Method and system for recovering xml configuration files based on xpath

Abstract

The invention provides an XPATH (XML Path Language)-based XML (Extensible Markup Language) configuration file recovery method and a system thereof. The method comprises the steps of: traversing all leaf nodes in a first configuration file released with a version and acquiring absolute paths of all leaf nodes; inquiring whether corresponding leaf nodes exist in a second configuration file by use of an XPATH according to the absolute paths, wherein the second configuration file is a configuration file stored on a storage medium; and if so, writing values of the leaf nodes in the second configuration file into the corresponding leaf nodes in the first configuration file. According to the XPATH-based XML configuration file recovery method and the system thereof, when the system restarts configurations, user configuration files stored on the storage medium can be exactly and rapidly recovered to a running configuration file released with the version, and an XML configuration file-based application program can be guaranteed to run normally.

Description

technical field [0001] The invention relates to the application field of XML language, in particular to an XPATH-based XML configuration file recovery method and system thereof. Background technique [0002] XML language, as an extensible markup language, is a source language that allows users to define their own markup language. As long as certain rules are followed, the scalability of XML is almost unlimited, and this extension does not require structural confusion or Affect the basic configuration at the cost. Management information in XML document format can be easily transmitted through HTTP protocol. Since HTTP is built on TCP, management data can be transmitted reliably. XML also supports standard APIs for accessing XML documents, such as DOM, etc. The XML format is a W3C standard, common to various platforms, and has good portability. [0003] XPATH is the XML path language, which is a language used to determine the location of a certain part in an XML document. B...

Problems solved by technology

In this way, there is a problem: when the system is restarted, the content of the XML configuration file saved on the storage medium needs to be restored to the running configuration file released with the version

[0005] For the above-mentioned problem of restoring the content of the XML configuration file saved on the storable medium to the running configuration file released with the version when the system is restarted, there is currently no complete solution, and, after restoring the XML After configuration, the XML configuration run by the system is the XML configuration saved on the storable medium, so that the application program cannot support modifying the original default value when the version is released, and the modification includes the user's modification of the XML configuration file on the storable medium modification, as well as the modification of the XML configuration file released by the software developer, but there is often a need for this in actual use

[0006] Based on the above problems, the Chinese patent application No. 201310100931.4 discloses a data recovery method based on the structure summary, mentions the use of XPATH to recover the node information of interest in XML, specifically discloses how to parse the XPATH query statement and how to restore the sense XML node data of interest, does not provide a way to restore content from one XML configuration file to another XML configuration file

Another Chinese patent application with patent application number 201110200086.9 discloses an XML fragmentation method based on query workload estimation, specifically discloses a method for traversing XML nodes to realize XML fragmentation, but also does not provide a good solution to the above problem approach

[0007] Therefore, it is necessary to provide an XPATH-based XML configuration file recovery method and its system, which can solve the problem that the prior art does not provide a feasible solution for the recovery of XML configuration files for applications that use XML files to save configurations
