This is my xml result return from facebook

<fql_result_set list="true" xmlns="http://api.facebook.com/1.0/"> <comment> <object_id>340982187784

</fql_result_set>

<fql_result_set list="true" xmlns="http://api.facebook.com/1.0/"> <fql_result_set_elt list="true"> <fql_result_set_elt_elt key="object_id">340982187784811202784

The comment tag part is ok. After the comments you see the fql_result_set_elt and fql_result_elt_elt, this is the part goes wrong.

fql_result_set_elt = like tag fql_result_set_elt_elt = object_id tag or user_id

instead of having it on key attribute under fql_result_elt_elt
