Careful that substring-before(..., ')') will get everything before the 
*first* ')' after the '#'.  So if the XPointer expression has a ')', then 
this would break.  Perhaps you could do:

substring-after(substring(@href, 1, string-length(@href) - 1), '#xpointer(')

so long as you always know that there is exactly one ')' and never anything 
else at the end of the href.
