演示示例

这是我们需要创建的XML文档：

<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<cars><supercars company="Ferrari">
<carname type="formula one">Ferrari 101</carname>
<carname type="sports">Ferrari 202</carname>
</supercars></cars>

演示示例：

StAXCreateXMLDemo.java

package com.yiibai.xml;

import java.io.IOException;
import java.io.StringWriter;

import javax.xml.stream.XMLOutputFactory;
import javax.xml.stream.XMLStreamException;
import javax.xml.stream.XMLStreamWriter;

public class StAXCreateXMLDemo {
   public static void main(String[] args) {
      try {
         StringWriter stringWriter = new StringWriter();

         XMLOutputFactory xMLOutputFactory = XMLOutputFactory.newInstance();	
         XMLStreamWriter xMLStreamWriter = xMLOutputFactory.createXMLStreamWriter(stringWriter);
   
         xMLStreamWriter.writeStartDocument();
         xMLStreamWriter.writeStartElement("cars");
   
         xMLStreamWriter.writeStartElement("supercars");			
         xMLStreamWriter.writeAttribute("company", "Ferrari");
      
         xMLStreamWriter.writeStartElement("carname");			
         xMLStreamWriter.writeAttribute("type", "formula one");
         xMLStreamWriter.writeCharacters("Ferrari 101");
         xMLStreamWriter.writeEndElement();

         xMLStreamWriter.writeStartElement("carname");			
         xMLStreamWriter.writeAttribute("type", "sports");
         xMLStreamWriter.writeCharacters("Ferrari 202");
         xMLStreamWriter.writeEndElement();

         xMLStreamWriter.writeEndElement();
         xMLStreamWriter.writeEndDocument();

         xMLStreamWriter.flush();
         xMLStreamWriter.close();

         String xmlString = stringWriter.getBuffer().toString();

         stringWriter.close();

         System.out.println(xmlString);

      } catch (XMLStreamException e) {
         e.printStackTrace();
      } catch (IOException e) {
         // TODO Auto-generated catch block
         e.printStackTrace();
      }
   }
}

这将产生以下结果：

<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<cars><supercars company="Ferrari">
<carname type="formula one">Ferrari 101</carname>
<carname type="sports">Ferrari 202</carname>
</supercars></cars>
