XPath is a language used to search for information in XML documents. XPath can be used to traverse elements and attributes in XML documents. XPath is the main element of W3C XSLT standards, and XQuery and XPointer are also built on XPath expressions. We recommend a pretty good site: there are good examples in the http:

This article introduces the basic methods for selenium crawling web page data and Automatic Webpage testing. When selenium is used, we often need to find the DOM elements on the page. We must tell selenium how to find the specified element on the page before it can execute events such as clicking and retrieving text. XPath can be used at this time. It is a language used to search for information in XML and HTML documents. Through simple expression, it
