Subject: RE: [xsl] Data not displaying in HTML table...generated from XML From: "Michael Kay" <mhk@xxxxxxxxx> Date: Tue, 28 Oct 2003 23:43:29 -0000 |
A path expression beginning with "/" selects the root node of the
document containing the context node. In your template with
match="metadata", the expression "/page-links" will not select anything.
Define a global variable <xsl:variable name="root" select="/"/> and then
use $root/page-links, which will get you back to the principal source
document whatever you are currently processing.
But if you do that, then this:
<xsl:template match="metadata">
<xsl:for-each select="$root/page-links/page-link">
<xsl:apply-templates select="document(@filename)/metadata"/>
</xsl:for-each>
is going to give you an infinite loop. I don't actually know what you
are trying to achieve here.
