 Yes it's in perl and this is why you'll not use it :-)

 For example these *complex* regexp can't parse this valid document

pigeon% cat aa.html
<!DOCTYPE HTML PUBLIC "-//IETF//DTD HTML//EN">
<HTML>
<HEAD>
 <TITLE>aa</TITLE>
</HEAD>
<BODY>

Numbers 2<1

</BODY>
</HTML>
pigeon% 

 There are 2 errors in this script
  * he want to validate an HTML document and a regexp is not the right tool
for this 
  * it try to separate comment from the rest of the document, i.e. the
biggest error is here

#########################################################
# first we'll shoot all the <!-- comments -->

 Never, never use it :-)))
