解析的程序

package sunline.subsystem.expr.common.logic;

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

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

public class ReadXmlTest {
public static void main(String[] args) {
File xmlFile = new File("D:/test.xml");//指定路径、
FileInputStream fis = null;
try{
fis = new FileInputStream(xmlFile);
}catch (FileNotFoundException e) {
e.printStackTrace();
System.out.println("file not exsit !");
}

SAXReader saxReader = new SAXReader();
saxReader.setEncoding("gbk");
Element rootElement = null;
List<Element> elements = null;
try{
//生成文档实体
Document doc = saxReader.read(fis);
rootElement = doc.getRootElement();
}catch (DocumentException e) {
e.printStackTrace();
}
printValue(rootElement);

}

*使用递归对整个节点进行解析

*/
private static void printValue(Element e){
if (e.elements().size() == 0) {//当节点没有子节点的时候
System.out.println("Name:"+e.getName()+",Value:"+e.getText());
return;
}
for ( Iterator iterInner = e.elementIterator(); iterInner.hasNext(); ) {//如果该节点存在子节点
Element elementInner = (Element) iterInner.next();
printValue(elementInner);
}
}
}
