Parsing method of xml file common parser based on Xpath language

Abstract

The invention discloses a parsing method of an xml file common parser based on an Xpath language, and relates to the technical field of java serialization and deserialization. The method comprises thefollowing steps of obtaining an identification result through an AI interface; calling the xml file common parser to introduce an identification result, XPath sentences for sifting data and businesstemplate objects; using the XPath sentences to directly filter node trees; conducting xml language deserialization, and using the xml file common parser to convert the Xml language into a java business object; completing data encapsulation and making the operation return to a business entity object. After the Xpath is adopted, nodes can be flexibly subjected to condition query like sql sentences,so that the code expansion is higher. The Xpath is combined with a Dom4j technology. The parsing method has the advantages that the code coupling degree is lowered, the code reusability is improved, and the business change can be better adapted to.

Description

technical field [0001] The present invention relates to the technical field of java serialization and deserialization, and more specifically, the embodiment of the present invention relates to a parsing method of a universal parser for xml files based on XPath language. Background technique [0002] Existing parsing techniques usually load DOM information into memory first, and then analyze the DOM structure. Analyzing the structure usually requires loading the entire document and constructing the hierarchy before doing any work. Since it is based on the information hierarchy, DOM is considered to be based on tree or object based. DOM-related operations can only be performed after the tree structure encapsulation is completed. On the other hand, for particularly large documents, parsing and loading the entire document may be slow and resource-intensive, and common techniques cannot flexibly handle the filtering of nodes in the DOM, and only provide simple retrieval function...

Problems solved by technology

[0007] During this period, the xml template and the Java object template are in a corresponding relationship. The change of the xml template can cause the codes of processes (1) and (2) to be modified accordingly. The code coupling is high, and the code may need to be continuously maintained as the business changes.

[0008] Existing parsers can complete the deserialization process of xml language, but as business changes need to filter useless data to reduce data transmission volume and business complexity, it is difficult for existing technologies to achieve
