copied!<p>EDIT</p> <p>Upon reading your post again, I think the original version of my answer (below) is not it.</p> <p>You <em>have</em> a list already - your variable declaration selects a node-set of all <code><country></code> nodes that are children of <code><Request></code> (a node-set is the XSLT equivalent of an array/a list):</p> <pre><code><xsl:variable name="$country" select="Request/country" > </code></pre> <p>But the point is, you don't even <em>need</em> that list as a separate variable; all you need is:</p> <pre><code><xsl:when test="Request[country=$country]"></xsl:when> </code></pre> <p>Where <code>Request[country=$country]</code> reads as "Within <code><Request></code>, look at every <code><country></code> and select it if it is equal to <code>$country</code>." When the expression returns a non-empty node-set, <code>$country</code> is in the list.</p> <p>Which is, in fact, what Rubens Farias said from the start. :)</p> <hr> <p>Original answer, kept for the record.</p> <p>If by "list" you mean a comma-separated string of tokens:</p> <pre><code> <xsl:variable name="countries" select="'EG, KSA, UAE, AG'" /> <xsl:variable name="country" select="'KSA'" /> <xsl:choose>  <xsl:when test=" contains( concat(', ', normalize-space($countries), ', ') concat(', ', $country, ', ') ) "> <xsl:text>IN</xsl:text> </xsl:when> <xsl:otherwise> <xsl:text>OUT</xsl:text> </xsl:otherwise> </xsl:choose> </code></pre> <hr>
