直接解析xml

1，首先导入相关包
   import org.jdom.Attribute;
   import org.jdom.Document;
   import org.jdom.Element;
   import org.jdom.input.SAXBuilder;
2，根据树状层次结构依次取目录
   SAXBuilder sb = new SAXBuilder();
   Document doc = sb.build(getClass().getResourceAsStream("XXX.xml"));
   Element root = doc.getRootElement(); // 获取根节点
   Element rpts = (Element) root.getChildren("rpts").get(0);
   Element cdma = (Element) rpts.getChildren("cdma").get(0);
   List list = cdma.getChildren();
