Indeed I do believe that these files make up the TOC.
Good luck in finding any way to sort which is what.
Why do you need to determine which of the files points to video? This seems something that is much better suited to using the RoboHelp UI to accomplish. I'm guessing there is some reason you can't accomplish it using the RoboHelp UI?
Ahhh, yes I did see that other post where you want some sort of a "dynamic" type link.
Wasn't that the thread where you want all sorts of code added to the hyperlink so that you can track stuff like when it was clicked and what product was being used and all sorts of other stuff and code added in?
One thing that seems like it should work would be for your links to be grabbed from the software. Then you should be able to add TOC pages that point to external links. And I would think it would be as simple as pasting the links into the TOC.
And if that failed for whatever reason, I'm thinking another approach would involve "redirect" type topics. In those topics you configure a behind the scenes meta refresh tag to point wherever you want to land.
I note that neither of these solutions is remotely "dynamic" and building things "on the fly". Nor am I saying it's an impossible achievement. It's just problematic from the aspect of trying to accomplish it within the RoboHelp framework.
Yes, the other post was 'tracking' related (who is clicking what within our help topics). We do utilize redirects to some degree. Table of content pages have links to videos / pdf's and those links utilize the redirect URLs (not sure if that's correct term) associated with those external video / pdf resources. And the subset of topics in help that link up to help buttons in the product have redirects such that the help buttons in product call up the topic using variables including the redirect (in that case, the product constructs the URL and captures customer ID from the product).
You're last comment is helpful in that it and the other post's reply validate my original thought (...problematic to accomplish within RH framework."). I've passed along the Google Analytics and RH Server thoughts from the other post to my coworkers.
Thanks for the added perspective.
