Re: [xsl] Filtering RSS feed with xsl based on presence of certain words in description

[ac <ac@xxxxxxxxxxxxx>]

Hi,

How about:

<xsl:variable name="keywords" select="('word1', 'word2', 'word3')"/>

<xsl:template match="item[description = $keywords]">
  .. process the item ..
</xsl:template>

<xsl:template match="item">
  .. do nothing ..
</xsl:template>


Cheers,
ac
