I solved this problem years ago:

1) Have a standard error handler which can be invoked using trigger_error();
I call mine 'errorHandler'.

2) Create an alternative error handler for XML/XSL processing in PHP 5. I
call mine 'XML_errorHandler'

function XML_errorHandler ($errno, $errstr, $errfile, $errline,
$errcontext)
// deal with errors from XML or XSL functions.
{
// pass these details to the standard error handler
errorHandler (E_USER_ERROR, $errstr, $errfile, $errline,
$errcontext);
} // XML_errorHandler

3) Just before performing and XML/XSL processing switch to the alternative
error handler:

set_error_handler('XML_errorHandler');

4) Don't forget to switch back again afterwards:

set_error_handler('errorHandler');

All this code can be downloaded from my website in my sample application at
