Hello All. I'll be the first to admit that I know zip about regular expressions. In some of the groups there are these huge posts which seem to contain random headers. I'd usually just reject the poster but unfortunately they're using a generic username that would filter out too many posts. So...I'm hoping there's some kind of regular expression I could employ. Ill give an example of the post:

Topic: 645000a7ab8cbbbe86203a5ff1fb97aa[001/104] - "22d79fa0b128555468ab375611e092eb943e91f8b4c10229b06c0b5dcd0be627.0" yEnc
Poster: Yenc@power-post.org (Yenc-PP-A&A)
Group: alt.binaries.hdtv.x264
Message ID example: 1354564952.50075.1@eu.news.astraweb.com

Thanks for any help.

^[a-f0-9]{25,}\[[\d/]+\][\s-]+"[a-f0-9]{35,}[.][a-z0-9]{1,4}" yenc

I wouldn't know where to begin explaining this without direct questions.

Have fun.

Are there any new thoughts on filtering out this type of garbage? I've tried the supplied string and it doesn't work for the newer garbage strings.

Is there an app where I can enter the string I want to filter and it builds the correct RE string?

Thanks

If you Ctrl-R some of these files, you might be able to see what's in them.

"[A-Z0-9]{30}"

Should match these.

Yes, thanks. This does catch quite a few. Some others have one or more hyphens in them and it misses those.

Thanks

You can add hyphens to that too.

"[A-Z0-9\-]{30}"

Maybe this one. I haven't tested that it works.

Thanks....let me try it.

"[A-Z0-9\-]{30}"

Quade, this works very well for filtering out a lot of the header garbage....thanks for the tip!
