Remove all link title attributes

Do you want to preserve the images title attribute? If not here is a code that fixes that for you:

add_filter('the_content', 'remove_title_attr');

function remove_title_attr($text) {

    // Get all title="..." tags from the html.
    $result = array();
    preg_match_all('|title="[^"]*"|U', $text, $result);

    // Replace all occurances with an empty string.
    foreach($result[0] as $html_tag) {
        $text = str_replace($html_tag, '', $text);
    }

    return $text;
}

Found it here. It works on c9.io. I believe it will work in your case, too.

Edit 1: This will remove the title attribute from all your posts’ content. Do you want to remove it globally from all elements?
