Regex question

[OneSolution]

I am trying to write a regular expression that will match all the exceptions
generated in my application log file. I have done it as such:

\bjava\.\w+\.\w +Exception:

However, there are two exceptions that I know will occur and I don't care to
catch them. So I need to modify the above regular expression to ignore the
two exceptions that will get generated.

I don't know how to do that. Your help will be much appreciated.

Thanks,
Z

You're gonna get jumped on for crossposting, but here's a duplicate of
my post to you in c.l.java.*:

You could use negated lookbehind:

\bjava\.\w+\.\w +(?<!(Type1|Typ e2))Exception

I *think* that's the right lookbehind syntax...

I don't see _cross_ posting. So, I guess it was _multi_ posting --
which is more egregious.

I have a lot of problems with exception handling in regex. Perhpas I
don’t know how to do it...

So I do a pre-process, which changes the exception to something else.
Then I run my regular regex,
and then change the exceptions back to their original condition.
Tedious, but it works.
