EDIT: Ah, I think I found the problem. Your tool does not show the case sensitive flag as set, while I have cs ="yes' in my regexp.
And in your previous post, you use cs="true", so I am assuming that is what you are expecting.

My version of the undocumented features (such as the attribute cs) is based on the output of Scraper Editor.
It was interesting that while all other attribute used "yes", this one was set to "true"... I thought it was deliberate.

I set up my mind to read through the Scraper Editor thread, to find new hints and features.
The first I have found is the tag include... This will be done by loading functions from included libraries just before the scraping/debugging starts, and dropping them after one closes the debugger.
