这篇文章给大家分享的是有关android使用DOM和SAXParserFactory来解析XML文件的方法的内容。小编觉得挺实用的，因此分享给大家做个参考。一起跟随小编过来看看吧。

对于以下的xml文件:

<?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>

这样来解析:

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) {//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：

@Overrideprotected 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;}@Overridepublic 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;}}@Overridepublic void characters(char[] chars, int start, int length) throws SAXException {super.characters(chars, start, length);getBuffer().append(chars, start, length);}@Overridepublic 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;@Overridepublic String toString() {return "name=" + name + "price=" + price;}}
