If you're using Saxon 7.8 then
(a) you should be using Saxon 8.1.1
(b) you are using XSLT 2.0 and therefore don't need the xx:node-set()
function
(c) the Saxon namespace should be http://saxon.sf.net/
The most likely explanation for the "casting empty sequence" error is that
there is no @dc:date attribute - certainly, you haven't given us any
information about it, nor did you mention the dc namespace.

Subject: [xsl] Sorting RTF
Hi all,
Apologies in advance if this is an FAQ (and I don't see how
it couldn't
be), but several days of searching the web, usenet, and mailing lists
have not turned up a solution.
I'm using Saxon 7.8 with these namespaces:
xmlns:exsl="http://exslt.org/common";
xmlns:saxon="http://icl.com/saxon";
extension-element-prefixes="saxon exsl"
Here's what I want to do:
<xsl:variable name="items">
<xsl:apply-templates select="*"/>
</xsl:variable>
<xsl:for-each select="exsl:node-set($items)/*">
<xsl:sort select="xs:dateTime(@dc:date)" order="descending"/>
<xsl:copy-of select="."/>
</xsl:for-each>
Saxon responds to this with this error on the for-each line:
"An empty sequence is not allowed as the value in 'cast as'
expression".
I know $items isn't empty because if I replace the for-each with a
copy-of, I get the expected nodes. I have tried setting my
stylesheet's
version to 1.0, 1.1, and 2.0, and I have also tried these:
select="$items"
select="$items/*"
select="exsl:node-set($items)"
select="saxon:node-set($items)"
select="saxon:node-set($items)/*"
The last two give me this error:
"No function found matching saxon:node-set with one argument"
Which makes me think that maybe xmlns:saxon is wrong, but I
haven't seen
any others in my searching.
Any help would be appreciated.
