I have been able to get the baclinks for a particular page using the the api.php

http://en.wikipedia.org/w/api.php?action=query&list=backlinks&bltitle=Delhi&bllimit=250&blfilterredir=nonredirects&blnamespace=0&format=php

I have used the php format so that it can be easily parsed.Is there any way to get all the backlinks in one go.Moreover i am only concerned with the number of backlinks. It is possible to get that?
