Eregi_replace for font tags?!?

Hi all I would like to know if anyone on this list has a possible solution for replacing FONT tags in HTML being submitted to a site. My idea was to use eregi_replace ... but how do I tell eregi_replace to take a string that starts with '<font' and ends with '>' and replace it. This is a variable string of course because of the input and needs to work differently for different inputs. This is for the use of stylesheets.... thus <font class instead of all others.
