How can I get context node in this complex expresion?

xsl expresion
Hi all...

This is the real case I have:

<xsl:apply-templates
select="ROW[COB_ID=$cob_rowset[CXC_CAD_ID=key('cad_key_ori',
$cob_rowset[COB_ID = 2]/CXC_CAD_ID)/CAD_REL_ID]/COB_ID]">

where:
	$cob_rowset : a nodeset that I assign previously. It is correctly assigned.
	'cad_key_ori' a key that is correctly defined as well.

That expresion works the way I want (showing some records according to the
predicate). But that is a particular case. The general case is replacing the
'2' above for the node COB_ID whose parent is ROW. For instance, I tried:

<xsl:apply-templates
select="ROW[COB_ID=$cob_rowset[CXC_CAD_ID=key('cad_key_ori',
$cob_rowset[COB_ID = current()/COB_ID]/CXC_CAD_ID)/CAD_REL_ID]/COB_ID]">

The call to current() didn't work (it didn't show anything and I know that
'COB_ID=2' is present in ROW nodeset). I think it is because current() is
pointing to $cob_rowset context node.

Any help would be greatly appreciated.

Thanks
Jaime
