This could very well possibly be a bug with Sablot-0.82 
Submitting it to both parties.  I am not sure what is 
causing the problems.  I can send the xsl file in 
question, and possibly the xml involved as it was Dom 
generated, I can also send the php code involved - it will 
contain all of the Dom calls that built the xml.

	Apache-1.3.20
	Sablot-0.82

Thank you for taking the time to report a problem with PHP.
Unfortunately your version of PHP is too old -- the problem
might already be fixed. Please download a new PHP
version from http://www.php.net/downloads.php

If you are able to reproduce the bug with one of the latest
versions of PHP, please change the PHP version on this bug report
to the version you tested and change the status back to "Open".
Again, thank you for your continued support of PHP.
