please have a look at the site oddsportal.com which have more than 60 bookmarkers from which they get the XML feeds for their site.
1. I want to know how they handle them using php?
2. And in some bookmarkers sites (see the list at http://www.oddsportal.com/bookmakers/) many of them dont have link to their XML feeds in the site then how this oddsportal alone get XML feeds from them?
