Thank you Ken, very clear.

I'll give it a whirl and get back, likely tomorrow.

Hello,
I currently have a template that successfully processes a single xml file.

I would like to iterate through a folder of XML source documents and

The XSLT 2 concept you are looking for is "collections".  There are no
standardized URI strings to represent a collection, but Saxon's URI
convention is straightforward.

You don't show us your data format, but your example could be modified along
the lines of:


My template that successfully processes my source file is

<?xml version="1.0" encoding="utf-8"?>
<xsl:stylesheet version="2.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform";>

<xsl:template match="Account">


You now want to do the logic at the start of processing, so match="/".


<html>
      <body>
              <h2>LogEntries</h2>
         <table border="1">
           <tr bgcolor="#9acd32">
                <th>Column1</th>
                <th>Column2</th>
           </tr>


At this point you now want to walk all XML files and, I assume, process the
document element named "Account" in each one as a row:

 <xsl:for-each select="collection('./?select=*.xml')/Account">


           <tr>
                <td>
                  <xsl:value-of select="Firstname"/>
                </td>
                <td>
                  <xsl:value-of select="Lastname"/>
              </td>
           </tr>


 </xsl:for-each>


         </table>
      </body>
</html>
</xsl:template>

</xsl:stylesheet>

The output I want is basically a single html file
that includes a table with 2 columns

Column1                    Column2
Firstname1      Lastname1      (info from file1)
Firstname2      Lastname2      (info from file2)
Firstname3      Lastname3      (info from file3)


etc...

Not clear this is possible.


It certainly is.


I could code it in Java / C# to iterate
the docs but kinda feels like it should be possible with just XSLT
Any insight or reading would be appreciated.


I hope the above helps.  Check the Saxon documentation for all of the
features of the URI for collections.
