I'm using Oxygen 15.0 with Saxon PE 9.5.0.2 XSLT 2.
My XSLT is rusty, and I was struggling with the expression of particular
descendant expression. After a number of botched attempts, I cam up with two
versions that seemed to work. (Yes, I will use the ancestor:: axis, but I want
to know what is happening here.)
The following code operates on an xhtml document.
It would help if you posted a minimal but complete document allowing us
to reproduce the problem.
1) <xsl:variable name="table-node" select="//*:table[//*:tr[count(*:td) =
3]][1]"/>
Are you sure that you want
//*:tr
inside of the predicate and not
.//*:tr
?
Your current versions looks at all *:tr elements in the document, not at
the *:tr descendants of the *:table element you are applying the
predicate to.
2) <xsl:variable name="table-ancestors"
select="//*[descendant::node()=$table-node]"/>
You compare the string value of a table element to other nodes, is that
what you want? The ". is $foo" which checks node identity you have below
in 3) seems more meaningful to me.
3) <xsl:variable name="table-parents" select="//*[descendant::node()[. is
$table-node]]"/>
