java读取xml(二)

关于xml和上一篇文章一样
public void printNodeInfo(Node node) {
System.out.println(node.getNodeName() + ":" + node.getNodeValue());
}
public void printNode(Node node) {
switch (node.getNodeType()) {
case Node.PROCESSING_INSTRUCTION_NODE:
System.out.println("--------------PI start---------------------");
printNodeInfo(node);
System.out.println("--------------PI end---------------------");
break;
case Node.ELEMENT_NODE:
System.out
.println("--------------element start---------------------");
printNodeInfo(node);
NamedNodeMap attrs = node.getAttributes();
for (int i = 0; i < attrs.getLength(); i++) {
System.out
.println("-------------------attr start--------------------");
System.out.println(attrs.item(i));
System.out
.println("-------------------attr end--------------------");
}
System.out
.println("--------------element end---------------------");
break;
case Node.TEXT_NODE:
printNodeInfo(node);
break;
default:
break;
}
/*
* 递归调用
*/
Node child = node.getFirstChild();
while (child != null) {
printNode(child);
child = child.getNextSibling();
}
}
public static void main(String[] args) {

domPri.printNode(doc);
} catch (ParserConfigurationException e) {
e.printStackTrace();
} catch (SAXException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
