Ah, I overread the shortcode - mea culpa.
@look at the source: Github strips the part after return print in the comment in my code lines above :)
@get_* and the_*: absolutely. A public API with "template tags" is always appreciated. If I'd use your plugin, i'd write one just to avoid the need to add the shortcode to every post I publish. Just check for the active plugin and then execute right before the comments loop.
And one thing that would be kool as well is a hook instead of a post list definition inside wpse32725_catch_iframe().
Did you ever submit this to the WordPress plugin repo?
I tried your code, but accessing http://localhost/mysite/iframe giving 404 , Can you please give me some idea, how I can make it work ?
UPDATE working for http://localhost/mysite/?iframe=true.
There is a shortcode there to stick the embed in a page. Maybe I should mimic the WP core: function to fetch the stuff and another to echo it out?
What do you mean by this?
// look at the source in the following line: input gets stripped in comments
