I am using the information on QRegExp from http://doc.qt.io/qt-4.8/qregexp.html and am having a bit of a problem with negative lookaheads. It seems that it is ignoring them when I use regular expressions on my news filter.
Here is the code I am using:
But it is including the words from the negative expression in my news filter. Am I missing something?
Did you try the non-part
only to see if it works?
I use this
You're right. My negative lookahead wasn't working and the one you mention works great. But when I add the words I want included it doesn't return the desired results.
I've tried both
and I'm not getting the results I'm looking for. Is there a particular order or placement for the expressions?
I shortly tested this positive:
That didn't do it for me. Here is what I got to work in case anybody needs to use this in the future:
Hmm, I seem to be having problem with the word boundary \b. Is anyone else having problems with that escape character?
For instance, (?!.*(?:words|\bI\b|do|not|want)).*$ is different from (?!.*(?:words|I|do|not|want)).*$ in that the second one will match any word with the letter I in it but the first will only match the whole word I.
The behaviour is correct. See f.e. this description.
What are you trying to achieve?
I guess it's \B you need.
