Basic RegEx question

All,
If I have this:

$xmlstr = str_replace("&", "%amp;%", $xmlstr);

How can I use use a regex expression (if it is needed) to do the replace
UNLESS the string contains A&E (you know, the TV channel).
Thanks.

$xmlstr =
stristr($xmlstr, 'A&E')
? 'A&E'
: str_replace("&", "%amp;%", $xmlstr);
