We use xsl to validate supplied xml. It outputs useful debugging info when a xml file processed with it fails.

When the attached saxonex.php is run from the cli, the following info is printed to stdout, but it doesn't seem to be able to be captured for use within PHP. I can verify it is not output generated or seen by PHP by wrapping the processor in an ob_start(), ob_end_clean() - the xsl output I require is still displayed, excluding the final line produced by php.

Attached are the files and script I am testing with. The example xml file should fail and produce the following output indicating that the last tag is empty:

# php saxonex.php
