I have a text file and I would like to compose a regular expression that matches lines containing stringB but not preceded by a line containing string A. I thought one of these might do it:
\(stringA.*\n\)\@<!.*stringB \(stringA.*\n\)\@<!\(.*stringB\) The \@<! was *intended* to ensure a non-match with stringA in the preceding line. However, they highlight the same lines that are highlighted by the opposite regular expressions: \(stringA.*\n\)\@<=.*stringB \(stringA.*\n\)\@<=\(.*stringB\) With a little pondering, it is obvious why. The first .* matches any set of characters, so even if stringA exists in the preceding line, you can always find some portion of the line that doesn't match \(stringA.*\n\). Is there a way to achieve the search described in above? -- -- You received this message from the "vim_use" maillist. Do not top-post! Type your reply below the text you are replying to.
