Answer 1

一条路可走会做手工，通过评估的字符串。 另一种方法是使用所有可用的Java XML库之一... http://en.wikipedia.org/wiki/Java_API_for_XML_Processing

Answer 2

答案是特定于解析器类型的。如果你打算使用DOM解析器，可能this会有所帮助。这些是针对SAX解析器的examples。

public static void main(String[] args) throws MarshalException, 
ValidationException, ParserConfigurationException, SAXException, 
IOException { 

    File fXmlFile = new File(
      "/home/Parsing/src/com/parsing/test.xml"); 
    DocumentBuilderFactory dbFactory = DocumentBuilderFactory.newInstance(); 
    DocumentBuilder dBuilder = dbFactory.newDocumentBuilder(); 
    Document doc = dBuilder.parse(fXmlFile); 

    doc.getDocumentElement().normalize(); 

    Node node = doc.getDocumentElement().getParentNode(); 

    System.out.println(doc.getDocumentElement().getNodeName()); 

    NodeList itemList = node.getChildNodes(); 
    for (int i = 0; i < itemList.getLength(); i++) { 

     Node nNode = itemList.item(i); 

     System.out.println("Current Element : " + nNode.getNodeName()); 

     getChildNode(nNode.getChildNodes()); 

    } 
} 

private static void getChildNode(NodeList childNodes) { // This method is going to retrieve the child nodes 
    // TODO Auto-generated method stub 
    System.out.println(childNodes.getLength()); 

    for (int i = 1; i < childNodes.getLength(); i++) { 
     Node cNode = childNodes.item(i); 

     System.out.println(cNode.getNodeName());

     * This will get the attribute of the node 
     */ 
     if (cNode.hasAttributes()) { 

      NamedNodeMap nodeMap = cNode.getAttributes(); 
      for (int f = 0; f < nodeMap.getLength(); f++) { 
       System.out.println("Att " + nodeMap.item(f).getNodeName() 
         + " " + nodeMap.item(f).getNodeValue()); 
      } 
     } 

     if (cNode.hasChildNodes()) { 

      // For getting the value if node has more than 2 or atleast two childs 

      if (cNode.getChildNodes().getLength() >= 2) { 

       getChildNode(cNode.getChildNodes()); 
      } 

      // For getting the node has no childs and it contains text node value 

      else if (cNode.getNodeType() == cNode.ELEMENT_NODE) { 

       Element ele = (Element) cNode; 
       System.out.println("\t" + ele.getTextContent()); 

      } 
     } 

     i++; 
    }
