Android's Xmlpull

　　Pull parsing

Pull's XML parsing operations are similar to sax parsing operations and are also event-driven. The corresponding event code is triggered when the XML document starts parsing or encounters a node.

The main concerns are two classes:

Org.xmlpull.v1.XmlPullParserFactory

Org.xmlpull.v1.XmlPullParser

　　

To parse an XML file using Xmlpull:

1. Create a factory class

Xmlpullparserfactory factory = Xmlpullparserfactory.newinstance ();

2. Create Parser

Xmlpullparser xpp = Factory.newpullparser ();

3. Set the input stream, which is what to parse

Xpp.setinput (Input, "GBK"); This is mainly composed of two forms, character stream (e.g. StringReader) or byte stream (e.g. FileInputStream)

4. Through the loop, parse the content

int eventtype = Xpp.geteventtype (); Have to have
while (eventtype! = xmlpullparser.end_document) {

if (EventType = = xmlpullparser.start_document) {

all = new arraylist<linkman> ();
} else if (EventType = = Xmlpullparser.start_tag) {

ElementName = Xpp.getname ();
if ("Linkman". Equals (ElementName)) {

man = new Linkman ();
}
} else if (EventType = = Xmlpullparser.end_tag) {

ElementName = Xpp.getname ();
if ("Linkman". Equals (ElementName)) {

All.add (man);
man = null;
}
} else if (EventType = = Xmlpullparser.text) {

if ("Name". Equals (ElementName)) {

Man.setname (Xpp.gettext ());
} else if ("email". Equals (ElementName)) {

Man.setemail (Xpp.gettext ());
}
}

EventType = Xpp.next (); Be sure to have

}

　　Pull generate XML document

　　Need to take advantage of ORG.XMLPULL.V1. XmlSerializer
