numeric comparison (inequality)

I want to check for a number that is greater then 499... the
whole
strring looks like this "(500 seconds)"

I wrote this reg ex in two parts to check and it works, but
there must
be a more elegant way to do it?


\([5-9]\d{2,}.*seconds\)|\([1-4]\d{3,}.*seconds\)

thanks in advance.

Jason

It's better to factor out the opening parenthesis from the
front of the
alternation(for matching efficiency). and the non-greedy
form .*? might
be better than the greedy one .* in your pattern. But I
guess you need
\s* here.  so,
another way of your pattern can be written
as(untested): 

    \((?:[5-9]|[1-9]\d+)\d\d\s*seconds\)
