I use an auto blogging plugin that allows me aggregate RSS feeds from certain sites to fill the gap in my blog in times I don't post in, the idea that posts are injected with ads like AdSense URLs with random dynamic links but usually starts with certain URLS, here is a code snippet:

The idea that all injected tags include "*feedsportal.com", how can I select the whole tag line that includes this term and replace it or delete it in WordPress?
Thanks!
If you want to remove all tags containing the keyword feedsportal.com you can try something like this..
// Replace all matches
$str = preg_replace("/\<a.*?feedsportal\.com.*?\>.*?\<\/a\>/is","",$str);
// Collect matches
preg_match_all("/\<a.*?feedsportal\.com.*?\>.*?\<\/a\>/is",$str,$matches);
// Show matches
print "<pre>";
print_r($matches);
print "</pre>";
