Re: regular expression

That's because '.' doesn't match newline by default.
To get it to,
you need to add the /m flag. (You also need to have
more than the one
line in the string, of course).

However, * is greedy, which means that given this
text:

Here is some [b]bold text[/b], and here is [b]some
more bold
text[/b]

Your regex will match all the way from the first [b]
to the last [/b],
rather than just to the first [/b]. You can prevent
that by using the
non-greedy qualifier ?, which goes after the *. Also,
I would use %r
instead of /.../ just to avoid one of those nasty
backslashes. :)

That great explanation and code worked like a champ.
Many thanks!
