dom4j解析XML文档

在下载并配置了jar包之后

首先要获取xml文档的路径，使用SAXReader的read方法来读取XML

之后就可以获取他的全部节点

package dom4j;

import java.io.File;
import java.util.Iterator;
import java.util.List;

import org.dom4j.Document;
import org.dom4j.DocumentException;
import org.dom4j.Element;
import org.dom4j.io.OutputFormat;
import org.dom4j.io.SAXReader;
import org.dom4j.io.XMLWriter;

public class test2 {

public static void main(String[] args) {
// TODO Auto-generated method stub
try {
//构建XML文档对象
SAXReader reader = new SAXReader();
Document document = reader.read(new File("E:/work_javase/dom4j/src/dom4j/user.hbm.xml"));
//获取根节点
Element root = document.getRootElement();
OutputFormat format = OutputFormat.createPrettyPrint();
//System.out.print(root);
XMLWriter writer2 = new XMLWriter(System.out,format);
//writer2.write(format);
//获取指定子节点
Element element1 = root.element("class");
System.out.println(element1);
//获取多个节点存放在List集合中
List<Element> itemElements = root.elements("property");
Iterator<Element> iterator = itemElements.iterator();
while (iterator.hasNext()) {
Element element = (Element) iterator.next();
System.out.println(element);
}
} catch (Exception e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}

}
