Problems solved by technology

[0007] First of all, the converted document model object needs to occupy memory, and the larger the XML data, the more memory it takes up, and there is a risk of memory overflow; secondly, in the case of relatively large XML data, using the above parsing method will make the parsing performance worse time-consuming will increase exponentially; finally, custom development conversion procedures need to consume valuable human resources, and the quality of development cannot be fully guaranteed

Embodiment Construction

[0061] In order to solve the problems existing in the prior art, an embodiment of the present invention provides a solution for parsing XML data. In this technical solution, by determining the document object type of the XML data to be parsed, according to the corresponding relationship between the document object type and the node configuration information stored in advance, the node configuration information corresponding to the determined document object type is obtained, and then according to the obtained node The node feature data and node data types contained in the configuration information, as well as the way of assigning the business objects of other nodes except the root node to the business objects of its parent nodes, realize the parsing of the XML data to be parsed, which is different from the existing technology. Compared with XML data, it can directly convert XML data into business objects, avoiding the risk of memory overflow caused by the need to build document...

Abstract

The invention discloses an analysis method and an analysis device for XML (extensible markup language) data. By the analysis method and the analysis device, the XML data can be converted into business objects directly, and accordingly, analysis performance is improved obviously. The method includes determining document object type of to-be-analyzed XML data; acquiring node configuration information corresponding to the document object type from pre-stored node configuration information, wherein the node configuration information includes node characteristic data and node data type; performing operation on the data in each line of the XML data sequentially until the XML data are analyzed, wherein the operation refers to determining nodes corresponding to the data in the current line and the data types of the nodes according the node characteristic data and the node data types both included in the node configuration information; analyzing the nodes according to the data types of the nodes to obtain the business objects of the nodes; assigning values of the obtained business objects to business objects of father nodes of the nodes when the nodes are not root nodes in the XML data.

Description

technical field [0001] The present invention relates to the technical field of the Internet, in particular to a method and device for parsing Extensible Markup Language (XML) data. Background technique [0002] Extensible Markup Language (XML), a subset of the standard general markup language, is a markup language used to mark electronic documents to make them structural. It can be used to mark data, define data types, and is a source language that allows users to define their own markup language. It is well-suited for Internet transport, providing a unified method for describing and exchanging structured data independent of applications or vendors. With its own characteristics, XML has become the standard for data information exchange between systems. [0003] Under the Java (computer programming language) language environment, existing XML data parsing technologies mainly include JDOM and DOM4J and so on. [0004] Specifically, when using the JDOM method to parse XML da...
