Java StAX解析器 创建XML文档

Java StAX解析器 创建XML文档的示例

需要生成的XML文件内容如下

<?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>

编写Java StAX解析器 创建XML文档的程序

package com.yiidian;

import javax.xml.stream.XMLOutputFactory;
import javax.xml.stream.XMLStreamException;
import javax.xml.stream.XMLStreamWriter;
import java.io.IOException;
import java.io.StringWriter;

public class StAXCreateXMLDemo {

   public static void main(String[] args)throws Exception {

      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) {
         e.printStackTrace();
      }
   }
}

输出结果为：
