Line wrapping...  "What a concept."

In my PHP XML parsing 
tutorial, http://www.analysisandsolutions.com/code/phpxml.htm,
I use the following preg to clean out those nasty characters:

#  Remove all non-visible characters except SP, TAB, LF and CR.
$Contents = preg_replace('/[^\x20-\x7E\x09\x0A\x0D]/', "\n", $Contents);
