escaping PHP's closing tags

Hi -- I'm trying to use a string of XML data which includes the use of the <?xml ?> tags. I've noticed that my editor (BBEdit) shows that \?> will escape the tag so that PHP does not treat it as a true "close the PHP code" tag, but was hoping that someone here could give me an official ruling. There is no reference to escaping the ?> tag on the man page (currently) that I could find, or in the annotations. Erik ---- Erik Price Web Developer Temp Media Lab, H.H. Brown pricee@hhbrown.com
