Java StAX解析器 - 创建XML文档

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>
