Help with regular expression

[marco.minerva]

Hi!

I have the following regular expression, that matches any word with
number and letter:

[[:alnum:]]+-?[[:alnum:]/@\\.#&]*'?

Now I must modify it so that also the word with a "_" inside are
accepted. For example:

As_for
From_now_on
For_example

Can you help me?
Thanks in advance.

This is really off-topic here, since there are no regex in (the current)
C++ standard, you should ask these kinds of questions in a forum for the
library you used for regexes. Having said that I think you can get it to
do what you want with one of the following (I'm no expert at regex and I
don't recognize the flavour so I give no guarantees):

[[:alnum:]]+(-|_)?[[:alnum:]/@\\.#&]*'?

[[:alnum:]]+[-_]?[[:alnum:]/@\\.#&]*'?

TR1 does include include a regex library, and FAQ 5.9 says questions
are on-topic if they can be answered by looking at the standard or
"planned extensions and adjustments" to it. So I'd say both the
question and your answer are on-topic.

As does C++0x.
