Re: [xsl] [string to node]

So, I have thought of <xsl:variable name="a" select="..."/> to get the
value. however, I have to choose depending upon certain conditions,
and hence the <xsl:choose> inside. Also, exsl:node-set() library is
not complete (http://exslt.org/exsl/index.html). If you download this,
the node-set xsl is missing. I had looked at this option earlier.

However, I have just managed to get what I need working using the
inherent, xalan:nodeset() which comes bundled with the Xalan-C
processor.
With Xalan-C one can have a structure like this:

<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"; version="1.0"
                xmlns:xalan="http://xml.apache.org/xalan";
                exclude-result-prefixes="xalan">

.....
....
...
<xsl:if test="count(xalan:nodeset($a)) &lt; 2 >
   .....
</xsl:if>

</xsl:stylesheet>

Cheers!
