How bout:

#!perl

open (IN, $in);
open (OUT, ">$out");
select (OUT);
while (<IN>) {
        s/<[^>]*>//g;
        print;
}
close OUT; close IN;
select (STDOUT);


The regex matches a <, then anything NOT a > for unlimted chars, then a >
then and removes it from the line.

Why do I like Perl?  Because "in accordance with Unix theory, it gives you
enough rope to hang yourself with."  - Programming Perl.

Why do I dislike Java?  Becuase "I can't find the object/class called ROPE
that contains the method called HANG." - Shawn.
