Processes an HTML attribute value and strips dangerous protocols from URLs.
$string: The string with the attribute value.
$decode: (deprecated) Whether to decode entities in the $string. Set to FALSE if the $string is in plain text, TRUE otherwise. Defaults to TRUE. This parameter is deprecated and will be removed in Drupal 8. To process a plain-text URI, call drupal_strip_dangerous_protocols() or check_url() instead.
Cleaned up and HTML-escaped version of $string.
function filter_xss_bad_protocol($string, $decode = TRUE) {
// Get the plain text representation of the attribute value (i.e. its meaning).
// @todo Remove the $decode parameter in Drupal 8, and always assume an HTML
// string that needs decoding.
