wp-includes/kses.php: wp_kses_attr_parse() | Finds all attributes of an HTML element. |
Builds an attribute list from string containing attributes.
Does not modify input. May return "evil" output. In case of unexpected input, returns false instead of stripping things.
Based on wp_kses_hair()
but does not return a multi-dimensional array.
(string) (Required) Attribute list from HTML element to closing HTML element tag.
(array|bool) List of attributes found in $attr. Returns false on failure.
