I often encounter this obstacle.
When I extract data from an URL, and I wish, for instance, to do it like this:
 
Cases[url, {XMLElement[
    "th", {___}, {_, XMLElement["span", {___}, {mo_}], _}], __, 
   XMLElement["td", {___, "id" -> XXX}, {E_}], ___} :> {mo, 
   E}, \[Infinity]]
but, instead of "XXX" I would like to say any string which ends with "priorSettle".
Is it possible? or "XXX" can only be the exact string?
