用java实现对xml的遍历（包括对节点和属性的遍历）

private static void printNode(Node anode) {
	switch (anode.getNodeType()) {
	case Node.ELEMENT_NODE:
		System.out.println(anode.getNodeName() + ", " 
				+ anode.getNodeValue());
if (anode.hasAttributes()) {
	NamedNodeMap attrs = anode.getAttributes();
	for (int i = 0; i < attrs.getLength(); i++) {
		Node node = attrs.item(i);
		System.out.println("\t" + node.getNodeName()
				+ ", " + node.getNodeValue());
	}
}

		break;
	case Node.TEXT_NODE:
		String txtValue = anode.getNodeValue().trim();
if (txtValue.length() > 0)
	System.out.println(anode.getNodeName() 
					+ ", " + txtValue);

		break;
	default:
		System.out.println(
				anode.getNodeName() + ", " 
				+ anode.getNodeValue());
		break;
	}
}
