Data binding application program interface creation method based on XML mode

Abstract

In the view of complicated XML schema specifications existing in practice, an interface generation method for data binding application program based on XML mode, the invention, provides a method whichis used for automatically generating data binding API for XML files, the operation of which accords with XML Schema specifications. The method is characterized in that based on data binding technology, the method firstly generates a set of interlayer which is unrelated to the type of generated target language, and then type target code required by engine generation is generated by independent code. The text carries out code generation and test according to CNML Schema and CNML manuscript template issued by Xinhua News Agency. The result of experiments shows that the method not only ensures robustness and correctness of API, but also has great flexibility, greatly reduces API maintenance cost owning to change of the schema specifications, keeps basic consistency of multi-lingual API interfaces to reduce training cost and provides stable support for an application system based on API.

Description

technical field [0001] The invention belongs to the field of xml data binding or code automatic generation. Background technique [0002] Data binding technology provides a simple and direct method to efficiently use various unstructured data sources such as XML and Database in Java, C++ and other platform applications. Through data binding, the application program can ignore the constraints of factors such as the actual structure of the XML file and the structure of the storage table in the database to a certain extent, and directly use the bound code to access the data content. When reading and writing files, some special types of data (such as numbers and dates) can be converted into types that exist in the programming language instead of being kept in text form, which allows applications to use the data itself more conveniently and effectively. Instead of paying too much attention to the way it is stored and represented. [0003] At present, there are many technical pr...

AI Technical Summary

Problems solved by technology

But when the Schema document that needs data binding contains complex features (such as extensions, restrictions, substitution groups, etc.), most of the existing open source technologies cannot fully support it.

As far as the XMLBean project supported by the Apache Foundation is concerned, although it can support most complex Schema structures, when using XMLBean for data binding, there is currently no effective method to achieve operations such as adding and modifying methods for generating APIs , which makes XMLBean incapable of generating highly customizable APIs; in addition, XMLBean only supports the generation of APIs under the Java platform, which prevents many applications based on other platforms from being directly used
