time to study the code. First, you need to add an entry point to package the Java objects into an XML document. As with the Unmarshaller class, it is easiest for other programs to use packaged code from a static method. If there is no option to pass in the Java object, as discussed here, this approach works.

To analyze this structure, you usually need to load the entire document and construct a hierarchy before you can perform anyWork. Because it is based on information layers, Dom is considered to be tree-based or object-based. DomTree-based processing in the broad sense has several advantages. First, because the tree is persistent in the

Xml dom parser
We already know the concept of xml dom. parser is used for XML and Dom conversion.
As we all know, there are more and more ways to parse XML, but there are four main approaches: DOM, SAX, Jdom, and dom4j
The following first gives the jar package download addresses for these four methods

1. XML Syntax Parsing Method
XML parsing is a theoretical knowledge, not only in Java, but also in other languages. There are currently three types:
A. Dom (Document Object Model): the DOM method reads all XML content into the memory at a time and generates a tree structure
