I have a file in which I am searching for the letter "i" (actually a bit more general than that, arbitrary regular expressions could occur) as long as it does not occur inside an expression that matches \\.+?\b (something started by a backslash and including the word that follows).
More concrete example, I have the string "\sin(i)" and I want to match the argument, but not the i in \sin. Can this be achieved by combining the regular expressions? I do not know the right terminology involved, therefore my searching on the Internet has not led to any results. I can achieve something like this by searching for all i and then throwing away those i that are inside such expressions. I am now just wondering if these two steps can be combined into one.
