心情: 一般
String xml = "
SAXReader sax = new SAXReader();
Document doc = sax.read(new StringReader(xml));
Node name = doc.selectSingleNode("//song/name");
System.out.println(name.getStringValue());
Node singer = doc.selectSingleNode("//song/singer");
System.out.println(singer.getStringValue());
这其中需要用到dom4j以及jaxen这两个包，其中jaxen是XPath的实现。
