Desired Output:
<?xml version="1.0" encoding="UTF-8"?>
<urlset xmlns="http://www.sitemaps.org/schemas/sitemap/0.9";>
<url>
<loc>http://www.example.com/first</loc>

<priority>0.90</priority>
<changefreq>daily</changefreq>

<url>
<loc>http://www.example.com/second</loc>
<lastmod>2012-03-16T07:38:42+00:00</lastmod>
<priority>0.60</priority>
<changefreq>weekly</changefreq>
</url>
<loc>http://www.example.com/third</loc>
<lastmod>2012-03-16T08:37:09+00:00</lastmod>
<priority>0.60</priority>
<changefreq>weekly</changefreq>
</url>
</urlset>
The can be done with Muenchian grouping as follows:
<xsl:stylesheet
xmlns:xsl="http://www.w3.org/1999/XSL/Transform";
xmlns:s09="http://www.sitemaps.org/schemas/sitemap/0.9";
exclude-result-prefixes="s09"
version="1.0">
<xsl:output indent="yes"/>
<xsl:strip-space elements="*"/>
<xsl:key name="url-by-loc" match="s09:url" use="s09:loc"/>
<xsl:template match="@* | node()">
<xsl:copy>
<xsl:apply-templates select="@* | node()"/>
</xsl:copy>
</xsl:template>
<xsl:template match="s09:urlset">
<xsl:copy>
<xsl:apply-templates select="s09:url[generate-id() =
generate-id(key('url-by-loc', s09:loc)[1])]"/>
</xsl:copy>
</xsl:template>
</xsl:stylesheet>
