expat (the XML parser used in these functions) has support for adding comment
handlers, but that doesn't appear to be hooked into the PHP extension, so you
can't get at that functionality without patching the source of the extension.

If you look in the PHP source, under ext/xml/xml.c you see:

/* Short-term TODO list:
* - Implement XML_ExternalEntityParserCreate()
* - XML_SetCommentHandler
* - XML_SetCdataSectionHandler
* - XML_SetParamEntityParsing
*/

The second one being what you want.
