Hi Jennifer, Thanks for the reply. I think I am seeing the light now. With your help and others from the list, I am really getting it now. The FPs I was getting are gone after changing the limit from \w{0,7} to \w{1,7}?. This really makes a huge difference. Thanks again!
Don't feel awkward answering the questions. Know one knows a pet better than the owner! I would like to move away from the previous discussion but still maintain this topic so I removed the previous posts but am maintaining the subject to keep the thread. Hope this is good with those following this thread. So I started experimenting again. Danger Will Robinson! ;) I had the following HTML tag OBFU rule (variant of yours): /(\>|\s)\w{1,5}?\<\/?\s?[\w\s]{6,150}\/?\s?\>\w{1,7}?(\s|\W|\<)/ The thing I started to notice was that it missed OBFU like below (which will wrap a little - the <br> is followed by an EOL). <br> O<f>UR U<RCEN>S Doct<X>ors wi<qk>ll Wri<vlL>te YO<NOsF>U a<WmL> Prescr<yhE>iption<br> Y<jHCe>ou wi<fm>ll ge<nT>t i<n>t NEXT<m>-DAY vi<ZvI>a Fed<YYam>-Ex<br> <br> So I changed the rule to the following: /(\>|\s)\w{1,5}?\<\/?\s?[\w\s]{1,150}\/?\s?\>\w{1,7}?(\s|\W|\<)/ But I started matching the following: <small>Top</small> This came from a legit newsletter. I assume that is why you used [\w\s]{6,150}. I have not found an answer yet, but I have an idea that may work. I think that if I create a rule like below, I might snag it. /\s\w{1,5}?\<\/?\s?[\w\s]{1,150}\/?\s?\>\w{1,7}?(\s|\W)/ It seems that most ham does not include the spaces which break up words. I'll experiment and let you know the results. Thanks again Jennifer. These rules have really tagged a bunch of messages that were at best borderline. A lot of messages would have slipped through without these! --Larry ------------------------------------------------------- This SF.net email is sponsored by: SF.net Giveback Program.
