(style|id|class)=".*?"
is your basic regexp for that in PCRE, which I think is what Notetab
uses. Not too difficult.
It reads 'style or id or class followed by =" and then everything up to
the next "'

That's very difficult for the program to know-- there are a vast number
of ways to match a given bit of highlighted text, how is the program
supposed to know which of them you want?

Honestly it's easier just to read the manual. The Python docs have a
very clear explanation of PCRE syntax.
