I'm trying to write a plugin for Feedwordpress that filters html from the incoming feeds. So far I have managed to hook it to the right place, but the function completely wipes all content (and it seems to cause issues with the Feedwordpress plugin). Where am I going wrong here?

add_filter(
    /*hook=*/ 'syndicated_item_content',
    /*function=*/ 'fwp_rss_regex',
    /*order=*/ 10,
    /*arguments=*/ 1
);

function fwp_rss_regex ($post) {
    $content = $post->post_content();   
    $content = preg_replace('\<[^\>]*\>', '', $content);
    return $content;
}

Fixed it with:

function fwp_rss_regex ($content) {
$content = preg_replace('/\<[^\>]*\>/i','',$content);
return $content;
}

This solved the problem: 1) Because $content was the item I wanted I wanted to pass through fwp_rss_regex, 2) Because I fixed my preg_replace with /______/i , and 3) I realised $content = $post->post_content(); was either a superfluous (though maybe valid) command, or was it doing nothing in at all.
