Maybe i'm wrong but it seems that this question has not been previously solved yet:

There is some iframe inside post content and I want to get rid of that iframe when the rss feeds are generated. To generate rss feeds, I'm showing full post content.

I started looking at strip_tags() but it does pretty much the opposite: strip everything unless the desired tags.

I'm wondering that maybe there is some hook and some wordpress-y form of solving this issue.

I know I should do something like this:

function rss_noiframe($content) {
    global $post;
    // filter out iframe here
    return $content;

add_filter('the_excerpt_rss', 'rss_noiframe');
add_filter('the_content_feed', 'rss_noiframe');

But I'm lost at this point. Any ideas?

On demand by EAmann, here is some example code that isnt modified at all (it still appears in the feed, in fact):

<iframe src="http://somedomain.net/path/to/frame" frameborder="0" scrolling="no" width="500" height="375"></iframe>

What is adding the iframe? Is it a plugin, a shortcode, manually entered in the HTML editor? – EAMann Jan 16 '13 at 17:50
Manually entered :) – versvs Jan 16 '13 at 17:55

One potential option is to use preg_replace to do a regex match on your content and replace the iframe with empty space.

So this function:

function rss_noiframe($content) {
    $content = preg_replace( '/<iframe(.*)\/iframe>/is', '', $content );

    return $content;

add_filter('the_excerpt_rss', 'rss_noiframe');
add_filter('the_content_feed', 'rss_noiframe');

Should automatically convert any instances of <iframe src=...>...</iframe> to a blank.

thanks, i will try this :) i'm not that skilled with regex and couldnt come up with a solution myself :) – versvs Jan 16 '13 at 18:53
It didnt work, it leaves a completely cleared rss :S – versvs Jan 16 '13 at 19:46
Can you edit your answer to include some example HTML that has the iframe? All of my tests of the above code worked just fine ... – EAMann Jan 16 '13 at 19:55
i added a sample iframe, thanks again :-) – versvs Jan 16 '13 at 20:40
Ok, sorry, it was my fault... Your code works indeed! I was calling the_content() to do further processing (add thumbnail) and that was overriding your regex. – versvs Jan 16 '13 at 21:31
