Abstract

<P>PROBLEM TO BE SOLVED: To solve the problem with structured documents capable of describing links wherein there is the possibility that some of the links may not be necessary to the documents, in view of the fact that a document group consisting of a plurality of such structured documents, which are often bundled together and handled as one document, requires the links to be traced starting from the first document of the group during such processes as sending, receiving and printing the group. <P>SOLUTION: In the first document of a document group consisting of a plurality of documents, a list of documents included in the document group is stored so as to prevent processing of unnecessary documents during such a process as printing and to prevent the failure to process necessary documents, so as to achieve efficient processing. <P>COPYRIGHT: (C)2006,JPO&NCIPI

Description

  The present invention relates to an information processing apparatus.

HTML (Hyper Text Markup Language: http://www.w3.org/Markup/), which is used as a description language for websites, and XML (Extensible Markup Language: http: //), which has been widely used as a general-purpose data description language in recent years. In structured documents such as: //www.w3.org/XML/), link description methods for referring to other files and data are often prepared. For example, in HTML, an image file can be used as a part of display by using an img element, and a hyperlink function to another file can be realized by using an a element. In the future, with the spread of XML, SVG, etc., a lot of data will be processed in the form of structured documents. In many cases, such a structured document is not a single file, but is formed as a single document by using a plurality of files as a whole. Therefore, when processing such a structured document as storage or printing, it is necessary to process a plurality of files together. Therefore, HTML has a Link tag that clearly indicates what the designated document has. An example of using the HTML Link tag is shown in FIG. The first document 1101 (index.html) is described as <link rel = “next” href = “chap1.html”>, and the next document after this first document is 1102 (chap1.html). Indicates that there is. Similarly, 1102 (chap1.html), 1103 (chap2.html), and 1104 (chap3.html) also have Link tags, and the attributes of next, prev, and index are used for the next document, the previous document, and the first document, respectively. Represents. In the case of such a structure, the entire document can be traced by following the next document (see, for example, [Patent Document 1]).

  In the conventional structured document format, when data is transmitted and received between devices such as printing, storing, and data transfer, it is necessary to perform operations for each file. There is a way to follow the link destination, but it may process less important data. In HTML Link tag technology, it is necessary to trace one document at a time in order to know the structure of the entire document. Therefore, when the number of documents is large or when the documents are in other devices on the network, it takes a very long time. There is a problem that it takes time and effort.

  The structured document processing apparatus according to the present invention is for achieving the above-described object, and is configured to embed, in the first page, link destinations to be collectively processed in the structured document. In the structured document processing apparatus configured as described above, a list of documents to be processed is stored at the beginning of the structured document, so that data to be processed among the data associated with the structured document is likely to be processed. Since those that are not can be clearly distinguished, unnecessary documents will not be processed or necessary documents will not be missed. In addition, since it is included in the first page, link destination list information remains even after the document is exchanged, and an accurate process can be performed after the document is delivered.

  As described above, according to the present invention, the scope of a structured document consisting of a plurality of files is clarified by a link, so that the process of storage, printing, etc., and transmission / reception with other devices are intended by the producer. It is possible to perform as usual and without waste.

(Embodiment 1)
FIG. 1 is a diagram showing a first embodiment in which the present invention is applied to a computer apparatus composed of a personal computer or the like. In this embodiment, when printing a structured document on a network, only predetermined data is printed, so that necessary documents are not leaked and unnecessary documents are excluded. .

  In FIG. 1, a computer device 101 that creates a structured document, a file server 103 that stores a structured document created by the computer device 101, and a computer device 104 that browses a structured document stored in the file server 103. A printer 105 for the computer device 104 to print a structured document is connected by a LAN 102.

  FIG. 2 is a block diagram showing the configuration of the computer apparatus 101 according to the present invention. In the figure, a CPU 201 is a system control unit and controls the entire apparatus. The ROM 202 stores CPU control programs and various fixed data. The RAM 203 is composed of SRAM, DRAM, and the like, and stores program control variables and the like. Various setting parameters and various work buffers are also stored in the RAM 203. The storage unit 204 is composed of a hard disk or the like, and is for storing file data. The operation unit 205 includes a keyboard, a mouse, and the like, and is used by the operator to perform various input operations. The display unit 206 is used to notify the operator of the display using a display or the like. A LAN i / f 207 is an interface for connecting to the LAN line 208.

  FIG. 3 is a conceptual diagram of a structured document created by the computer apparatus 101. 301 (index.html) <a href = ”“ about. html ”>, <a href =“ manual. “mid”> and <a href=“reference”> indicate that they are linked to files 302 (about.html), 304 (manual.html), and 306 (reference.html), respectively. (EMBED SRC = “bgm. mp3> is bgm. <img src = “sample.jpg”> in 304 (manual.html) is sample.mp3. jpg indicates that each is linked. In FIG. 3, a plurality of objects such as an HTML file, an image, and an audio file are associated by a character string in the document. Here, the link is set by a character string, but it is also possible to set a link to an image or the like. Here, the link destination is a single file, but it is also possible to indicate only a part of the file.

  Also, in FIG. 3, the index. Two types of related document lists created by the producer are written in html. The first <collection> element has an index. html, about. html, manual. Only html is marked. This is because the producers only treated the text as an overview of this document. The second <collection> element has a reference. All files except html are listed. This is what the producer has written to handle everything that this document needs. Also, reference. This is because html has been linked from this document, but the producer has determined that it is not important to this document.

