android xml解析 XmlPullParser的应用

android xml解析 XmlPullParser的使用

android xml 的解析.

1.普通型

<?xml version=”1.0″ ?><statuses><status><source1>a</source1><source2>a</source2><source2>a</source2></status><statuses></xml>

try{xpp.setInput( new StringReader ( “xml string” ) );XmlPullParser parser = XmlPullParserFactory.newInstance().newPullParser();int eventType = parser.getEventType();while (eventType != XmlPullParser.END_DOCUMENT) {if (eventType == XmlPullParser.START_TAG) {String name = parser.getName();Log.v(“tag”,parser.getName()+”=”+parser.next());}eventType = parser.next();}} catch (XmlPullParserException e) {} catch (Exception e) {}

<?xml version=”1.0″ encoding=”UTF-8″ standalone=”no”?><statuses><status> <source1>a</source1> <source2>a</source2> <source2>a</source2> <user>   <source1>a</source1>   <source2>a</source2>   <source2>a</source2> </user></status><status> <source1>a</source1> <source2>a</source2> <source2>a</source2> <user>   <source1>a</source1>   <source2>a</source2>   <source2>a</source2> </user></status><statuses></xml>

try{XmlPullParser parser = XmlPullParserFactory.newInstance().newPullParser(); xpp.setInput( new StringReader ( xml string ) );parser.next();parser.require(XmlPullParser.START_TAG, null, “statuses”);while (parser.nextTag() != XmlPullParser.END_TAG) {parser.require(XmlPullParser.START_TAG, null, “status”);for (int i=0;i<3;i++){parser.nextTag();Log.v(“tag”,parser.getName()+”=”+ parser.nextText());}while (parser.nextTag() != XmlPullParser.END_TAG) {parser.require(XmlPullParser.START_TAG, null, “user”);while (parser.nextTag() != XmlPullParser.END_TAG) {String name = parser.getName();String text2 = parser.nextText();Log.v(“tag”,”text2″+text2);parser.require(XmlPullParser.END_TAG, null, name);}parser.require(XmlPullParser.END_TAG, null, “user”);}parser.require(XmlPullParser.END_TAG, null, “status”);}parser.require(XmlPullParser.END_TAG, null, “statuses”);parser.next();parser.require(XmlPullParser.END_DOCUMENT, null, null);// global.userinfo.dump();} catch (XmlPullParserException e) {} catch (Exception e) {}

for (int i=0;i<3;i++){parser.nextTag();Log.v(“tag”,parser.getName()+”=”+ parser.nextText());}
