copied!<p><strong>Using an <a href="http://www.w3.org/TR/xslt20/" rel="noreferrer">XSLT 2.0</a> processor and the <a href="http://www.w3.org/TR/xpath-functions/#func-collection" rel="noreferrer"><code>collection()</code></a> function this is really easy</strong>.</p> <p>Below is an example using <strong><a href="http://www.saxonica.com/documentation/index/intro.html" rel="noreferrer">Saxon</a></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:param name="pDirName" select="'D:/Temp/xmlFilesDelete'"/> <xsl:template match="/"> <wrap> <xsl:apply-templates select= "collection( concat('file:///', $pDirName, '?select=*.xml;recurse=yes;on-error=ignore' ) )/* "/> </wrap> </xsl:template> <xsl:template match="*"> <xsl:copy-of select="."/> </xsl:template> </xsl:stylesheet> </code></pre> <p>When this transformation is applied on any XML document (not used), it processes all xml files in the file-system subtree starting at the directory, whose value is specified by the global parameter <strong><code>$pDirName</code></strong>. </p> <p><strong>At the time this transformation was applied there were only two xml files</strong> there:</p> <pre><code><apples>3</apples> </code></pre> <p>and</p> <pre><code><oranges>3</oranges> </code></pre> <p><strong>The correct result is produced</strong>:</p> <pre><code><wrap> <apples>3</apples> <oranges>3</oranges> </wrap> </code></pre> <p>This is the simplest example possible that can be constructed. <strong>To fully answer the question, the directory can be specified on the command line invoking Saxon.
