having a condition of 0 or more and 90 or less”, a value (correction value) used instead of the value of the tilt element is “0”, It is defined as “90”.

  In the following description, the case where the information shown in FIG. 2 is used as the schema definition information 141 will be described. However, the essence of the following description is the same even if the element names, values, and conditions are different.

  FIG. 3 shows a configuration example of the structured document 142 described in the XML language. The value “−30” of the pan element in the structured document 142 illustrated in FIG. 3A is greater than the condition “−180 and 180 or less than the condition defined for the pan element in the schema definition information 141 illustrated in FIG. 2. It matches the integer value with the condition. Further, the value “60” of the tilt element in the structured document 142 shown in FIG. 3A is the condition “0 or more and 90 or less condition defined for the tilt element in the schema definition information 141 shown in FIG. Is an integer value with That is, the structured document 142 shown in FIG. 3A is a structured document that matches the schema definition by the schema definition information 141 shown in FIG.

  The value “−200” of the pan element in the structured document 142 shown in FIG. 3B is greater than the condition “−180 and 180 or less than the condition defined for the pan element in the schema definition information 141 shown in FIG. 2. It does not match “integer value with condition”. Further, the value “60” of the tilt element in the structured document 142 shown in FIG. 3B is the condition “0 or more and 90 or less condition defined for the tilt element in the schema definition information 141 shown in FIG. Is an integer value with That is, the structured document 142 shown in FIG. 3B is a structured document that does not match the schema definition by the schema definition information 141 shown in FIG.

  The value “minus thirty” of the pan element in the structured document 142 shown in FIG. 3C is the condition “-180 larger than 180 and less than 180 defined in the schema definition information 141 shown in FIG. It does not match the “integer value with the condition of”. Also, the tilt element value “60” in the structured document 142 shown in FIG. 3C is the condition “0 or more and 90 or less condition defined for the tilt element in the schema definition information 141 shown in FIG. Is an integer value with That is, the structured document 142 shown in FIG. 3C is a structured document that does not match the schema definition by the schema definition information 141 shown in FIG.

  Next, processing performed by the structured document analysis apparatus 100 will be described with reference to FIG. 7 showing a flowchart of the processing. The process according to the flowchart of FIG. 7 is started in response to the CPU 130 detecting an instruction to analyze the schema definition information 141. The analysis instruction for the schema definition information 141 is input via an application program loaded in the memory 110. This analysis instruction may be input using a user interface (not shown) (such as a keyboard or a mouse) provided in the structured document analysis apparatus 100. In any case, the analysis instruction is executed by the application program. Via the CPU 130.

  In step S <b> 701, the schema definition analysis unit 111 reads the schema definition information 141 from the storage device 140 into the memory 110. In step S702, the schema definition analysis unit 111 reads information defining the structure of the structured document from the read schema definition analysis unit 111, and writes the read information to the structure definition list 113, thereby defining the structure definition. The list 113 is completed.

  FIG. 4 shows a configuration example of the structure definition list 113 created in step S702 from the schema definition information 141 of FIG. In the element name column 401, the element name camera_settings of the root element defined in the schema definition information 141 and the element names name, pan, and tilt of the child elements are registered. These elements are “elements that the structured document 142 should have”. Also, in the structure information column 402, the rule “the child elements name, pan, and tilt are in this order” to be followed by the root element and the rule “the content defined by <data> as the element content” are to be followed by the child elements. "Has a character string of" is registered. These rules are “rules that the structured document 142 should follow”.

  Returning to FIG. 7, in step S703, the schema definition analysis unit 111 reads information defining the data type of the child element in the structured document from the schema definition information 141 read in step S701. Then, the schema definition analyzing unit 111 writes the read information in the data type definition list table 116 to complete the data type definition list table 116.

  FIG. 5 shows a configuration example of the data type definition list table 116 created in step S703 from the schema definition information 141 of FIG. In the element name column 501, element names name, pan, and tilt of child elements defined in the schema definition information 141 are registered. These elements are “elements that the structured document 142 should have”. In the data type information column 502, the data type of each child element is registered. For example, the element name “name” of the name element is registered in the column 501, and the data type “character string of up to 30 characters” of the name element is registered in the column 502. In this way, the element name and the data type of the child element having this element name are associated with each other and registered in the data type definition list table 116. Note that these data types are “data types that child elements in the structured document 142 should have”.

