I have made a parser,in that i am getting all the values of that xml tag,But i want to get some values which are inside tag as an argument,I dont know how to get it from tags,The sample xml is as below: sample.xml

<ChargeableRateInfo averageBaseRate="226.7" averageRate="192.69" commissionableUsdTotal="192.69" currencyCode="USD" maxNightlyRate="192.69" nightlyRateTotal="192.69" surchargeTotal="46.8" total="239.49"><NightlyRatesPerRoom size="1"><NightlyRate baseRate="226.7" rate="192.69" promo="true"/></NightlyRatesPerRoom>

,I want to get value of "averageRate","nightlyRateTotal","total",But I have no idea how to get that data?My parser is as below:

while (eventType != XmlPullParser.END_DOCUMENT && !done) {
                tagName = parser.getName();

                switch (eventType) {

                    break;
                case XmlPullParser.START_TAG:
                    if (tagName.equals(ITEM)) {
                        rssFeed = new RSSFeed_SelectedHotelResult();

                    }

                    if (tagName.equals(DESCRIPTION)) {
