Hello to all A RegExp beginner's question again. I cannot find a way to search for a regexp that matches everything except of one certain string. The problem is: author = {somename}, editor = {}, title = {sometitle}, subtitle = {}, series = {}, url = {} I want to find a regexp that matches every line with empty {} except of the "subtitle line". I've come that far: ^ \<[^s].* = {},* But this one also excludes the "series line", of course. I was thinking of \<[^s][^u] but this doesn't work, since, then, the initial s of "subtitle" is matched again. What is the syntax for find .* except of the string "subtitle"? I didn't recognize this in the Lisp info. Thanks for help Sven
