Embodiment
Often management is based on the electronic document of XML in client terminal/server structure, and this client terminal/server structure is stored in the document in the server, and according to user's request the electronic document of needs is provided.This client terminal/server structure is as shown in Figure 1.
Fig. 1 is the synoptic diagram of asking/providing the client terminal/server structure of common electronic document based on XML.As shown in Figure 1, this client is a document requester/user side, and server is the document provider.Therefore, if the system of request and use document has the function of storing simultaneously and the document being provided, client and server can serve as simultaneously according to its role in this system.
The language of searching for these XML documents comprises XML query language (XQL) and XQuery.These search languages are widely used in the XML document that search is stored in the electronic document repository of server, and the form of the XML document that needs with the requestor provides the result.
For example, below XQL will be described.This XQL is the device that is used for searching for and be chosen in the position of data field that XML document exists and text.This XML file is used for that transmit data set closes between the computing machine on the network.This XQL is provided for searching for or selecting in the data acquisition in the XML file instrument of specific project.But this is based on the format syntax of using in the expansion design language (XSL).Extended version as XSL proposes this XQL.
In order to handle, this XSL form language uses simple catalogue symbol with expression specific factor title.For example, " books/author " expression " at specific context, such as all the author's compositions in all books compositions of search in the XML document ".This XQL will use Boolean logic, and the performance of selection component and the set of index composition is added to the catalogue format symbol.This XQL might produce the program of the electronic document repository that can search for storing X ML file, and the hyperlink that is linked to special component is provided.
As stated,, ask the user of this electronic document should learn other search languages, and specify the structure that is used as the XML document that Search Results provides using these search languages to ask to provide in the art methods of electronic document.Therefore, for hope request and the user who receives based on the electronic document of preassigned Grammer creation, the XQL method of prior art is invalid.
With the preferred embodiment that describe to use prescriptive grammar according to the invention based on the electronic document request method of XML.Electronic document based on XML can use DTD (DTD) or XML pattern language to define grammer.These syntactic definitions entire electronic document structure and constraint name and each key element occurrence frequency, in proper order, it is required key element or optional key element, the attribute of each key element etc.This electronic document becomes effective document with respect to the grammer that is provided by these language.
The preferred embodiments of the present invention can constitute the request document of request information needed through using prescriptive grammar, and can the information from electronic document repository be provided through using the request document request.In other words, the requestor asks information is offered electronic document repository through request document or similar document that transmission has the information needed that writes down based on prescriptive grammar.
Preferably, the request document of formation only has element name/attribute name, and does not have the detailed information values based on the element name/attribute name of grammer.In addition, if there is the information to limit the information that will be provided, can be stored in together in the request document with identifier or based on the element name/attribute name and the particular value of grammer.
Therefore,, the requestor gives electronic document repository when sending the request document, when electronic document being provided with request, and can be not in accordance with the required key element in the restriction of prescriptive grammar or the grammer of required attribute.In other words, because after key element that insertion only needs or property value, electronic document is provided,, can omit required key element or required attribute if there is not the required value of information to the data bank request.
In the information of indicating to provide and have an element name/attribute name of the identifier value or the particular value that are used for limiting this information, the electronic document described of the hierarchical structure of grammer is preferably as the request document according to the rules.Available electronic document comprises the value of required element name/attribute name, and satisfies the element name/attribute name as discre value or condition.
In other words; According to the electronic document request based on XML of the present invention/provide method; Ask to provide electronic document through using the request document with corresponding message; In this request document, the hierarchical structure of grammer is described the discre value of the electronic document that will ask and the key element that will provide according to the rules.
In addition, according to the electronic document request based on the XML of the present invention/embodiment of method is provided,, add the invalid of content that property value deleted with notice the provider if the content of the document that provides is deleted or no longer valid.And, according to the electronic document request based on the XML of the present invention/embodiment of method is provided,, preferably be inserted in the key element title and notify the document invalid through the content that only will delete if the predetermined content of the document that provides is deleted or no longer valid.
For example, can be applicable to ask to provide the requestor of electronic document, supplier and dispose connection request person and supplier's the system of network of the electronic document of request is provided according to the embodiment of the electronic document request based on XML of the present invention/provide method.And this electronic document request/provide method to can be used for a kind of system, this system only provide such as broadcast program the essential information under the environment of system are provided, and receive additional information according to user's request through network.
For example, can be like the grammer of the electronic document of the broadcast program of giving a definition, and will electronic document request/provide method be described with reference to accompanying drawing 2.Fig. 2 shows by the synoptic diagram of establishment based on the syntactic structure of the broadcast program of the art methods generation of the electronic document of XML.
As shown in Figure 2; Suppose that broadcast program has the program identifier of title and unique this program of indication (ID) information; Such as the information of broadcasting service, time and duration about broadcasting, and such as the information about content of plot summary, comment and cast.At this, with describing the situation that title, program identifier, time and duration are defined as required key element.Therefore, as shown in Figure 2, solid line is represented required key element, and dotted line is represented optional key element.
Shown in Fig. 3 and 4, can use DTD and XML pattern to describe these programs.Fig. 3 is the synoptic diagram of DTD that shows the grammer of the broadcast program that is produced by the art methods of creating based on the electronic document of XML, and Fig. 4 is the XML pattern diagram that shows the grammer of the broadcast program that is produced by the art methods of creating based on the electronic document of XML.
DTD is an Application of XML, so that mark particular document type, and by its rule that should be used for confirming.The definition of Doctype can comprise the key element type by marker expression, and element relationship and attribute are with the rule of relevant benchmark.
