Embodiment Construction

[0022]The present invention is mainly applied to XML compressed data that separates and compresses XML structure and data. When extracting XML compressed data, decompress it first and then parse the computer resource consumption caused by string operations in the process of parsing, and improve the efficiency of program operation. The method and device for processing XML compressed data according to the present invention will be described in detail below with reference to the drawings and embodiments.

[0023] In the present invention, a mixed data type is defined, and the XML structure information and XML data in the XML compressed data are represented by means of "data type mark + data", and multiple types of data are directly transmitted between program interfaces, reducing characters String type usage. Specifically, in the mixed data type, the data type mark represents various data types, and the data storage part stores data, specifically, for digital data, its original ...

Abstract

The invention provides a method and connector for rapidly reading XML (Extensible Markup Language) compressed data. XML compressed data are converted into hybrid data type objects to generate a message sequence including the hybrid data type objects, wherein the hybrid data type adopts a mode of data type marks and data storage part. Correspondingly, the invention provides a method and device forrapidly processing the XML compressed data. The method comprises the steps of: generating a message sequence comprising the hybrid data type objects through converting the XML compressed data into the hybrid data type objects; searching corresponding data processing logic according to the read hybrid data type objects in the message sequence and converting hybrid data, and transmitting the converted data to the searched data processing logic. Through the hybrid data types and the flow read interface, for the XML structure information and some types of data, the read original compressed data are directly transmitted, thus the operation consumption and the storage consumption caused by character string operation are saved.

Description

technical field [0001] The invention relates to the field of XML data processing, in particular to a method and device for rapidly processing XML compressed data. Background technique [0002] Among the existing XML data compression methods, there are many compression methods based on XML structure and data characteristics processing methods, such as XGRIND, XPRESS and so on. In these methods, on the one hand, avoid using the original XML container to represent the structure, and directly save the XML structure information in the compressed data, so as to realize the direct query of the compressed data; Types or data with similar characteristics are compressed together to achieve a higher data compression ratio. When reading information from this kind of compressed data that separates the structure and data, the usual practice is to decompress the original XML data first, and then use the known XML parsing method to parse. For related content, please refer to the patent No....
