how QXmlStreamReader parse QString

hi, all,
I have a string which is the xml structure. and I want to parse it by QXmlStreamReader,
but the QXmlStreamReader want the QIODevice as it's parametre, but I only have the string, so How do I convert the string to QIODevice ,is it use the
QBuffer buff(& myString.toUTF8),
or QTextStream textStream(&myString) and then textStream.device(),
both ways seems don't work , any help ,thanks very much!

QXmlStreamReader can accept a string:

I'm have the same problem here, i have tried using QBuffer,QByteArray and Qstring in different combinations with no succsess :(

below is the different ways that i have tried:

Code:

---

QSting  xml; //with some xml structure
 
QByteArray bArray(xml);
QBuffer buffer;
QBuffer buffer(&bArray)
reader.setDevice(&buffer);
 
//or like this
buffer.setData(xml.toUtf8());
 
//then
buffer.open(QIODevice::ReadOnly)
 
//or this way
reader.addData(xml.toUtf8());
 
//what the heck! this then Grrr
QXmlStreamReader reader(xml);

---

after using "setDevice" or just "addData" etc i do the following:

Code:

---

int ret = reader.readNext();
	while(!reader.atEnd())
	{
		if(reader.isStartElement())
		{
			if(reader.name() == "Application")
				ReadApplicationElement();
			else
				reader.raiseError(QObject::tr("Error"));
		}
		else
			reader.readNext();
	}

---

What am i missing?? it's not the XML because i have tried with QFile and it works that way...
