This method is a very powerful way to find elements, which can be used to locate almost any element on the page. Before we can formally start using XPath for positioning, let's take a look at what XPath is. XPath is the abbreviation for XML path, because the HTML document itself is a standa
1 Analysis of XML files in 4 ways
There are usually four classical methods for parsing XML files. There are two basic parsing methods, one called Sax and the other called Dom. Sax is based on parsing of event streams, and Dom is based on XML document tree structure parsing. On this basis, in order to reduce the number of DOM, Sax coding, there are jdom, the advantage is that the 20-80 principle (Pareto Law), greatly reducing the amount of code. In general, Jdom is used to meet the requirements

The XPath that was misused in the seleniumIn the process of automating testing with selenium, it is a common task to select the elements on the page and perform various operations on them. Selenium offers a variety of positioning methods:
ID: The most effective and convenient method
Name: Similar to ID class
Class name: A good way to clean sweep some elements with the same class
Link text and Partial link text: Used to locate hype
In selenium automation, if the ID, class, name, etc General Locator cannot find the element, the XPath is used to find the element on the Web page.This time I will explain from the following three aspects:1. What is XPath2. Use of XPath syntax3. Use XPath to handle complex and dynamic elements in selenium1. XPath is an
