android如何使用DOM來解析XML檔案

標籤：dom

對於以下的xml檔案:

<?xml version="1.0" encoding="UTF-8"?><!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd"><books>      <book email="zhoujunhui">          <name>rjzjh</name>          <price>jjjjjj</price>      </book>       <book email="aaaaaaaaa">          <name>bbbb</name>          <price>ccc</price>      </book>  </books>  

這樣來解析:

import java.util.ArrayList;import javax.xml.parsers.DocumentBuilder;import javax.xml.parsers.DocumentBuilderFactory;import org.w3c.dom.Document;import org.w3c.dom.Element;import org.w3c.dom.Node;import org.w3c.dom.NodeList;import android.app.Activity;import android.content.Context;import android.content.Intent;import android.content.res.AssetManager;import android.os.Bundle;import android.util.Log;public class TestActivity extends Activity {@Overrideprotected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);XmlReader();for(int i=0;i<list.size();i++) {Book book = list.get(i);Log.d("TAG", "name="+book.name+"email="+book.email);}}public void XmlReader() {Document doc = null;AssetManager assetManager = this.getAssets();DocumentBuilder docBuilder = null;DocumentBuilderFactory docBuilderFactory = null;try {docBuilderFactory = DocumentBuilderFactory.newInstance();docBuilder = docBuilderFactory.newDocumentBuilder();doc = docBuilder.parse(assetManager.open("test1.xml"));Element root = doc.getDocumentElement();NodeList books = root.getChildNodes();if (books != null) {for (int i = 0; i < books.getLength(); i++) {Node book = books.item(i);Book mybook = null;if (book.getNodeType() == Node.ELEMENT_NODE) {//這裡才表示這個是<book>節點mybook = new Book();String email = book.getAttributes().getNamedItem("email").getNodeValue();mybook.email = email;for (Node node = book.getFirstChild(); node != null; node = node.getNextSibling()) {if (node.getNodeType() == Node.ELEMENT_NODE) {if (node.getNodeName().equals("name")) {String name1 = node.getFirstChild().getNodeValue();mybook.name = name1;}if (node.getNodeName().equals("price")) {String price = node.getFirstChild().getNodeValue();mybook.price = price;}}}list.add(mybook);}}}} catch (Exception e) {e.printStackTrace();}}private ArrayList<Book> list = new ArrayList<Book>();private class Book{String email;String name;String price;}
