How to validate special characters in QString

[Indrajeet]

Hi All

I have QStringList<QString> i want to check if any of the QString has special character in it.
how to do this?

[andre]

Define "special characters"?
Anyway, I guess QRegExp would come to mind, but you will have to do it per QString. No way do it for the whole QStringList in one go.

Special characters like ! @ # $ % ^ & * ( ) _ +

Ya i want to do it per QString only.

[andre]

So... did you look at [[doc:QRegExp]]?

Try this:

@
QString str = "123345!@#$%^&()_+";
int icount = str.count(QRegExp("[!@#$%^&()_+]"));
@

will return 10

You are aware that QString supports "unicode":http://unicode.org/?

Are you sure there are no problematic characters in the non-ASCII range of the unicode table?
