I still have one problem. I can't get it to search on more
than one keyword.
I think this is because I'm using the contains() function like this:
contains({element content}, $keywords)
Any ideas?
You could do
contains({element content}, $keyword1) and contains({element content},
$keyword2)
but of course that would only work if the number of keywords was fixed in
advance
(unlikely).
Otherwise you'd probably have to define a recursive template to parse
$keyword.
Something like: (untested)
<xsl:template name="contains-keywords">
<xsl:param name="str" select="''" />
<xsl:param name="keywords" select="''" />
<!-- Return '1' if the given string contains all keywords
(space-separated strings); otherwise '0'. -->
<xsl:choose>
<xsl:when test="$str = ''">1</xsl:when>
<xsl:otherwise>
<xsl:variable name="first-keyword" select="substring-before($keywords, '
')" />
<xsl:choose>
<xsl:when test="contains($str, $first-keyword)">
<xsl:call-template name="contains-keywords">
<xsl:with-param name="str" select="$str" />
<xsl:with-param name="keywords"
select="substring-after($keywords, ' ')" />
</xsl:call-template>
</xsl:when>
<xsl:otherwise>0</xsl:otherwise>
</xsl:choose>
</xsl:otherwise>
</xsl:choose>
</xsl:template>