  In step S704, the schema definition analysis unit 111 determines that the data type of the child element in the structured document to be analyzed does not match the data type defined in the schema definition information 141 from the schema definition information 141 read in step S701. The correction value used in the case is read out. Then, the schema definition analyzing unit 111 completes the data correction value list 119 by writing the correction values read from the schema definition information 141 for each element in the data correction value list 119.

  FIG. 6 shows a configuration example of the data correction value list 119 created in step S704 from the schema definition information 141 of FIG. In the element name column 601, element names name, pan, and tilt of child elements defined in the schema definition information 141 are registered. These elements are “elements that the structured document 142 should have”. In the condition column 602, conditions that do not satisfy the conditions defined in the data type registered in the column 502 for each child element are registered.

  For example, in the case of the name element, since the data type of the name element is “a character string of 30 characters or less” from FIG. 5, the condition that does not satisfy the condition indicated by this data type is “greater than 30 characters”. However, the condition “greater than 30 characters” is written in the field 602 corresponding to the name element.

  In the case of the pan element, the data type of the pan element is “an integer value having a condition greater than −180 and less than or equal to 180” from FIG. 5, and therefore the condition that does not satisfy the condition indicated by this data type is “180 "Below" or "greater than 180". However, in the column 602, conditions corresponding to the pan element are described as “180 or less” and “greater than 180”.

  In the correction value column 603, a correction value used when the conditions described in the column 602 are satisfied is registered. For example, ““ my camera ”” is registered as a correction value at a location corresponding to the name element in the field 603. If the data type of the name element in the structured document 142 is “greater than 30 characters”, the value of the name element is replaced with this modified value “my camera”.

  In this way, by performing the processing of steps S701 to S704 described above, each table information (structure definition list 113, data type definition list 116, data correction value list 119) can be completed. Note that the description example of the schema definition information 141 in FIG. 2 shows an example in which the structured document does not include the attribute definition. However, even when the attribute definition is included, step S701 to step S701 are performed by replacing the element name with the attribute name. The same processing as S704 can be performed.

  Next, when the CPU 130 detects an analysis instruction for the structured document 142 input via the application program loaded in the memory 110, the processing in step S705 is started. In step S705, the structured document 142 is analyzed using the table information completed in the processing in steps S701 to S704, and the analysis result is notified to the application program instructed to analyze the structured document 142. The process in step S705 will be described using the flowchart of FIG. 8 showing details of the process in step S705. Note that the processing described below (steps S802 to S812 and steps S814 to S816) is performed for each node (document structural unit such as elements and attributes) included in the structured document 142.

  In step S <b> 802, the structured document analysis unit 112 reads a node (next node) that has not been read yet in the structured document 142 that has been read from the storage device 140 to the memory 110.

  In step S803, the structure definition acquisition unit 114 refers to the structure definition list 113, and the rules to be followed by the node name (element name) of the node read in step S802 (structure information registered in the column 402 in FIG. 4). Is read. For example, if the node read out in step S802 is the name element, in step S803, the rule corresponding to the name element “has a character string in the format defined by <data> as the element content” from the structure definition list 113. read out.

  In step S804, the structure definition comparison unit 115 compares the node structure of the node read in step S802 with the node structure indicated by the rule read in step S803, and determines whether or not they match each other. As a result of this determination, if it is determined that they match, the process proceeds to step S806 via step S805, and if it is determined that they do not match, the process proceeds to step S814 via step S805.

  For example, when the structured document 142 has the structure shown in FIG. 3A, the structure of the root element camera_settings in the structured document 142 includes the structure (child elements name, pan, and tilt shown by the structure information shown in FIG. Match in order). In this case, however, the process proceeds to step S806 via step S805.

  In step S814, the data notifying unit 122 indicates to the application program that has instructed the analysis of the structured document 142 that the structure of the structured document 142 does not match the structure defined by the schema definition information 141. To be notified. Thereafter, this process is terminated.

  On the other hand, in step S806, the data type definition acquisition unit 117 registers the data type (registered in the column 502 in FIG. 5) corresponding to the node name (element name) of the node read in step S802 from the data type definition list 116. Read data type information). For example, if the node read in step S802 is the name element, the data type “character string of up to 30 characters” is read from the data type definition list 116 in step S806.

  In step S807, the data type comparison unit 118 compares the data type of the node read in step S802 with the data type read in step S806, and determines whether or not they match each other. As a result of this determination, if it is determined that they match, the process proceeds to step S815 via step S808, and if it is determined that they do not match, the process proceeds to step S809 via step S808.

