XSLT Transform multiple files from subdirectory

Question

I have created a XSLT file that can transform a single XML file. However, I have several hundred directories with multiple xml files. Is there a way in XSLT to transform all the

Answer 1

Here is probably the simplest example how to process all the xml files in a file system subtree (using the collection() function as implemented in Saxon):

<xsl:stylesheet version="2.0"
    xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
    xmlns:xs="http://www.w3.org/2001/XMLSchema">
    <xsl:output omit-xml-declaration="yes" indent="yes"/>

 <xsl:template match="node()|@*" mode="inFile">
     <xsl:copy>
       <xsl:apply-templates mode="inFile" select="node()|@*"/>
     </xsl:copy>
 </xsl:template>

 <xsl:template match="/">
   <xsl:apply-templates mode="inFile" select=
   "collection('file:///C:/temp?select=*.xml;recurse=yes')"/>
 </xsl:template>
</xsl:stylesheet>

When applied on any XML document (not used, ignored), this transformation applies the identity rule to every XML document contained in any of the *.xml files in the C:/Temp subtree of the file system.

To do more neaningful processing, one needs to override the identity template -- in the inFile mode.

In your specific case I believe you can simply replace:

            <xsl:apply-templates select="/testResults/result/tables/table[14]">     

with

            <xsl:apply-templates select="./testResults/result/tables/table[14]">    

and this applies the desired templates on the nodes selected off the current (document) node.

I just wanted to add a lightweight version of Dimitre's excellent answer. If you have <foo> documents (root node) sitting in a directory, and a working XSLT program for <foo>, simply make your top-level template like this:

<xsl:template match="/">
    <xsl:apply-templates select="collection($my_url)/foo"/>
</xsl:template>

That's assuming you want the URL as a parameter, <xsl:param name="my_url"/>, specified on the command line.
