QRegExp : search a pattern that does not contain another pattern

Question

I am trying to search the following pattern : .+$

But this pattern must not contain a  tag.

Given the following example: abba acba adba

If I use the previous pattern, the result is : acba adba

But the good result, which I want is : adba

Because I want disallow a  tag between the two  and  border tags.

So, how can I do that?

I use QRegExp and I code in c++ language.

Thank you in advance for your help,

Floréal.

Your example does only contain two open/close pairs. Not one open/close pair within another open/close pair. Did I misunterstand something or is there something wrong with the example? — Bowdzone, Dec 10 '14 at 09:20

See : QRegExp::setMinimal ( bool minimal )

Just set the QRegExp setMinimal property to true. E.g. :

QRegExp regExp;
regExp.setMiminal(true);
// use your reg exp

This will resolve your query.

You can use a not flag:

QRegExp rx("\\<b\\>[^\\<b\\>]+\\</b\\>");
