You can do it with a regular expression. Usually, you’d need the ‘m’ modifier, for multiline, and the ‘s’ modifier, for dotall. Reference here:

http://www.regular-expressions.info/modifiers.html

However, the dotall modifier does not exist in javascript, so I usually go for a character class “[\x00-\xff]”. This regexp replace should do the trick:

resultString = yourInputString.replace(/(<\/html&gT;)[\x00-\xff]*/m, "$1");
