java中使用dom4j写xml文件和简单教程

 
下载 dom4j-1.6.1.jar。
1: package org.zzp.common.xml.dom4j;
2:
3: import java.io.FileWriter;
4: import java.io.IOException;
5: import org.dom4j.Document;
6: import org.dom4j.DocumentHelper;
7: import org.dom4j.Element;
8: import org.dom4j.io.OutputFormat;
9: import org.dom4j.io.XMLWriter;
10:
11: public class Dom4jDemo {
12: public static void main(String[] args) {
13: Document doc=DocumentHelper.createDocument();
14: Element root=doc.addElement("students");
15: Element s1=root.addElement("student");
16: s1.addElement("id","1");
17: Element name=s1.addElement("name","王建宙");
18: name.addAttribute("sex", "非");
19: OutputFormat format=OutputFormat.createPrettyPrint();
20: format.setEncoding("gbk");
21: try {
22: XMLWriter out=new XMLWriter(new FileWriter("test.xml"),format);
23: out.write(doc);
24: out.close();
25: } catch (IOException e) {
26: // TODO Auto-generated catch block
27: e.printStackTrace();
28: }
29: }
30: }
ok.我们来看看test.xml的内容
1: <?xml version="1.0" encoding="gbk"?>
2:
3: <students>
4: <student>
5: <id xmlns="1"/>
6: <name xmlns="王建宙" sex="非"/>
7: </student>
8: </students>
。。。怎么会这样。。<id xmlns=”1” />怎么变这样的
我要的是“<id>1</id>”啊。。
那么正确的应该怎么写呢。。我们来看看
1: package org.zzp.common.xml.dom4j;
2:
3: import java.io.FileWriter;
4: import java.io.IOException;
5: import org.dom4j.Document;
6: import org.dom4j.DocumentHelper;
7: import org.dom4j.Element;
8: import org.dom4j.io.OutputFormat;
9: import org.dom4j.io.XMLWriter;
10:
11: public class Dom4jDemo {
12: public static void main(String[] args) {
13: Document