  For example, it is assumed that the structured document 142 has the structure shown in FIG. 3A and the node read in step S802 is a pan element. In this case, the value “−30” of the pan element matches the condition “integer value having a condition greater than −180 and 180 or less” defined for the pan element in the data type definition list 116. In this case, the process proceeds to step S815 via step S808.

  For example, assume that the structured document 142 has the structure shown in FIG. 3B and the node read in step S802 is a pan element. In this case, the value “−200” of the pan element in the structured document 142 matches the condition “integer value having a condition greater than −180 and 180 or less” defined for the pan element in the data type definition list 116. I have not done it. In this case, the process proceeds to step S809 via step S808.

  In step S815, the data notification unit 122 notifies the application program instructed to analyze the structured document 142 of the node value read in step S802. For example, when the structured document 142 has the structure shown in FIG. 3A and the node read in step S802 is a pan element, the value “−30” of the pan element is notified. If the node read out in step S802 is a tilt element, the tilt element value “60” is notified.

  On the other hand, in step S809, the data correction value acquisition unit 120 registers the correction value (registered in the column 603 in FIG. 6) corresponding to the node name (element name) of the node read in step S802 from the data correction value list 119. Read the correction value. At this time, the correction value corresponding to the condition satisfied by the node read in step S802 is read from the data correction value list 119.

  For example, assume that the structured document 142 has the structure shown in FIG. 3B and the node read in step S802 is a pan element. In this case, the value “−200” of the pan element corresponds to “−180 or less” out of the two conditions defined for the pan element in the data correction value list 119. In step S809, this value corresponds to this condition. The correction value “−179” to be read is read out.

  If the correction value corresponding to the condition is not registered in the data correction value list 119 (when the correction value cannot be read in step S809), the process proceeds to step S816 via step S810. . In step S816, the data notification unit 122 indicates to the application program that has instructed the analysis of the structured document 142 that the data type of the node does not match the data type defined by the schema definition information 141. To be notified.

  On the other hand, when the correction value corresponding to the condition is registered in the data correction value list 119 (when the correction value can be read in step S809), the process proceeds to step S811 via step S810.

  In step S811, the data correction unit 121 updates the node value read in step S802 with the correction value read by the data correction value acquisition unit 120. For example, assume that the structured document 142 has the structure shown in FIG. 3B and the node read in step S802 is a pan element. In this case, the value “−200” of the pan element is updated to the correction value “−179”. As a result, the structured document 142 is updated. Then, the data correction unit 121 transfers this correction value to the data notification unit 122. Note that the process of updating the value of the node read in step S802 is not essential and may be omitted.

  In step S812, the data notification unit 122 notifies the correction value received from the data correction unit 121 in step S811 to the application program instructed to analyze the structured document 142.

  When the structured document 142 has the structure shown in FIG. 3B, the following values are notified to the application program instructing the analysis of the structured document 142 by performing the processing according to the flowchart of FIG. Will be.

-"Camera0001" as name element value (as described in structured document 142)
-Pan element value "-179" (modified value)
-The value of the tilt element is "60" (as described in the structured document 142)
When the structured document 142 has the structure shown in FIG. 3C, the following values are given to the application program instructing the analysis of the structured document 142 by performing the processing according to the flowchart of FIG. You will be notified.

-"Camera0001" as name element value (as described in structured document 142)
-Data type mismatch error as pan element value-"60" as tilt element value (as described in structured document 142)
Accordingly, the application program that has instructed the analysis of the structured document 142 can receive a correction value when the data types do not match from the structured document analysis unit 112.

  The process according to the flowchart of FIG. 8 is basically based on the following process. In the process of FIG. 8, a correction value set in advance as a value to be used instead of the value of the component in the structured document to be analyzed, and a condition that this value should satisfy in order to use this correction value instead of this value Table information registered in advance as condition information is used.

  That is, first, using this table information, it is determined whether or not the value of this component satisfies this condition. When it is determined that the value of this component satisfies this condition, the correction value is acquired from the table information, and the value of the component is replaced with the acquired correction value. Update the document.

[Second Embodiment]
FIG. 9 shows a configuration example of the schema definition information 141 according to this embodiment. FIG. 9 shows a configuration example of the schema definition information 141 described in Relax NG, which is an XML schema description language defined by ISO. However, the namespace declaration part 200 used in the generation of the data correction value list 119, the definition part 901, 902 for designating the value that can be taken by the element and the correction value to be used when the value of this element matches this value, 903 is extended from the Relax NG specification.

