Subject: Re: Regular expression question

I realize you've gotten what is probably the most correct answer,
but here are a couple of alternatives:

str.gsub(/\{/, '<');
str.gsub(/\}/, '>');

or better still

str.gsub(/\{(.*?)\}/, '<\1>');

Which has the advantage of being a more general case, i.e. it will
work on {h1}, {center} or anything else in braces.
