Filtering ads in RSS feeds?

[eclipse]

First of all a BIG warm hello to you all! Is nice to see this forum pick up the pace (yes, i was lurking around for some time now). I even thought I already had an account here, what a surprise I had this morning trying to login!

Now to the real "issue":

Lately I've been getting more and more ads from google in my RSS feeds (feedads and feedads[1-7].googleadservices.com) I guess there's more than 7!
Although there's been some hits from addomains i think it was some cookie thing as the ad was displayed.
There's some odd thing: sometimes the ad doesn't display, but proxo has nothing to do with it (some google problem I guess)
Example:

Code:

The first request (http://feedads.googleadservices.com/~at/..._doivUbE/i) doesn't display anything, the second one DOES (http://feedads.googleadservices.com:80/~...2XFcDw/i).



1) Sidki's set doesn't filter XML "out of the box" right?

So I did my homework and found this:
http://prxbx.com/forums/showthread.php?t...filter+xml
http://prxbx.com/forums/showthread.php?t...filter+xml
http://prxbx.com/forums/showthread.php?tid=1084

And imported z12's version:

Code:

[HTTP headers]
In = TRUE
Out = FALSE
Key = "Content-Type: 5. Filter XML (in)"
Match = "((text/xml|application/xml)*)\0"
Replace = "\0$FILTER(true)"

2) After enabling this filter why doesn't kick in some of the general ad removers?

With my caveman ability managed to rewrite feedads.googleadservices.com -> f.googleadservices.com (whatever!)
Currently it's filtering EVERYTHING, so I need some scope. Do I need to test for Content-type in the pattern section so it doesn't trigger on every page I load and affecting performance?
EXAMPLES VERY WELCOME!

3) AND, everything between <div class="feedflare"> * </div> isn't needed. Can't get this to work properly.


Example RSS feeds with googleadservices:

I'm using Sidki's latest set, Opera 9.63 and Feeddemon for the feed reading.
