xslt_set_log - Set the log file to write log messages to

SYNOPSIS

       void xslt_set_log (resource  $xh, [mixed  $log])

DESCRIPTION

	This  function	allows you to set the file in which you want XSLT log messages to, XSLT log messages are different than error messages, in
       that log messages are not actually error messages but rather messages related to the state of the  XSLT	processor.  They  are  useful  for
       debugging XSLT, when something goes wrong.

	By default logging is disabled, in order to enable logging you must first call xslt_set_log(3) with a boolean parameter which enables log-
       ging, then if you want to set the log file to debug to, you must then pass it a string containing the filename.

PARAMETERS

	      o $
		xh -The XSLT processor link identifier, created with xslt_create(3).

	      o $log
		- This parameter is either a boolean value which toggles logging on and off, or a string  containing  the  logfile  in	which  log
		errors too.

RETURN VALUES

	No value is returned.

NOTES

       Note

	      Please note that file:// is needed in front of the path when using Windows.
