Get collection context in XQuery

[ricardo queiros]

Hi,
I'm a newbie in XQuery and i appreciate a answer to this doubt.

I store several XML documents in a Native XML Database (eXist).
In my organisation i have several collections with several XML files that
share the same structure. The following structure defines 2 collections A
and B. The collection A have 2 XML files and the collection B one.

A
  - 1.xml
  - 2.xml
B
  - 3.xml

I have his XQuery file:

FOR $x in collection("A","B")
WHERE ...
RETURN ?

If, for example, only the 2.xml and 3.xml were evaluate for TRUE in the
WHERE clause, i want to obtain the following XML data:

<RESULTS>
<A>2.xml<A>
<B>3.xml</B>
</RESULTS>

What should i put in the RETURN clause?

I can also have collections inside other collections...

Thanks in advance
