Qt XQuery到QStringList

Question

我想用QtXmlQuery從XML中提取一些數據。我想把它放到一個QStringList中。我嘗試以下方法：

QByteArray in = "this is where my xml lives"; 
QBuffer received; 
received.setData(in); 
received.open(QIODevice::ReadOnly); 

QXmlQuery query; 
query.bindVariable("data", &received); 
query.setQuery(NAMESPACE //contains definition of the t namespace 
       "doc($data)//t:service/t:serviceID/text()"); 

QBuffer outb; 
outb.open(QIODevice::ReadWrite); 
QXmlSerializer s(query, &outb); 
query.evaluateTo(&s); 

qDebug() << "buffer" << outb.data(); //This works perfectly! 

QStringList * queryResult = new QStringList(); 
query.evaluateTo(queryResult); 

qDebug() << "string list" << *queryResult; //This gives me no output! 

正如你所看到的，一切正常，當我通過QXmlSerializer的輸出發送到Q緩衝器......但我什麼也沒得到，當我嘗試使用QStringList中。

嘗試使用string()而不是text()，它應該工作。
