Firstly, the disable-output-escaping attribute isn't available on
xsl:variable, so you ought to get a syntax error (though some processors are
a bit lax, and just ignore attributes they don't recognize).
Secondly, I don't know the precise specification of xalan:node-set(), but I
would expect that in this case it will give you a document node containing a
single text node whose value is the character string
"<Node><Value>HI</Value></Node>"
I wouldn't expect it to parse that string into XML for you.

into a node set?
Assuming that the xml is valid I guess my only question now is why #1
works and #2 doesn't?
#1 (untested)...works ...with <.>
<xsl:variable name="rtf">
<Node><Value>HI</Value></Node>
</xsl:variable>
<xsl:copy-of select="xalan:nodeset($rtf)/child::*/Value" />
#2 (untested)...doesn't works...with < ...>
<xsl:variable name="rtf">
<Node><Value>HI</Value></Node>
</xsl:variable>
<xsl:variable name="rtf2" select="xalan:nodeset($rtf)"
disable-output-escaping="yes"/>
<xsl:copy-of select="($rtf2)/child::*/Value"/>
I sincerely appreciate the discussion and help with this, Michael.

to some kind of extension (in Saxon you could use
saxon:parse()). I can't
tell from your description which is likely to be more
convenient in your
case. One approach would be to do it in a URIResolver
triggered by the
document() function, but I don't know if that's appropriate
in Xalan-C.

Thanks for the reply, Michael! The XSLT version is 1.0
and I'm using
Xalan v1.5 or v1.6 of the C/C++ for this specific application
solution. I'm testing the raw transform itself via
JEdit using the
lastest build of the XSLT plugin for Xalan Java (not sure
what version
that is).
However, I would like to avoid any disk i/o or uri
specification for
this solution due to high message volume and fault
tolerance. Since I
recieve the xml filter specification within a Xerces Dom
Document as
passed from a server I would like to take the filter xml
contents and
pass it into an existing stylesheet as xml contents
<Filter>....</Filter> itself. This is all happening on the client
side in mememory and the only way that I can think of
adhering to this
requirement is parsing the filtered xml node xml contents into an
existing stylesheet as a parameter.
Thoughts?

The way you pass parameters to a stylesheet depends on the
API of the XSLT
processor that you are using. Many will allow you to pass a
DOM Document
node.
If you're using Saxon from the command line, the parameter
+Filter=filter.xml causes the file filter.xml to be
parsed, and the
resulting document (root) node becomes the value of the
parameter.
Another approach is to pass the URI as the stylesheet
parameter, and then
call document() from within the stylesheet.

Subject: [xsl] Converting <xml> StyleSheet param contents

HI all, can somebody tell me how I can pass <xml>
contents into a
stylesheet param and then convert that <xml> contents
into a nodeset?
Stylesheet: ( Filter=<Node><Whatever/></Node> )
...
<xsl:param name="Filter" select="string('NULL')" />
<xsl:copy-of select="$Filter"/>
...
Output:
<Node><Whatever/></Node>
However, I want to turn the xml contents above into a
node set that I
can later use in the transform. Is that possible (is
there something
other than using CDATA)?
Any information would be greatly appreciated.
