SAXReader解析XML

阅读更多

总结：

Document document=new SAXReader.reader(“xml文路径/文件名xxx.xml”);//得到Document对象

Element root = document.getRootElement()//获得根节点

Iterator iterator=root.elementIterator(); //从根节点遍历子节点

Iterator iterator=Element.elementIterator(); //再从子节点在遍历其子节点

对节点访问其属性用：Attribute leaderAttr =Element. attribute(“xxx”);

对节点访问其某个属性leaderAttr的名称：leaderAttr.getName()；
对节点访问其某个属性leaderAttr的值：leaderAttr.getValue()

对节点访问其名称：Element.getName();

对节点访问其文本：Element. getText();
