dom4j创建、解析XML jar包提供下载

dom4j创建XML：

//用dom4j生成xml文件
		Document document = DocumentHelper.createDocument();
		Element newspaperElement = document.addElement("NewspaperSync.REQ");
		newspaperElement.addComment("this is a newspaper xml");
	    newspaperElement.addProcessingInstruction("MsgHeader", "text");
		Element msgHeaderElement = newspaperElement.addElement("MsgHeader");
		Element transactionIDElement = msgHeaderElement.addElement("TransactionID");
		for(int i=1;i<5;i++){
			Element id = transactionIDElement.addElement("ID");
			id.setText("i"+i);
		}
		Element timestampElement = msgHeaderElement.addElement("Timestamp");
		Element viasElement = msgHeaderElement.addElement("Vias");
		Element viaElement = viasElement.addElement("Via");
		viaElement.setText("100.2000.12345");
		Element viabakElement = viasElement.addElement("Via");
		viabakElement.setText("200.3000.56789");
		try{
			OutputFormat format = OutputFormat.createPrettyPrint();
			XMLWriter output = new XMLWriter(new FileWriter(new File(sendESGxml+"1111.xml")), format);  //sendESGxml是路径
			output.write(document);
			output.close();
		}catch(IOException e){
			System.out.println(e.getMessage());
		}

dom4j解析XML，并修改其中内容：
SAXReader saxReader = new SAXReader();
		Document document = saxReader.read(new File("f:/xml/1111.xml"));
		List list = document.selectNodes("//MsgHeader/TransactionID");
		Iterator iterator = list.iterator();
		while(iterator.hasNext()){
			Element element = (Element) iterator.next();
			Iterator iter = element.elementIterator("ID");
			while(iter.hasNext()){
				Element idElement = (Element)iter.next();
				if(idElement.getText().equals("i2")){
					idElement.setText("island");
				}
			}
		}
		XMLWriter output = new XMLWriter(new FileWriter(new File("c:/22.xml")));
		output.write(document);
		output.close();
	}

其中用到了2个包：分别是dom4j-1.6.1.jar和jaxen.jar

注：在创建xml时只需要dom4j包就可以了，而在解析修改xml的时候必须有jaxen包才行，否则会报错。

下载jar包的资源很好
