java怎么通过xml节点的属性获取这个节点的值

java怎么通过xml节点的属性获取这个节点的值

创建解析器
SAXReader saxreader = new SAXReader();
读取文档
Document doc = saxreader.read(new File("url"));
获取根
Element root = doc.getRootElement();
获取子节点
List list = root.elements();
System.out.println(e.elementText("name"));
System.out.println(e.element("score").attributeValue("java"));

Reader reader = new InputStreamReader(con
.getInputStream());
SAXReader sax = new SAXReader();
// sax.setEncoding("GBK");
Document document = sax.read(reader);
document.setXMLEncoding("GBK");
Element root = document.getRootElement();
// Document doc = reader.read(read);
// Element root = doc.getRootElement();
readNode(root, "");
public static void readNode(Element root, String prefix) {
if (root == null) return;
// 获取属性
List attrs = root.attributes();
if (attrs != null && attrs.size() > 0) {
System.err.print(prefix);
for (Attribute attr : attrs) {
System.err.print(attr.getValue() + " ");
}
System.err.println();
}
// 获取他的子节点
List childNodes = root.elements();
prefix += " ";
for (Element e : childNodes) {
//输出内容
System.err.println(e.getName()+":"+e.getData());
readNode(e, prefix);
}
}

dom4j架包追问。。。我也知道用这个jar具体方法。。。

//1. 创建解析器
SAXReader saxreader = new SAXReader();

//2. 读取文档
Document doc = saxreader.read(new File("url"));

//3. 获取根
Element root = doc.getRootElement();

//4. 获取子节点
List list = root.elements();

for(Element e : list){

System.out.println(e.elementText("name"));
System.out.println(e.element("score").attributeValue("java"));

}

SAXReader reader = new SAXReader();
            Document document = reader.read(new FileInputStream(f)); //dom4j读取
            String xpath = "/Record/Field[@name='Creator']";//查询属性type='Creator'
            Element element = (Element) document.selectSingleNode(xpath);//得到name=Creator的元素
            System.out.println(element.getText());
