android中常见的二种数据解析方法----XML和Json

<span style="font-size:18px;">String xmlStr = "<apps><app><id>1</id><name>google</name></app><app><id>2</id><name>ie</name></app><app><id>3</id><name>chrome</name></app></apps>";

public void parseXMLWrithPull(String xmlStr) {
try {
XmlPullParserFactory factory = XmlPullParserFactory.newInstance();
XmlPullParser xmlPullParser = factory.newPullParser();
xmlPullParser.setInput(new StringReader(xmlStr));
int eventType = xmlPullParser.getEventType();
String id = "";
String name = "";
while(eventType != XmlPullParser.END_DOCUMENT) {
String nodeName = xmlPullParser.getName();
switch (eventType) {
case XmlPullParser.START_TAG:
if("id".equals(nodeName)) {
id = xmlPullParser.nextText();
} else if("name".equals(nodeName)) {
name = xmlPullParser.nextText();
}
break;

case XmlPullParser.END_TAG:
if("app".equals(nodeName)) {
Log.i("id=", id);
Log.i("name=", name);
}
break;

default:
break;
}
}

} catch (Exception e) {
e.printStackTrace();
