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 {    	@Override  	protected 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) {  						//这里才表示这个是<book>节点  						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;  	}

采用SAXParserFactory：

@Override  	protected void onCreate(Bundle savedInstanceState) {  		super.onCreate(savedInstanceState);  		SAXParserFactory factory = SAXParserFactory.newInstance();    		try {  			SAXParser saxParser = factory.newSAXParser();  			InputStream is = this.getAssets().open("test1.xml", Context.MODE_PRIVATE);  			saxParser.parse(is, new MyDefaultHandler());  		} catch (Exception ex) {    		}  		System.out.println("===size=" + list.size());  		for (int i = 0; i < list.size(); i++) {  			Book book = list.get(i);  			Log.d("TAG", "name=" + book.name + "email=" + book.email);  		}  	}    	protected String getElementName(String name, String qName) {  		if ("".equals(name)) {  			return qName;  		} else {  			return name;  		}  	}    	class MyDefaultHandler extends DefaultHandler {    		private StringBuffer buf;  		private Book mBook;    		public MyDefaultHandler() {  			super();  			mBook = new Book();  		}    		protected StringBuffer getBuffer() {  			return this.buf;  		}    		@Override  		public void startElement(String uri, String localName, String qName, Attributes attributes) throws SAXException {  			super.startElement(uri, localName, qName, attributes);  			buf = new StringBuffer();  			for (int i = 0; i < attributes.getLength(); i++) {  				String value = attributes.getValue(i);  				mBook.email = value;  			}    		}    		@Override  		public void characters(char[] chars, int start, int length) throws SAXException {  			super.characters(chars, start, length);  			getBuffer().append(chars, start, length);  		}    		@Override  		public void endElement(String uri, String localName, String qName) throws SAXException {  			super.endElement(uri, localName, qName);  			String elementName = getElementName(localName, qName);  			if (elementName.equals("book")) {  				list.add(mBook);  				mBook = new Book();  			} else if (elementName.equals("name")) {  				mBook.name = getBuffer().toString();  			} else if (elementName.equals("price")) {  				mBook.price = getBuffer().toString();  			}    		}    	}    	private ArrayList<Book> list = new ArrayList<Book>();    	private class Book {  		String email;  		String name;  		String price;    		@Override  		public String toString() {  			return "name=" + name + "price=" + price;  		}    	}
