java怎么通过xml节点的属性获取这个节点的值

如题我给个xml示例吧
<Record>
<Field name="Title" WordPos="0,4">java</Field>
<Field name="AlternativeTitle" WordPos="">21</Field>
<Field name="Creator" WordPos="">肖磊</Field>
</Record>
就是怎么通过Field 的 name属性值获取相应Field 节点的值，就是获取 java 、21、肖磊
求大哥大姐明示，写上具体的获取方法。感激不尽！

Answer 1

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<Element> list = root.elements();

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

1. Reader reader = new InputStreamReader(con
   .getInputStream());
   SAXReader sax = new SAXReader();
   // sax.setEncoding("GBK");

2. Document document = sax.read(reader);
   document.setXMLEncoding("GBK");
   Element root = document.getRootElement();
   // Document doc = reader.read(read);
   // Element root = doc.getRootElement();
   readNode(root, "");

3. public static void readNode(Element root, String prefix) {
   if (root == null) return;
   // 获取属性
   List<Attribute> 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();
   }

4. // 获取他的子节点
   List<Element> childNodes = root.elements();
   prefix += "\t";
   for (Element e : childNodes) {
   //输出内容
   System.err.println(e.getName()+":"+e.getData());
   readNode(e, prefix);
   }
   }

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());

//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<Element> list = root.elements();

for(Element e : list){

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

}

dom4j架包

追问

。。。我也知道用这个jar具体方法。。。
