Guys,

I thought this thing was not working with XSL 1.0 since the variable would
only contain text, and not a node-set.

Even in XSLT 1.0, the $myxml variable declared as above would be bound to a node set. All is fine; no extension element is necessary.

This is the difference between

<xsl:variable name="myxml" select="document('somefile.xml')"/>

and

<xsl:variable name="myxml">
  <xsl:copy-of select="document('somefile.xml')"/>
</xsl:variable>

The second variable is bound to a result tree fragment (a *copy* of the original node set).

Could you please elaborate a little bit more on that point. Just reading the
EXSLT doc was not enough for me to understand the use of the new node-set
function.

The function allows you to turn any RTF, such as the copy just described, into an honest-to-goodness node set. So it won't make any difference how it's declared. It'll also let you do things like

<xsl:variable name="myRTF">
  <xsl:apply-templates select="document('somefile.xml')"/>
</xsl:variable>

<xsl:variable name="myNodeSet" select="exslt:node-set($myRTF)"/>

and then process the nodes in the variable as if they were a source document (even though they are themselves the result of a transform).

This allows chaining or "pipelining" of transforms within a single stylesheet process. Powerful, if sometimes a bit tricky to debug....

Shouldn't this thread have a subject line?

Cheers,
Wendell
