Excluding CF and Js Commenting tags

What do you need the number of lines of code for? You may not need to exclude the comments.

Comments, if well motivated, are an integral part of the code! In fact, in most software engineering and project management analyses, the required value of the number of Source Lines of Code (SLOC) actually includes comment lines!

Did you mean:

For CF commenting tags :  <cfset filecontent=rereplacenocase(filecontent,"<![^>]*>","","all")>

Javascript /* */ are trickier, since both * and / are valid symbols within comments. This should work:

<cfset filecontent = REReplace(filecontent, "/\*.*\*/", "", "ALL")>

Don't forget the "//" style Javascript comments, which you can probably match with something like:

<cfset filecontent = REReplace(filecontent, "//.*(\r\n|\n)", "", "ALL")>

(It is seldom a good idea to use .* in regular expressions--you often get more than you bargained for. But these examples are just for illustration.)