  In FIG. 9, the values that the name element can take are “camera0001”, “camera0002”, and “camera0003”. If the value of the name element in the structured document to be analyzed is, for example, “camera0001”, the correction value to be used is “1”. If the value of the name element in the structured document to be analyzed is “camera0002”, the correction value to be used is “2”, and the value of the name element in the structured document to be analyzed is “camera0003”. If so, the correction value to be used is “3”.

  In the present embodiment, steps S701, S702, S704, and S705 are performed in the flowchart of FIG. However, the structured document analysis apparatus 100 according to the present embodiment does not require the data type definition list 116, the data type definition acquisition unit 117, and the data type comparison unit 118.

  The data correction value list 119 generated in step S704 has the configuration shown in FIG. In the element name column 1001, “name”, which is the element name of the name element collected from the schema definition information 141, is registered. Registered in the condition column 1002 are values that can be taken by the name element collected from the schema definition information 141 (actually, when this value is taken). In the column of the correction value 1003, for each condition registered in the column 1002, the correction value used when this condition is satisfied is registered.

  In this embodiment, in step S705, processing according to the flowchart shown in FIG. 11 is performed. In FIG. 11, the same processing steps as those in FIG. 7 are denoted by the same step numbers, and the description thereof is omitted.

  In step S1108, the data correction unit 121 determines whether the node value read in step S802 satisfies any condition (data type) in the column 1002 in the data correction value list 119. As a result of this determination, if none of the conditions is satisfied, the process proceeds to step S816. On the other hand, if the condition that the node value read in step S802 satisfies the condition in the column 1002 in the data correction value list 119, the process proceeds to step S1109.

  In step S1109, the data correction value acquisition unit 120 acquires a correction value corresponding to the condition that the node value read in step S802 satisfies from the column 1003 in the data correction value list 119.

  If there is no corresponding correction value, the process proceeds to step S815 via step S1110. On the other hand, if there is a corresponding correction value (when acquisition in step S1109 is successful), the process proceeds to step S1111 via step S1110. In step S <b> 1111, the data correction value acquisition unit 120 transfers the correction value acquired in step S <b> 1109 to the data notification unit 122.

  As described above, according to the present embodiment, when a structured document including a node (name element in this case) whose value that can be taken in advance by a schema definition is analyzed, the following can be performed. That is, it is possible to notify the application program of an alternative value, not the result itself (value of the name element) evaluated by the structured document analysis unit 112 at the time of data type verification. This eliminates the need to receive an evaluation result that is not required by the application program from the structured document analysis unit 112, particularly when the node value is large data such as the Base64 type.

  The processing according to the flowchart of FIG. 11 is basically based on the following processing. In the processing of FIG. 11, a setting value set in advance as a value that can be taken by the component in the structured document to be analyzed, and a value used instead of this value when the value of this component matches this setting value. Table information in which correction values set in advance are registered.

  That is, first, using this table information, it is determined whether or not the value of this component matches the set value. When it is determined that the value of this component matches the setting value, the setting value is acquired from the table information, and the value of the component is replaced with the acquired setting value. Update structured documents.

[Third Embodiment]
In the first embodiment, the structured document 142 is in the XML format. However, in this embodiment, the structured document 142 is in the EXI format, which is one of the binary XML formats standardized by W3C. explain.

  Even if the structured document 142 to be analyzed is in the EXI format, the structure of the structured document analysis apparatus 100 is the same as that of FIG. However, the first embodiment is different in that the data notification unit 122 notifies an application program of an analysis result or a correction value by an event such as AT (attribute) or CH (element content).

  In the EXI format, the grammar information generated from the schema definition information 141 by the schema definition analysis unit 111 is called a grammar. The grammar is grammatical information necessary for the structured document analysis unit 112 to analyze the structured document 142. Information of the structure definition list 113, the data type definition list 116, and the data correction value list 119 is included in the grammar. The rest is the same as in the first embodiment.

  According to each of the embodiments described above, a correct value can be acquired and processing can be continued without adding error recovery processing to an application program that has read an XML document whose data value does not match the schema. .

  Therefore, even when there are a plurality of application programs that perform XML document analysis that requires validity verification, the size of the application program can be reduced. A plurality of correction values can be specified according to the conditions at the time of analysis.

  Even when the correction value varies depending on the execution environment of the application program, it is not necessary to correct the application program itself by preparing a schema definition for each execution environment.

(Other examples)
The present invention can also be realized by executing the following processing. That is, software (program) that realizes the functions of the above-described embodiments is supplied to a system or apparatus via a network or various storage media, and a computer (or CPU, MPU, or the like) of the system or apparatus reads the program. It is a process to be executed.