  The procedure for creating the related document list will be described with reference to the flowchart shown in FIG. The producer designates the conditions to be included in the related document list in the related document group in advance (S901). In the present invention, the term “related document group” is a set of documents having a tree structure obtained by unconditionally following links of structured documents. As a condition to be included in the related document list, specify by the number of layers, determine by file type or extension, include in the related document list if the link description is a relative path, and exclude the one described in the absolute path A method of excluding only a file having a large file size can be considered.

  Next, the first document is read (S902), and the read structured document is analyzed (S903). If there is a description of a link that has not been traced in the document that is currently being read (S904), it is determined whether the linked document meets the conditions to be included in the related document list (S905). If it doesn't meet the requirements, check the document you are reading for a link description you have never followed. If the condition is met, in addition to the related document list (S906), the link destination is read (S907), and the document further linked from the document is examined. If there is no description of a link that has not been traced to the document currently being read, if the currently read document is not the first document (S908), the process returns to the link source linking the current document (S909). If the currently read document is the first document (S908), and if there is a document to be manually included in or excluded from the related document list (S910), the manual operation is performed (S911). If not, the process ends. .

  Through the processes from S901 to S909, all the documents that should be automatically included in the related document list can be added from the structured document group having a tree structure. Through the processes of S910 and S911, the conditions included in the related document list can be included or excluded as exceptions.

  In the present embodiment, an automatic method and a manual method are combined, but it is possible to completely automate or manually.

  Assume that the computer apparatus 101 stores the document in FIG. 3 in the file server 103. The configuration of this file server is shown in FIG.

  In the figure, a CPU 401 is a system control unit and controls the entire apparatus. The ROM 402 stores a CPU control program and various fixed data. The RAM 403 is composed of SRAM, DRAM, and the like, and stores program control variables and the like. Various setting parameters and various work buffers are also stored in the RAM 403. The storage unit 404 is composed of a hard disk or the like, and stores file data such as documents and images. The operation panel 405 includes a keyboard, a touch panel, and the like, and is used by an operator to perform various input operations. The display unit 406 is used to notify the operator of display using an LCD, LED, or the like. A LAN i / f 407 is an interface for connecting to a LAN line 408.

  Next, a procedure for the computer device 104 to print the document in FIG. 3 will be described. The computer apparatus 102 sends an index.index, which is the top page of this document, from the file server 103. Read html and determine whether there is a related document list. In this example, each <Object> element in the <collection> element is a link destination. Therefore, when the “print” menu is selected, a menu as shown in FIG. 5 is displayed. At this time, if the target file already exists, or if the target file information is present, information such as the number of pages can be displayed at this stage. When “link list (abstract)” is selected, only 301 (index.html), 302 (about.html), and 304 (manual.html) are read and transmitted to the printer 105. If “what is in the related document list (detail)” is selected, all documents other than 304 (reference.html) are read and transmitted to the printer 105. Then, the printer 105 prints the received object, and printing is completed. If there is no list of link destinations, the process is as usual.

  Here, the computer device 104 reads out the objects included in the link destination list, but it is also possible to send only the top page to the printer 105 and the printer 105 reads out the objects in the link destination list.

  FIG. 8 is a schematic configuration diagram of a structured document processing system to which another embodiment of the present invention is applied. In the present embodiment, when a document including a relative link and an absolute link is transmitted to another device, the link information is appropriately converted.

  In this system, a computer apparatus 804 and file servers 801 and 802 are connected via a network 803. The configurations of the computer device and the file server are the same as those in the above configuration example.

  The file server 801 stores the structured document shown in FIG. Of the files linked from this document, 703 (pic.jpg) is not included in the linked list, and 704 (doc.html) is included in the related document list, but another file server 802 is included. (Bar.org). The file server storing the first document is 801 (foo.com).

  Here, the document in FIG. 8 is transmitted from the file server 801 to the computer device 804. At that time, if a file in the related document list is transferred as it is, when reading the document from the computer device 804, a link is not followed or an unnecessary file is received. I need it.

  The procedure for converting the link description will be described with reference to the flowchart shown in FIG. First, the first document is received (S1001), and if there is no related document list, the process ends (S1002). If there is, the window shown in FIG. 6 is displayed and the processing range is input (S1003). If there is only the first page, the process ends. When including the files in the related document list, all the files included in the related document list are received (S1004), the first document is read (S1005), and the structure of the document is analyzed (S1006). If there is a description of a link that has not been traced to the currently read document (S1007), it is confirmed whether the link destination is included in the related document list (S1008). If it is included, it is confirmed whether the description of the link is an absolute path (S1009), and if it is an absolute path, the description is converted to a relative path (S1010), and the linked document is read (S1010). S1011). If the linked document is not included in the related document list, it is checked whether the description is a relative path (S1012). If the link destination document is a relative path, the link description is converted to an absolute path (S1013). If there is no description of the link that has never been traced in the currently read document, it is confirmed whether the currently read document is the first document (S1014). If it is not the first document, the process returns to the link source, and the description of the link that has not been followed is checked. If it is the first document, the process is terminated.

  In this embodiment, the computer apparatus 804 sets <a xlink:href=“pic.jpg”> of 702 (FIG. SVG) to <a xlink: href = http: // foo. com / pic. jpg>, 701 (top.xml) <a href = http: // bar. org / doc. Replace html> with <a href=“doc.html”>.

  In this embodiment, the receiver converts the link description, but the sender can also perform the conversion.

  By appropriately converting the link description in this way, it is possible to accurately refer to the link destination even after the document is transferred to another device, and to browse the document without unnecessary reception.
