[xsl] Use XSLT to check a bunch of XHTML files for well-formedness?

["Roger L Costello costello@xxxxxxxxx" <xsl-list-service@xxxxxxxxxxxxxxxxxxxxxx>]

Hi Folks,

I have a folder containing a large number of XHTML files.

I want to know: for each file, is it well-formed?

What is the easiest and fastest way to see if each file is well-formed?

My thinking has been to create a super-simple XSLT program:

<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform";
                          xmlns:xs="http://www.w3.org/2001/XMLSchema";
                         exclude-result-prefixes="xs"
                         version="2.0">

    <xsl:template match="*" />

</xsl:stylesheet>

and then run the XSLT on each XHTML file.

I have a command file (.bat file) that loops over each XHTML file and runs the
XSLT:

for %%i in (xhtml\*.xhtml) do (
echo %%i
java -jar saxon-ee-10.1.jar %%i -xsl:test-well-formedness.xsl
-o:well-formedness\%%i
)

That works, but it's pretty slow.

So, I looked into compiling my XSLT program:

On this SAXON web page it talks about Compiling a Stylesheet:

https://www.saxonica.com/html/documentation/using-xsl/compiling.html

On the page it says:

	In simple cases, you can exploit the ability to process an
	entire directory of source files using a single invocation
	of the Transform command on the command line.

That sounds perfect.

But the web page, as far as I can tell, doesn't describe how to "use the
Transform command to process an entire directory of source files."

What do you recommend?
