It's going to work, even if it kills me

Hi Chaps,

I'm still trying to pass a list of keywords in as a parameter and then 
search an xml file for any of those words and return a html formatted 
header list.

An example XML file is:
<articles>
	<article ID="article1">
		<date>
      Tue Jun 19 10:38:02 BST 2001
        </date>
		<detail>
      Tim has bought a Land Rover, for better or for worse.  There will 
be no more tellings-off from the Better Half about wet dogs in good car.
    </detail>
		<title>
      Tim Buys a Land Rover
    </title>
	</article>
	<article ID="article2">
		<date>    
      Tue Jun 19 10:44:28 BST 2001
    </date>
		<detail>
      Nice car but nothing compaired to Tim's new Landy.
    </detail>
		<title>
      Kirsten Buys a Vauxhall
    </title>
	</article>
</articles>



The XSL snip I'm playing with is:
..snip...
	<xsl:template match="/">
		<xsl:apply-templates select="articles">
                <xsl:with-param name="keywords">
			<xsl:value-of select="$keywords"/>
               </xsl:with-param>
		</xsl:apply-templates>
	</xsl:template>
	
	<xsl:template match="articles">
    		<xsl:param name="keywords"/>
		<xsl:variable name="keywordfrag">
			<xsl:call-template name="keylist">
				<xsl:with-param name="keywords">
					<xsl:value-of 
select="$keywords"/>
				</xsl:with-param>
			</xsl:call-template>
		</xsl:variable>
		
		<xsl:for-each select="article[contains(translate
(detail, $vLower, $vUpper),translate(xalan:evaluate($keywordfrag)//*, 
$vLower, $vUpper))]">
			......do stuff......
		</xsl:for-each>
	</xsl:template>
	
<xsl:template name="keylist">
    <xsl:param name="keywords"/>
    <xsl:variable name="key" 
        select="substring-before($keywords,' ')"/>
    <xsl:choose>
        <xsl:when test="string-length($key) > 0">
            <keyword><xsl:value-of select="$key"/></keyword>
            <xsl:call-template name="keylist">
                <xsl:with-param 
             name="keywords"><xsl:value-of 
             select="substring-after($keywords,' ')"/>
               </xsl:with-param>
            </xsl:call-template>
       </xsl:when>
        <xsl:otherwise>
             <keyword><xsl:value-of select="$keywords"/></keyword>
        </xsl:otherwise>
    </xsl:choose>
</xsl:template>
.....snip......

The result of this is that it finds all articles because the call to 
the keylist template does not return an xml fragment, just a list of 
keywords without the spaces.

Idea's would be wonderful.

Thanks,
Tim.
