List Excludes

[hpguru]

I'm trying to add an exclude to my ad list (help - "BlockList Creation.html") but it doesn't seem to be working. For example there is a "banner" entry in my AdList to catch path elements of the form "*banner*". I want to create an exclusion for "ourbannerlogo". In my AdList I enter

banner
~ourbannerlogo

but this exclude is not matched. If I replace "~ourbannerlogo" with "~*bannerlogo" it matches but this is too general. What am I doing wrong?

what list are you using?

if you provide more info's surely someone here will help you to solve this.

There isn't one. I used that as an example. I'm just playing with results in the test window for now but if you do a Google image search for "bannerlogo" you'll find that the vast majority are not ads. I would like to exclude "(Some_Specific_)bannerlogo" as the need arises but "~*bannerlogo" is just too general and may permit a few ads to get through. "~bannerlogo" will work to exclude say "ourbannerlogo" but it would also exclude "unholyspammersbannerlogo". :-/

The help file gives the example of

*.gif
~*/gamera.gif

So I don't understand why

banner
~ourbannerlogo

won't work.

Here is another example. Seems it should work but it doesn't.

ads.
~downloads.

i was thinking, why not:

~ourbannerlogo
banner

and:

~downloads
ads

i'm thinking that if it first matches ads it stops scanning list so ~downloads can not be found.

i'll do some test when i'll go offline,

That didn't work. Besides the help file mentioned above states

 

quote:You can also add "exclude" lines By prefixing a line with the '~' character. They can be used to limit what a list will match, and are only checked if a regular match is found first in the list. The list will return as true only if none of the exclude lines match.

It depends on how you're calling the list.  unless the check begins with the word you're trying to match, it won't match unless you also add a leading wildcard of some type (which is why the example has "*" in it). Also, if you're calling the list with something like (*$LST(myList)) it won't work like you might expect because as each character is scanned against the list, the exclude will be "false" at a different point from where the match would be true.  It might be easier to see without a list...
 
   *(foo&(^barfoo))

would still match "barfoo" because at the point where "foo" is true "barfoo" is, in fact, false.  Confused yet?  ;-)

No but I need all the help I can get!

Thanks Scott. I'll take that and see what I can come up with. Currently I'm using an exclude list but that is slowing me down too much.
