xsl variables and node-sets

[Simon]

Hi,

I would like to use <xsl:variable> and <xsl:choose> to dynamically set a
node-set to a variable.
Something like:

<xsl:variable name="MyVar">
<xsl:choose>
<xsl:when test="$MyVar2='0'">
Here I want to select a node set from the source xml document
</xsl:when>
<xsltherwise>
Here I want to select a different node set from the source xml
document
</xsltherwise>
</xsl:choose>
</xsl:variable>


Does anyone know how I can do this?


Thanks.

Simon
