Is this possible in XSLT

I would like to be able to check a series items in a list against items in
another. Selecting the parent item of the second list if it contains all the
items in the list (but it may contain more) for example

to check

<item id=a/>
<item id=b/>

the following would satisfy the criteria

<pa>
 <item id=a/>
 <item id=b/>
 <item id=c/>
</pa>

I immagine being able to create a dom xml fragment containing the first list
to be able to do this - I don't know if this really a good idea or not.

All hints clues or advice appreciated! Thanks
