# Java DOM4J解析器 - 创建XML文档 - Java XML教程
## 演示示例
这是我们需要创建的XML文档：
```
Ferrari 101
Ferrari 202
```
**演示示例：**
_CreateXmlFileDemo.java_
```
package com.yiibai.xml;
import java.io.IOException;
import java.io.UnsupportedEncodingException;
import org.dom4j.Document;
import org.dom4j.DocumentHelper;
import org.dom4j.Element;
import org.dom4j.io.OutputFormat;
import org.dom4j.io.XMLWriter;
public class DOM4JCreateXMLDemo {
public static void main(String[] args) {
try {
Document document = DocumentHelper.createDocument();
Element root = document.addElement( "cars" );
Element supercarElement= root.addElement("supercars")
.addAttribute("company", "Ferrai");
supercarElement.addElement("carname")
.addAttribute("type", "Ferrari 101")
.addText("Ferrari 101");
supercarElement.addElement("carname")
.addAttribute("type", "sports")
.addText("Ferrari 202");
// Pretty print the document to System.out
OutputFormat format = OutputFormat.createPrettyPrint();
XMLWriter writer;
writer = new XMLWriter( System.out, format );
writer.write( document );
} catch (UnsupportedEncodingException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
}
}
```
这将产生以下结果:
```
Ferrari 101
Ferrari 202
```
