创建XML文档(Create XML Document)

例子 (Demo Example)

Here is the XML we need to create −

<?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>

例子 (Demo Example)

StAXCreateXMLDemo.java

package com.iowiki.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();
      }
   }
}

上述程序将产生以下结果 -

<?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>
