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, currently, sketchpath is bate, but it is easy to use.

XPath is now rarely used by us because JSON is now prevalent. But in the age of XML as a data Interchange format, XPath plays a very important role when we randomly access large XML document structures. Perhaps many of you are now not aware that the DOM level 3 XPath-specified interface has been implemented by Firefox,safari, Chrome, and opera. The core interface

XPath can be compared to a file management path: Through the file management path, you can find the required files according to certain rules, and also, depending on the rules set by XPath, you can easily find any node in the XML Struc

Every person who writes a crawler, or does a Web page analysis, believes that it will take a lot of time to locate, get the XPath path, and even sometimes when the crawler framework matures, basically the main time is spent on page parsing. In the absence of these aids, we can only search the HTML source code, locate some ID to find the corresponding location, very troublesome, and often error. Here is an XPath
