Asunto: RE: [xsl] How can I get context node in this complex expresion?
(current( ) didn't work)
Can't be done in a single XPath 1.0 expression - you need to build up the
result of the XPath expression in a series of variables declared at the XSLT
level.
In XPath 2.0 you use the "for" expression to bind variables at any level of
nesting, for example,
<xsl:apply-templates
select="ROW[for $x in COB_ID return $x =
$cob_rowset[CXC_CAD_ID=key('cad_key_ori',
$cob_rowset[COB_ID = $x]/CXC_CAD_ID)/CAD_REL_ID]/COB_ID]">
I'm assuming a ROW has only one COB_ID, otherwise these aren't equivalent.
