In the "second answer", we are looking for a string match that starts with and does not have "-" in between it. So it will fail, for example, with nested comments, or comments that contain a dash for some reason, or perhaps other formats. However, it is probable that it will work for most people, most of the time. If you are one that uses "-" as a convention in comments, you will have to change the code. Regarding why .* fails, I don't know exactly. traditionally the "." character doesn't work past lines and the "*" character is "greedy" (you'll have to look that up, because this is not a regular expression forum). So, the .* should not work at all for this purpose. However, since WebDNA's grep implementation is not POSIX standard, and is a hybrid of sorts, it appeared to work in my quick test that I did before I originally posted... parsing more than one line. A further test showed that it does not work consistently. A yet further test showed that it does not appear to be "capacity limit" thing. Frankly, my real answer is neither "solution". I don't think regular expressions (in WebDNA's grep, or POSIX regex) is the "sure-fire" answer to this problem. However, one could probably build a more thorough regex call (I'd probably call the POSIX regex with [shell] via sed (find/replace) rather than use WebDNA's hybrid grep which is not yet well documented) that would be more versatile and robust, but I think the real answer probably lies in a tried and tested module/function somewhere..probably callable from WebDNA's [SHELL] or what-have-you. Though WebDNA could indeed be the solution for such a problem, *existing* modules are usually the result of many years of work by more than one person, which makes it worth checking out the third party solution. For a solution in WebDNA, I guess I'd start building a parser.. perhaps using listwords and other tools. However, it could be a long rode to get something solid. Since it is not easily done, WSC may look into this to see if something could be done with removehtml... [removehtml comments] or something. This may be worth the effort because it is something that comes up in our line of work occasionally. However, it would fall back on the priority list quite a ways.
