Description
Technical field
The present invention relates to the display of XBRL instance document, a kind of particularly method realizing the preview of XBRL instance document based on dom4j.
Background technology
Extensible Business Reporting Language is based on internet, cross-platform operation, the computerese be specifically designed to financial report establishment, disclosing and use.Substantially realize the integrated of data and maximum using, accounting information exports one, resources sharing, is accounting standard combined with computerese in the world, for unstructured data, and the up-to-date recognised standard of especially financial information exchange and technology.By specifically identifying data are unified and classify, directly by user or other software are read and processes further, a typing can be realized, repeatedly uses.
In the instance document link of XBRL technical system, system adopts B/S (browser Browser/ server S erver) structure, because the instance data of instance document is stored in server end, user needs to use browser check and edit instance document, therefore, need to convert server end instance document example information to front end browser by certain mode can identify and the data structure shown.
Summary of the invention
The object of this invention is to provide a kind of front end browser that server end instance document information converted to can identify and the method for the data structure shown.Particularly, the invention provides a kind of method realizing the preview of XBRL instance document based on dom4j, the method comprises the steps:
A. created out in instance document by XBRL engine that certain needs preview role instance;
B. xStream instrument is used the complicated Java object model simplification of above-mentioned example to be become the relatively simple Java object of structure;
C. use dom4j by simplify after Java object conversion encapsulation formed instance document preview time front end need data structure;
D. front end flex carries out resolving and showing according to the instance document structure after dom4j conversion.
Particularly, in step C, the preview structure that described instance document front end needs is XML format file.
Further, also comprise before steps A, generate instance document example and instance document is stored in MongoDB database.
Particularly, the concrete grammar be stored into by instance document example in MongoDB database is: put in storage according to data set organization by same rights management relational database by configurable timed sequence, and carry out data set incremental update according to configuration frequency.
Particularly, when needs increase true value or increase footnote to instance document, by the MongoDB API that is correlated with, the instance document example information of preservation is read in whole or in part, again it is upgraded after modifying.
Particularly, give the correct time on needs establishment instance document file carries out, by the relevant API of MongoDB by complete for instance document example reading, construct instance document memory model by XBRL engine server, this memory model creates out the instance document file reporting needs
The invention has the beneficial effects as follows: this provides a kind of front end browser that converted to by instance document can identify and the data structure shown, because Instance Document data model is complicated, quantity of information is huge, change loaded down with trivial details, therefore by dom4j instrument, instance document is converted to the data structure of front end display, dom4j is the kit of specialized operations Java object and XML file, excellent performance, flexible and convenient to use, front end adopts flex technology to show, flex shows tree construction and tableau format bottom is all based on XML file, dom4j and flex with the use of, the perfect transition from Java object to front end browser display can be reached, and performance is in tolerance interval, specific performance must rely on data volume size, processing time and data volume linear.
Embodiment below in conjunction with embodiment is described in further detail technical scheme of the present invention; should be noted that; embodiment is only used to help reader better to understand technical conceive of the present invention, not in order to limit the protection domain of the claims in the present invention.
Embodiment
The invention provides a kind of front end browser that server end instance document information converted to can identify and the method for the data structure shown.Particularly, the invention provides a kind of method realizing the preview of XBRL instance document based on dom4j, the method comprises the steps.First, created out in instance document by XBRL engine that certain needs the role instance of preview.Secondly, xStream instrument is used the complicated Java object model simplification of above-mentioned preview example to be become the relatively simple Java object of structure.Then, dom4j is used the Java object conversion encapsulation after simplification to be formed the instance document structure of front end preview needs.Finally, front end flex carries out resolving and showing according to the instance document structure after conversion.
Embodiment
Below exemplary description is done to technical scheme of the present invention.
This provides a kind of front end browser that converted to by instance document can identify and the data structure shown, because Instance Document data model is complicated, quantity of information is huge, change loaded down with trivial details, therefore by dom4j instrument, instance document is converted to the data structure of front end display, dom4j is the kit of specialized operations Java object and XML file, excellent performance, flexible and convenient to use, front end adopts flex technology to show, flex shows tree construction and tableau format bottom is all based on XML file, dom4j and flex with the use of, the perfect transition from Java object to front end browser display can be reached, and performance is in tolerance interval.Comprise the following steps:
1, created out in instance document by XBRL engine that certain needs the role instance of preview;
2, xStream instrument is used the model simplification of the Java object complexity of described preview example to be become the relatively simple Java object of structure;
3, use dom4j by simplify after Java object conversion encapsulation formed instance document preview time front end need data structure; The preview structure that instance document front end needs is XML format file.
4, front end flex to resolve instance document according to the XML format file after conversion and shows.
Before the role's preview example creating instance document, need first to generate instance document, be stored in MongoDB database in the present invention by the instance document of generation, carry out accessing operation to facilitate, its concrete grammar is as follows:
1, instance document example is created out by XBRL engine server.
2, by some communication protocols, instance document example is transferred to instance document processing server.
3, the memory instance of instance document is persisted to mongoDB database by the mongoDB API that is correlated with by instance document processing server.
