thanks Michael...
just to make sure i understand before i proceed...
so I generate a unique id for the current context of <<b>>...
(which defines a local variable named $id) then I select following <<a>>
siblings using the condition that the preceding <<b>> sibling must have
the same id. Therefore if the following <<a>> occurs after the following
<<b>> it is not included in the result...
thanks again..
