Remove \n from QString

[arturs]

Hi

I have a string with 3 lines.

"ABC"
"ABC"
"ABC"

I want to remove second line.
I can remove all characters in the line but still the line there is.

"ABC"
""
"ABC"

I know in second line there is "\n"

I tried to use remove("\n") but It does not work.

So I need help with the problem.

Regards
Artur

I would use QString::split("\n") to created a QStringList of all of the lines. Then you can keep/omit any specific line number or based on QString contents, etc.

You can remove the blank line by replacing a sequence of two newlines with one newline, see QString::replace().
You could have a look at QString::section() also.

Does

QString result = value.remove(QChar('\0'));
//or
QString result = value.remove(QChar(QChar::Null));

QString result = value.remove(QChar('\0'));
//or
QString result = value.remove(QChar(QChar::Null));
