Methods and systems are provided for automatically correcting escaping functions in a module of page rendering code. The method includes: providing an HTML escaping schema and a script escaping schema; identifying a first character sequence having a first escaping function; determining whether the first character sequence is coded in HTML or coded as a scripted element; correcting the first escaping function using the HTML escaping schema if the first character sequence is coded in HTML; and correcting the first escaping function using the script escaping schema if the first character sequence is coded as a scripted element.
