解析XML文件(二)----使用dom4j方式（二）

<Messages> 
  <Organization>03310100</Organization>  
  <ServiceType>test001</ServiceType>  
  <Extension/>  
  <StartTime>2008-11-10 06:00</StartTime>  
  <Expiry>2015-11-10 23:00</Expiry>  
  <AppId>sx2009bzxcdxt</AppId>  
  <Pad1>10.192.113.11</Pad1>  
  <Message> 
    <Receiver>15601826467</Receiver>  
    <Contents>testContents> 
  </Message> 
</Messages>

创建如上面的xml文件，可以采用另一种方式：

/**
	 * 创建XML报文
	 * 
	 * @param fileName
	 * @param contents
	 * @param phoneNum
	 * @return
	 */
	public String getXML(String filename,String contents,String phoneNum,TUnit unit) {
		SAXReader saxReader = new SAXReader();
		File file;
		XMLWriter writer = null;
		try {
			file = new File(filename);
			Document document = saxReader.read(file);
			Node node = document
					.selectSingleNode("//Messages/Message/Receiver");
			if (phoneNum != null) {
				node.setText(phoneNum);
			}
			node=document.selectSingleNode("//Messages/Organization");
			if(!StringUtil.isNull(unit.getSmsOrgCode())){
				node.setText(unit.getSmsOrgCode());
			}
			node=document.selectSingleNode("//Messages/Extension");
			if(!StringUtil.isNull(unit.getSmsExt())){
				node.setText(unit.getSmsExt());
			}
			node = document.selectSingleNode("//Messages/Message/Contents");
			node.setText(contents);
			OutputFormat format = OutputFormat.createPrettyPrint();
			format.setEncoding("gbk");
			StringWriter out = new StringWriter();
			writer = new XMLWriter(out,format);
			writer.write(document);
			return out.toString();
		} catch (Exception e) {
			log.error("创建XML文件失败",e);
		} finally {
			try {
				writer.close();
			} catch (Exception e) {
				log.error("创建XML文件失败");
			}
		}
	
	}
