QXmlQuery and Xpath : cannot extract neither the node's text nor the parameter’s value

[hisoft]

Hi,

I'm trying to extract some data from an xml content. So i used QXmlQuery and wrote the code below (in Qt5). The problems are :

1. If i try to extract text1 (so a node's text, see line 32), the code returns me the whole node : <value>text1</value>

=> Question 1 : how to get only text1 ?

2. If i try to extract x1 (so a parameter's value, see line 35), the code returns me an error :
   Error SENR0001 in file:///C:/work/tests/build-TestXMLParser-Desktop-Debug/debug/TestXMLParser.exe, at line 1, column 1: Attribute param can't be serialized because it appears at the top level.

=> Question 2 : What i'm doing wrong ?

Here is the code :
@
#include <QApplication>

#include <QFile>
#include <QDebug>
#include <QXmlQuery>
#include <QXmlSerializer>
#include <QXmlFormatter>
#include <QBuffer>

int main(int argc, char *argv[])
{
QApplication a(argc, argv);

QString xmlContent =
        "<nodes>"
            "<node1 param='x1'>"
                "<value>text1</value>"
            "</node1>"
            "<node2 param='x2'>"
                "<value>text2</value>"
            "</node2>"
        "</nodes>";

QBuffer device;
device.setData(QByteArray(xmlContent.toUtf8().constData()));
device.open(QIODevice::ReadOnly);

QXmlQuery query;
query.bindVariable("inputDocument", &device);

// Extracting "text1"
query.setQuery(QString("doc($inputDocument)/nodes/node1/value[text()]"));

// Exracting "x1"
//query.setQuery(QString("doc($inputDocument)/nodes/node1/@param"));

// Output value
QByteArray outArray;
QBuffer buffer(&outArray);
buffer.open(QIODevice::ReadWrite);

QXmlSerializer serializer(query, &buffer);
query.evaluateTo(&serializer);

buffer.close();
qWarning() << "Exracted value : " << QString::fromUtf8(outArray.constData());

exit(0);

return a.exec(&#41;;

}
