[SOLVED] QTextStream problem !
-
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 ?
