用dom解析xml

解析用到这个就够了

text = "<root><persion age=\"18\"><name>xiao</name><sex>m</sex></persion></root>";
		System.out.println("wodelakdjkfajsdf");
		
		DocumentBuilderFactory domfac = DocumentBuilderFactory.newInstance();
		try{
			DocumentBuilder domBuilder = domfac.newDocumentBuilder();
			Document doc = domBuilder.parse(new InputSource(new StringReader(text)));
			
			Node root = doc.getDocumentElement();
			if(root.hasChildNodes()){
				NodeList nodes = root.getChildNodes();
				for(int i = 0; i< nodes.getLength(); i++){
					Node node = nodes.item(i);
					System.out.println(node.getAttributes().getNamedItem("age").getNodeValue());
					NodeList cnodes = node.getChildNodes();
					for(int j = 0; j< cnodes.getLength(); j++){
						Node cnode = cnodes.item(j);
						System.out.println(cnode.getNodeName());
						System.out.println(cnode.getTextContent());
					}
				}
			}
