    copied!<p>It's not pretty but you can use the xalan:nodeset function to "pre-process" the numbers into a nodeset with an easily sortable expression as described by Jim. </p> <p>This example works for me with Xalan 2.5.1:</p> <pre><code>&lt;?xml version="1.0"?&gt; &lt;xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0" xmlns:xalan="http://xml.apache.org/xalan"&gt; &lt;xsl:output method="xml" indent="yes" /&gt; &lt;xsl:template match="/"&gt; &lt;root&gt; &lt;!-- Create a sort node with a sort expression wrapping each ROW --&gt; &lt;xsl:variable name="nodes"&gt; &lt;xsl:for-each select="/root/ROW"&gt; &lt;xsl:variable name="sort-string"&gt; &lt;xsl:call-template name="create-sort-string"&gt; &lt;xsl:with-param name="sort-string" select="text()" /&gt; &lt;/xsl:call-template&gt; &lt;/xsl:variable&gt; &lt;sort sort-by="{$sort-string}"&gt; &lt;xsl:copy-of select="." /&gt; &lt;/sort&gt; &lt;/xsl:for-each&gt; &lt;/xsl:variable&gt; &lt;!-- Now sort the sort nodes and copy out the ROW elements --&gt; &lt;xsl:for-each select="xalan:nodeset($nodes)/sort"&gt; &lt;xsl:sort select="@sort-by" data-type="text" /&gt; &lt;xsl:copy-of select="*" /&gt; &lt;/xsl:for-each&gt; &lt;/root&gt; &lt;/xsl:template&gt; &lt;xsl:template name="create-sort-string"&gt; &lt;xsl:param name="sort-string" /&gt; &lt;!-- Biggest number at each level --&gt; &lt;xsl:variable name="max-num" select="1000" /&gt; &lt;xsl:choose&gt; &lt;xsl:when test="contains($sort-string, '.')"&gt; &lt;xsl:value-of select="$max-num + number(substring-before($sort-string, '.'))" /&gt; &lt;xsl:call-template name="create-sort-string"&gt; &lt;xsl:with-param name="sort-string" select="substring-after($sort-string, '.')" /&gt; &lt;/xsl:call-template&gt; &lt;/xsl:when&gt; &lt;xsl:otherwise&gt; &lt;xsl:value-of select="concat($max-num + number($sort-string), '0')" /&gt; &lt;/xsl:otherwise&gt; &lt;/xsl:choose&gt; &lt;/xsl:template&gt; </code></pre> <p></p> <p>I personally think writing an extension function would be preferable, but I know that's it's not always an option.</p>
