how to get values from same keyname from xml in android -
i have make demo parsing xml response in android,i have tried , goes well,but dont know how values of same argument having same keyname xml response,my sample xml below,
<nightlyratesperroom size="8"> <nightlyrate baserate="315.68" rate="315.68" promo="false"/> <nightlyrate baserate="229.33" rate="229.33" promo="false"/> <nightlyrate baserate="248.52" rate="248.52" promo="false"/> <nightlyrate baserate="267.71" rate="267.71" promo="false"/> <nightlyrate baserate="267.71" rate="267.71" promo="false"/> <nightlyrate baserate="248.52" rate="248.52" promo="false"/> <nightlyrate baserate="286.9" rate="286.9" promo="false"/> <nightlyrate baserate="286.9" rate="286.9" promo="false"/> </nightlyratesperroom> mycode

it's simple. xml parsing, used xmlpullparser. can try code.

to work in android, copy , paste working code try , paste in class. hope helps!
