解析XML

[android]代码库

SAX解析：
// 得到工厂类
		SAXParserFactory saxParserFactory = SAXParserFactory.newInstance();
		// 得到解析类
		try {
			SAXParser saxParser = saxParserFactory.newSAXParser();
			// 得到读取类
			XMLReader xmlReader = saxParser.getXMLReader();
			// 设置内容处理者
			xmlReader.setContentHandler(new DefaultHandler() {				
				// 读取文本

				// 读取到结束标签
				@Override
				public void endElement(String uri, String localName,
						String qName) throws SAXException {
					if (localName.equals("student")) {
						list.add(student);						
					}
					tagName = "";
					super.endElement(uri, localName, qName);
				}
				@Override
				public void characters(char[] ch, int start, int length)
						throws SAXException {
					String tag = new String(ch);
					if ("name".equals(tagName)) {
						Log.i("ASD", "开始解析文件"+tag);
						student.setName(tag.trim());
					} else if ("sex".equals(tagName)) {
						student.setSex(tag.trim());
					} else if ("address".equals(tagName)) {
						student.setAddress(tag.trim());
					} else if ("hobby".equals(tagName)) {
						student.setHobby(tag.trim());
					}
					
					super.characters(ch, start, length);
				}

				// 文档读取完毕
				@Override
				public void endDocument() throws SAXException {
					Log.i("ASD", "文件解析完毕");
					super.endDocument();
				}

				// 开始读取文档
				@Override
				public void startDocument() throws SAXException {
					Log.i("ASD", "开始解析文件");
					super.startDocument();
				}

				// 读取到开始标签
				@Override
				public void startElement(String uri, String localName,
						String qName, Attributes attributes)
						throws SAXException {
					tagName = localName;
					if (tagName.equals("student")) {
						Log.i("ASD", "开始解析文件"+tagName);
						student = new Student();
						String id = attributes.getValue("id");
						String age = attributes.getValue("age");
						student.setAge(age.trim());
					}
					super.startElement(uri, localName, qName, attributes);
				}

			});
			xmlReader.parse(new InputSource(getAssets().open("student.xml")));

PULL解析：

// 获取XML文件
			InputStream inputStream = getAssets().open("student.xml");
			pullParser = Xml.newPullParser();
			// 给解析对象设置输入流
			pullParser.setInput(inputStream, "utf_8");
			// 获取xml的标签类型
			int type = pullParser.getEventType();
			// 当没有获取到结束标签时循环执行
			while (type != XmlPullParser.END_DOCUMENT) {
				switch (type) {
				// 开始标签
				case XmlPullParser.START_TAG:
					// 获取开始标签名称
					name = pullParser.getName();
					if (name.equals("student")) {
						student = new Student();
						// 获取开始标签的属性
						//String id = pullParser.getAttributeValue(0);
						String age = pullParser.getAttributeValue(1);
						student.setAge(age);
					} else if (name.equals("name")) {
						String name = pullParser.nextText();
						student.setName(name);
					} else if (name.equals("sex")) {
						String sex = pullParser.nextText();
						student.setSex(sex);
					} else if (name.equals("address")) {
						String address = pullParser.nextText();
						student.setAddress(address);
					} else if (name.equals("hobby")) {
						String hobby = pullParser.nextText();
						student.setHobby(hobby);
					}
					break;
				// 结束标签
				case XmlPullParser.END_TAG:
					name = pullParser.getName();
					if ("student".equals(name)) {
						// 将当前对象添加到集合
						list.add(student);
						student = null;
					}
					break;
				}

				type = pullParser.next();
