Android(安卓)读写XML文件(使用pull解析)

pull解析xml文件代码如下：

public void PullParseXML(String filepath) {String res = "本结果是通过XmlPullParse解析:" + "/n";try {XmlPullParserFactory factory = XmlPullParserFactory.newInstance();XmlPullParser xmlPullParser = factory.newPullParser();File file = new File(filepath);if(!file.exists()){CreateXML();file = new File(filepath);}FileInputStream input=null;try {input = new FileInputStream(file);} catch (FileNotFoundException e1) {// TODO Auto-generated catch blocke1.printStackTrace();}if(input == null)return;xmlPullParser.setInput(input,"UTF-8");int eventType = xmlPullParser.getEventType();String str="";try {while (eventType != XmlPullParser.END_DOCUMENT) {String nodeName = xmlPullParser.getName();switch (eventType) {case XmlPullParser.START_TAG:if ("XX1".equals(nodeName)) {str = xmlPullParser.nextText();res += "XX1 = "+str+"--";} else if ("XX2".equals(nodeName)) {str = xmlPullParser.nextText();res += "XX2 = "+str+"--";}else if ("XX3".equals(nodeName)) {str = xmlPullParser.nextText();res += "XX3 = "+str+"--";}else if ("XX4".equals(nodeName)) {str=xmlPullParser.nextText();res += "XX4 = "+str+"--";}else if ("XX5".equals(nodeName)) {str = xmlPullParser.nextText();res += "XX5 = "+str+"--";}break;default:break;}eventType = xmlPullParser.next();}} catch (IOException e) {e.printStackTrace();return;}} catch (XmlPullParserException e) {e.printStackTrace();return;}Log.e("PullParseXML:",res);}

2.写xml文件如下：

public void WriteXml(String filepath) throws IllegalArgumentException, IllegalStateException, IOException {File file = new File(filepath);if(!file.exists()){CreateXML();file = new File(filepath);}FileOutputStream out = null;try {out = new FileOutputStream(file);} catch (FileNotFoundException e) {// TODO Auto-generated catch blocke.printStackTrace();}if(out == null)return;        XmlSerializer serializer = Xml.newSerializer();        serializer.setOutput(out, "UTF-8");        serializer.startDocument("UTF-8", true);                serializer.startTag("", "SettingInfo");        String str = "0";//在此先随便写个数据serializer.startTag("", "XX1");serializer.text(str);serializer.endTag("", "XX1");serializer.startTag("", "XX2");serializer.text(str);serializer.endTag("", "XX2");str = "0";serializer.startTag("", "XX3");serializer.text(str);serializer.endTag("", "XX3");serializer.startTag("", "XX4");serializer.text(str);serializer.endTag("", "XX4");serializer.startTag("", "XX5");serializer.text(str);serializer.endTag("", "XX5");serializer.endTag("", "SettingInfo");        serializer.endDocument();        out.flush();        out.close();    }

---应该有获取xml的tag直接进行数据修改，会的童鞋还请在告知下，谢谢！
