So let me pose a simple example. The following xml document is our main document, which I still don't have the terminology for. It might look like: <data> <foo>1</foo> <foo>3</foo> <foo>5</foo> <foo>2</foo> <foo>99</foo> </data> Lets say our XSLT creates a global variable "foo_test" and it imports an external data source which looks like: <foo_test> <foo>3</foo> <foo>99</foo> </test_foo> Will the following expression work: <xsl:apply-templates select="data/foo = $foo_test//foo"/> Resulting in a match on: foo = 3; and foo = 4 Now, let do the reverse of this and match on all $foot_test foo elements so we have: <xsl:apply-templates select="$foo_test//foo" mode="my_external_foo"/> And we have the template: <xsl:template match="foo" mode="my_external_foo"> <!-- AT THIS POINT.. HOW DO WE REFER BACK TO MAIN XML SOURCE??? --> <!-- mabye, but isn't /data/foo out of context??? --> <xsl:for-each select="/data/foo"> <xsl:if test=".=current()/."> <!-- I'M ASSUMING WE NEVER MAKE IT HERE --> </xsl:if> </xsl:for-each> </xsl:template> On Thu, 31 Mar 2005 20:55:11 +0100, Michael Kay <mike@xxxxxxxxxxxx> wrote: > > I am discovering such...
