Using regex to delete part of an html string with given start and end

I read all the regex posts first, before starting this post.

I need to process a large string of html from a generated page, removing some navigation elements; I can add comments as placeholders and markers as needed before generating.

I've attempted to replace the string starting with the inserted comment "<!-- SOBs -->" and ending with "<!-- EOBs -->" but I am failing. I assume it is not something as simple as:

tempString=tempString.replace(/<!-- SoBs -->.*<!-- EoBs -->/gi, " ");
