XMLStringToDocument

今天做的项目需要解析XML字符串,看过 http://www.blogjava.net/JAVA-HE/archive/2007/02/07/98527.html这位仁兄写的解析,觉得漏洞挺多的:1.因为是用Properties存值的,所以子节点不能重复;2.当将XML改成有几层关系之后,父节点取值就会出错.所以用Document来做了,代码:

public static void main(String[] args) throws SAXException, IOException, ParserConfigurationException {
		InputStream inputStream=new  ByteArrayInputStream(XML().getBytes());
		Document document=DocumentBuilderFactory.newInstance().newDocumentBuilder().parse(inputStream);
		NodeList nodeList=document.getElementsByTagName("value");
		System.out.println(nodeList.item(1).getTextContent());
	}
	private static String XML(){
		String xmlStr="<?xml version='1.0' encoding='UTF-8'?>"+
						"<xml-body>"+
						"<value> "+
                                                "<test>1</test>"+
                                                "<test>2</test></value>"+
						"<value>2</value>"+
						"<value>3</value>"+
						"</xml-body>";
		return xmlStr;
	}

缺点:Domcument通常需要加载成整个文档,大一点的数据就不行了.
