Take empty lines as separators with the QString::split() function?

[msue]

Don't give up easily :-) and try up to four "". And compare the regexp docu about it. You can click on QRegExp in your code above,

Thanks for your're fostering me...
What is not recognized is actually the "^" symbol... Cause I tried to match it alone and no result was found...

Hi,

^ in regexp means start of the line

[clemmy9]

Well I changed a bit my code as to transform the encoding of my file into utf8 :

@ QFile file("/home/clemence/textes_test/jamaica_out.conll");
if (!file.open(QIODevice::ReadOnly))
LERROR << "cannot open file" << endl;
QTextStream in(&file);
in.setCodec("UTF-8");
while (!file.atEnd()) {
QByteArray text=in.readAll();
QString textString = QString(text);
QRegExp sentenceSeparator("^\n");
QStringList sent= textString.split(sentenceSeparator, QString::KeepEmptyParts);
LDEBUG << " There is " << sent.size() << "sentences " << LENDL;
@

but unless I'm doing it wrong, it's not the point...

Can't you just check if the QString is empty?
I have done something similar with std::string

@ std::ifstream myfile ("file.txt");
if (myfile.is_open())
{
while (getline (myfile,line))
{

        if (line=="")
        {
            raw.push_back(daten);
            data.clear();
        }
        else
        {
            data.push_back(line);
        }

    }
    myfile.close();
    raw.push_back(data);
    data.clear();
}@

In my case every empty line creates a new entry in an vector of an vector.

I have, my Qstring contains my text as expected...

[nnead]

i modified your code sniplet

@ int sent=1;
QFile file("D:\database.txt");
if (!file.open(QIODevice::ReadOnly))
qDebug() << "cannot open file" << endl;
while (!file.atEnd()) {
QByteArray text=file.readLine();
QString textString = QString(text);

    if (textString.size()<3){sent++;}

}
qDebug() << " There is " << sent << "sentences ";@

It counts the right amount of lines for me

[clemmy9]

Thanks but I don't want to count lines but sentences. If you look at my input file at the beginning of this topic page, you can see that there are several lines for 1 sentence. That's why I used the readAll function and the "^$" QRegExp.

[nnead]

Hi by lines i meant sentences, you can just copy&paste the sniplet and see if the number matches your data. For the given example it would compute: "There is 2 sentences".

[clemmy9]

It actually computes the number of line, that is not the number of sentence

[clemmy9]

Okay I've just understood what you meant nnead. I tested your code on data with longer lines so it couldn't work... Thank you :)
