How can I read it and fill ListView in Android, and what should I do : DOM , XML Parser or SAX ??

Answer 1

I prefer DOM for small little snippets like this.

String xml;
Document doc;
Element root = null;
try {
    DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
    DocumentBuilder builder = factory.newDocumentBuilder();
    doc = builder.parse( new InputSource( new StringReader( xml ) ) );
    root = doc.getDocumentElement();
} catch ( Exception e ) {
    // do something
}

if( root != null ) {
    NodeList cats = root.getElementsByTagName( "category" );
    for( int i=0; i < cats.getLength(); i++ ) {
    Element category = (Element)cats.item( i );
        ....
    }
}
