copied!<p><strong>Here are two different solutions</strong>: a simple one and a more complicated one that produces only the unique countries:</p> <p>.1. Get all <code>Country</code> elements:</p> <pre><code><xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"> <xsl:output omit-xml-declaration="yes" indent="yes"/> <xsl:template match="node()|@*"> <xsl:copy> <xsl:apply-templates select="node()|@*"/> </xsl:copy> </xsl:template> <xsl:template match="*[not(self::Country)]"> <xsl:apply-templates select="*"/> </xsl:template> </xsl:stylesheet> </code></pre> <p><strong>when this transformation is applied on the provided XML document, the wanted, correct result is produced</strong>:</p> <pre><code><Country>Germany</Country> <Country>Mexico</Country> </code></pre> <p>.2. <strong>Find all unique countries</strong>:</p> <pre><code><xsl:stylesheet version="2.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"> <xsl:output omit-xml-declaration="yes" indent="yes"/> <xsl:key name="kCountryByVal" match="Country" use="."/> <xsl:template match="/"> <xsl:copy-of select= "/*/*/Country[generate-id() = generate-id(key('kCountryByVal',.)[1]) ] "/> </xsl:template> </xsl:stylesheet> </code></pre> <p><strong>when this transformation is applied on any XML document with the structure of the provided document where some <code>Country</code> elements may have the same value, only one <code>Country</code> element for each different value is produced</strong>.</p> <p>With the provided XML document we still get the same result:</p> <pre><code><Country>Germany</Country> <Country>Mexico</Country> </code></pre>
