XPath is a language used to search for information in XML documents. The following describes how to parse xml using xpath and dom4j in java. for details, refer to the following four methods for parsing XML files.
There are four classic methods to parse
XML files are widely used in lightweight applications developed in PHP, and PHP parses and reads XML files in a variety of ways, such as JS DOM, SIMPLEXML, XPath, and so on, parsing XML files in PHP, and today is about using XPath to parse an instance of
I don't know if you have the same experience as me. Every time you use the XPath algorithm, you have to go through the experiment. Then, you can know the result after the test. I want to say that there is a tool. I should first compile the programming method on the tool, and then I should find this tool in the future,
The following concepts are compiled after reading "no nonsense XML" and "XML manual version 4" in the Super Star PDG format

The core idea of XPath design can be quickly introduced by XPath to the node you want to locate. The main purpose is to describe the position of the node relative to the other nodes, and can get all the nodes that meet the criteria and become the [location path].
