Help With Expression

Howdy,

Regex is new to me and trying to parse an NT Event log for
email count.


The following is an example of text in the NT Event log:
Expected eMails > actual : iEmailsExpected=36,
numEmailMessages=35

I would like to get a match if I get
"numEmailMessages=19"  or LESS in
the NT Event.

I've come up with the following expression, but the logic
is backwards,
it comes up with emails 20 or MORE, not 19 or less.

numEmailMessages.(2|3[0-9])

Any help will be appreciated.

Thanks,
Dan Foxley

If you check only positive numbers without leading zero(like
01, 02),
then you may use:

    numEmailMessages=1?\d

this will match '2' or '30' or '31' or '32' or ....
'39'. If you want
20-39, then:

  [23]\d

But if you want to match all integers greater than 19, then:

  [2-9]\d|(?!0\d)\d{3,}

\d is a shortcut of [0-9].  (?!0\d) construct is to make
sure no
leading zero.

Good luck,
Xicheng
