[SOLVED] QTextStream problem !

issam

hi,

I am using this piece of code to validate an XML file against an XML scheam. Once the XML file is valide, I use QTextStream to read the file content as QString then display it on the terminal :

@
// open file
QFile file(filename);
if(!file.open(QIODevice::ReadOnly | QIODevice::Text))
{
qDebug() << "Cannot open file ";
return;
}

// validate file against XML schema
QXmlSchemaValidator validator(schema);

if(!validator.validate(&file, QUrl::fromLocalFile(file.fileName())))
{
file.close();
qDebug() << "instance document is invalid";
return;
}

//display
QTextStream textstream(&file);
QString xmlContent = textstream.readAll();
qDebug()<<xmlContent;
file.close();
@

But, the qDebug() function display an empty string ("") !

Any idea ?

thanks in advance.

Hi,

A shot in the dark but, since the validator must read the file in order to do the validation, the current file position might be at the end.

Try to add

@file.seek(0);@

before creating the QTextStream.

Also since you are reading all the file anyway, why not read it all in a QByteArray, then validate that array ?
