This article mainly introduces the use of namespace in XML parsing, has a certain reference value, interested friends can refer to, I hope you can learn a lot after reading this article, the following let the editor take you to understand it.

There is no need to say much about the meaning of namespace. Like high-level languages such as Category, XML also faces the problem of variable renaming when a large number of files are put together, so namespace is used to separate variables with the same name and different meanings. This paper focuses on the parsing method of namespace.

Here is a simple XML file:

Hello world one

There is no namespace in this example. I'm afraid the examples we came into contact with when we first learned XML are all like this. This kind of example is misleading. After parsing hello world, beginners happily use the same program to parse the actual XML file, and often fail. The following is a XML file returned by Douban API

See so many www do not want to see directly skip, and then see the familiar, decisively apply the above example of the program, a run but get nothing, what is the problem? C # provides a lot of XML classes, XDocument, XReader, XPath, XmlDocument. I'm not sure if the kind I use now is not good enough. I'm not sure I have to try it at random. I just try it all night. Children's shoes, let's calm down and take a look at them line by line.

This line doesn't look good. Look down here.
