David,
Here is a quick adaption of some code I use that bundles a list of
strings into
a NodeSet of text nodes. It makes for quick XSL processing since they are
just a list of text nodes, there is minimal XPath processing.

<xsl:template match="foo">
<xsl:variable name="myStrings" select="myNS:getStrings()"/>
If there are no strings, NULL is an easy test.
<xsl:if test="$myStrings">
<xsl:for-each select="$myStrings">
The current context is the current string in the list
</xsl:for-each>
</xsl:if>
</xsl:template>
public NodeSet getStrings()
{
try
{
NodeSet resultSet = new NodSet();
Document lDoc = null;
Iterator i = stringList():
// You need to create a new document here so you can generate nodes.
// At least this is the easiest way I have found...
if (i.hasNext()) lDoc = getDocBuilder().newDocument();
while(i.hasNext())
{
String name = (String) i.next();
resultSet.addNode(lDoc.createTextNode(name));
}
return resultSet;
}
catch(Exception e)
{
return null;
}

I may be jumping the gun on this, but I'm trying to figure out how I can
write a Java extension function that returns a list of objects (list of
strings, being regexp group values), and how to process that list in a
stylesheet. I don't see exactly how to do this from the Xalan
documentation.
I'm investigating this because I think I can't use the EXSLT
regexp:match function in WebLogic running JDK 1.4.2 (the EXSLT docs seem
to say this, and it fails when I run it in Stylus Studio).
