                                  .

the first attributes have a mp3 file in same file name . the file name denoted in ** ** and next two also have a mp3 file in same file name.so i want to show a listview according to file names.first i want show a listview like this

 Terry_Waychuk

 The_Grimey_Tech

after click on anyone of these then show a listview as mp3 file titles(that first two in Terry_Waychuk and next two in The_Grimey_Tech). so please tell me how to get the particular name in attribute value and also how to add that particular mp3 files to that folder(Terry_Waychuk or The_Grimey_Tech).

One way using the android XmlPullParser (you didn't specify which one you were using) is to pull the attributes into a Map<String, String> when you receive a XmlPullParser.START_TAG, so, assuming a main parse::

private void parseContent(XmlPullParser parser) 
    throws XmlPullParserException,IOException,Exception {
    int eventType;
    while((eventType=parser.next()) != XmlPullParser.END_TAG) {
        if (eventType == XmlPullParser.START_TAG) {
            Log.d(MY_DEBUG_TAG,"Parsing Attributes for ["+parser.getName()+"]");
            Map<String,String> attributes = getAttributes(parser);
        }
        else if(eventType==...);
        else {
            throw new Exception("Invalid tag at content parse");
        }
    }
}

private Map<String,String>  getAttributes(XmlPullParser parser) throws Exception {
    Map<String,String> attrs=null;
    int acount=parser.getAttributeCount();
    if(acount != -1) {
        Log.d(MY_DEBUG_TAG,"Attributes for ["+parser.getName()+"]");
        attrs = new HashMap<String,String>(acount);
        for(int x=0;x<acount;x++) {
            Log.d(MY_DEBUG_TAG,"\t["+parser.getAttributeName(x)+"]=" +
                    "["+parser.getAttributeValue(x)+"]");
            attrs.put(parser.getAttributeName(x), parser.getAttributeValue(x));
        }
    }
    else {
        throw new Exception("Required entity attributes missing");
    }
    return attrs;
}

The parser.getName() returns the name of the entity associated to the XmlPullParser.START_TAG.

Hope this helps
