Java dom4j Parsing XML file code instance sharing _java

There are two ways to parse XML files, one is to use DOM to parse, this way to write code more trouble, for the first programmers are more prone to problems; the second is to use the DOM4J package to parse
When you want to use the DOM4J package, you must first introduce the package

Copy Code code as follows:

Import Java.io.File;
Import Java.io.FileWriter;
Import java.io.IOException;
Import Java.io.Writer;
Import Java.util.Iterator;

Import org.dom4j.Document;
Import org.dom4j.DocumentException;
Import Org.dom4j.DocumentHelper;
Import org.dom4j.Element;
Import Org.dom4j.io.OutputFormat;
Import Org.dom4j.io.SAXReader;
Import Org.dom4j.io.XMLWriter;
