Regular Expression not working!

[sirop]

bq. Note: The C++ compiler transforms backslashes in strings. To include a \ in a regexp, enter it twice, i.e. \.

I had done that(forgot to mention here) ..still no result!!

Can you pass your code example with a "text to be parsed"?

[sirop]

Try
@QStringList field = str.split(".(?![a-z])");@

Maybe with \.

[jazzco]

This way you are getting a string comparison. If you want the .split function to use a regular expression, you must pass a QRegExp:
@QStringList field = str.split(QRegExp(".(?![a-z])"));@

Yes I I appreciate your help, Sirop. But, I have already tried almost everything before posting here, and unfortunately nothing works. Here's my snippet :-
QString st = "HELLO HOW ARE YOU.a THANK HOW YOU.2ELLO NOT YOU.";
QStringList ql = st.split("\.(?![a-z])");
qDebug()<< ql.at(0);

OUTPUT: "HELLO HOW ARE YOU.a THANK HOW YOU.2ELLO NOT YOU"

jazco let me try this..

yeah jazzco yours works with double backslash! Thanks a ton, jazzco and sirop.

Hi,

Double backslashes are needed because you are still writing a string, so you need escape the backslash properly in order to obtain the correct regexp. You can test and validate regular expressions for QRegExp with the regular expression example from Qt's sources.

Yes. I get that.
