Dom4j generates and parses XML documents

Dom4j is a very good Java xml api with excellent performance, powerful functionality and extreme ease of use. It is also an open source software. Now you can see that more and more Java software are using dom4j to read and write XML. It is particularly worth mentioning that Sun's jaxm is also using dom4j.

XML file

<?xml version="1.0" encoding="UTF-8"?> <employees> <employee> <name>ddviplinux</name> <sex>m</sex> <age>30</age> </employee> </employees>
