The XML namespace provides a way to avoid element naming conflicts.Name Conflict
Because the elements used in the XML document are not fixed, two different XML documents may use the same name to describe different types of elements. In this case, naming conflicts often occur. See the following two examples.

. NET provides excellent support for XML reading and writing, and provides many classes in the. NET Framework XML namespace to read and write XML files. When you need to read and write XML files, you can enter using system. xml at
This is a bit abstract, not easy to understand, and I have learned a little bit, but it is very remarkable. It brings us a lot of convenience in XML applications, the XML function has also been greatly improved, and I feel like it. Oh, there is something wrong with it. Don't laugh!Before entering the subject, we will reference an example:In the above XML, it is a
Removing XML namespaces and declaring headers does not affect deserialization.Directly on the code:Serialize this object int obj = 1; XmlSerializer serializer = new XmlSerializer (obj. GetType ());//Serialize the object output to a file FileStream stream = new FileStream ("Hh.xml", FileMode.Create); XmlWriterSettings settings = new XmlWriterSettings (); settings. Indent = true;settings. IndentChars = " "; settings. Newlinechars = "\ r \ n"; setting

Before introducing the XML namespace, let's take a look at the XML Code Section:
This code is taken from a configuration code section of the Spring framework.
A Brief Analysis: many elements in this section of XML Code do not use any prefix, because their defau

After the XML parser parses the XML document and passes the data to the application, the application needs to combine elements from different documents into the same XML document. Whether you are in the same document or in a different document, you can add a prefix to each element in order to resolve the problem of naming conflicts. However, this approach also ha