In Fig. 5 and 6, shown in fact broadcast program based on Grammer creation.Fig. 5 and 6 is by the synoptic diagram of establishment based on the broadcast program electronic document of the art methods establishment of the electronic document of XML.At this, all comprising is the title of required key element, but can not comprise optional key element.
Fig. 7 shows that request provides the view by the request document synoptic diagram of the electronic document of creating according to the electronic document request method based on XML of the embodiment of the invention.Suppose the comment of requestor to broadcasting station request specific program.At this moment, this requestor can create request document as shown in Figure 7.
As shown in Figure 7, this request document can use the same syntax of figs of Fig. 5 and 6.Although the present invention is not intended to restriction.Yet omission is the title key element of required key element, and after " identifier " key element of inserting required programs and " comment " key element, to the data bank request electronic document is provided.
Therefore, the user's through producing request document shown in Figure 7 etc. request can offer electronic document repository with the request document.Fig. 8 is the block diagram of the electronic document synoptic diagram of the request that shows that the request document according to Fig. 7 provides.And as shown in Figure 8, grammer according to the rules can offer the electronic document application system that the user uses with the electronic document that comprises solicited message.
As further for example, suppose the program of requester requests by certain actor or actress's performance.At this moment, this requestor can create request document as shown in Figure 9.As shown in Figure 9, this request document can use the same syntax of figs of Fig. 5 and 6.Yet omission is the title key element of required key element, and after only inserting " cast " key element of required programs, to the data bank request electronic document is provided.At this because title key element and be required key element about the information of " broadcasting ", even in asking document, do not have mark they, also these information should be provided automatically.
Therefore, shown in figure 10, response user's request, this electronic document repository grammer according to the rules provides the electronic document that comprises information requested to the electronic document application system that the user uses.
According to the electronic document request based on XML of the present invention/provide method, the requestor can ask to provide the electronic document that is stored in electronic document repository through using prescriptive grammar (for example, not learning to be used for the grammer of other language of searching request).In addition, because through only using the system that handles prescriptive grammar based on XML to handle the electronic document that provides from electronic document repository, embodiment that therefore can more effective execution the inventive method.
Simultaneously, for the grammer of the definition electronic document structure of being constructed, in required/optional key element and/or required/optional attribute, the element name/attribute name of record request document optionally.The element name/attribute name of selectivity record can represent to be provided for the element name/attribute name of the information of the electronic document that will be provided in the request document.And if corresponding value is recorded in the element/attribute of selectivity record in the request document, the record value of element name/attribute name representes to respond the condition that electronic document that the user asks to be provided should satisfy element name/attribute name.
And, if there is the content that will delete owing to the variation of document content, for example,, can carry out like Figure 11 and/or process shown in Figure 12 if cancel prearranged broadcast program.In other words, like Figure 11 and shown in Figure 12, for example through adding invalid or being waited the cancellation of notifying prearranged broadcast program by deletion key element title or Property Name.
Figure 11 shows that the electronic document based on XML according to the present invention provides the embodiment of method, through provide to document notice the document invalid the view about the synoptic diagram of the embodiment of the information of deletion document will usually be provided.Figure 12 is another embodiment that the electronic document based on XML according to the present invention provides method, through notice the document invalid attribute is provided to document the synoptic diagram about the information of the document deleted is provided.
Say that in more detail through adding invalid element, can provide about prearranged broadcast program, for example the information of the cancellation of " Larry King " is shown in figure 11.Simultaneously, through discerning the identifier of the document, can confirm the content that will be deleted that comprises as the invalid content in the document that provides.If the content of identifier element as invalid element is provided, the corresponding entire document of deletion from the storage of client.If comprise can discern the respective document in the document that provides identifier (for example; Identifier element) and only the content that will delete that comprises respective document is as the invalid element title, and the corresponding contents that only in the invalid element title, comprises is preferably deleted from the storage of client.
And, can be simply the broadcast program about stipulating be provided, the information of the cancellation of " Larry King, " for example, model shown in figure 12 through adding Property Name < program invalid=" very " >.Simultaneously, notifying the invalid Property Name of the document that provides can be the attribute that can discern the identifier element title of the document that will delete.Under the situation of the Property Name that the attribute that notification identifier key element title is provided becomes invalid, deletion can be by the entire document of the correspondence of corresponding document identifier identification from the storage of client.
In addition; If comprise the identifier that to discern the respective document in the document that is provided; And when invalid attribute is notified in the conduct of the content that will be deleted of the respective document that only provides to some extent, only preferably from the storage of client, deleted by the corresponding contents in the document identifier documents identified.
Electronic document based on XML according to the present invention provides the embodiment of method; It is that deleted through deletion or because the variation of document content causes the content of no longer valid can upgrade the document gradually; And the document need not be provided again, or through only providing invalid content to come to upgrade gradually the document.
As stated, be used for document request and/or the preferred embodiment of the method that provides has various advantages.According to a preferred embodiment of the invention, use the grammer predesignate, the electronic document based on XML can effectively be provided, and need not learn to ask the grammer of other language of electronic document.And the electronic document application system that the requestor uses can ask to search for electronic document, and the device and/or the algorithm that only are used for handling prescriptive grammar are handled the electronic document that provides from electronic document repository.In addition, if some of the document that provides or whole contents are deleted or become invalid, the content that can delete through notice simply reduces or prevents to use not have
Imitate document or its content.
The foregoing description and advantage only are demonstrations and do not constitute the restriction to invention.The content that the present invention instructed can easily be applied to the device of other types.The description of this invention is in order to illustrate, and does not limit the scope of claim.Many replacements, modification and variation are apparent to those skilled in the art.In this claim, the clause of device+function is in order to cover the structure of the function that execution described herein enumerates, to be not only the equivalence of structure, and is the structure of equivalence.
