This variable isn't used.

This variable is only used once, on the line below so really  no point 
in havin it, as mentioned before $foo will be a document node with a 
text node child that is a sequence of 0 and 1.

So it will only be equal to 1 if all but the last value in the loop 
above gave 1 ir if $foo is 0000000000000000000001  But it seems a pretty 
strange thing to be testing.

As a wild guess, perhaps you didn't want any variable at all and wanted 
all of the above replaced by


 <xsl:if test="(partiotion/files/file[@name=bxxb or name=bxyb or 
name=basdb or  b&b&b&.. )/
       data/(contains(elements/elementA '1234) or 
contains(elements/package/id '55) or contains(elements/category/id, 
'67)" or contains(b&b&b&b&.))">
 do something
</xsl:if>
