QtXmlPatterns using QXmlItem to focus in QXmlQuery cannot get results.

Neuxstein

Hi all,

I try to query a node say the following :"/TestRun/Config/Test/PA/Pulse" with the code bellow:
@ QFile* file = new QFile("/home/user/hardwaretest.xml");
qDebug() << file->open(QIODevice::ReadOnly);

QXmlQuery query;

query.setFocus(file);
query.setQuery("/TestRun/Config/Test/PA/Pulse");

QXmlResultItems* results = new QXmlResultItems();
query.evaluateTo(results);

QXmlItem item = results->next();

while(!item.isNull())
{
    if(item.isNode())
    {
      QXmlQuery query2;

      query2.setFocus(item);
       query2.setQuery("./@pulseWidth/string()");

      QXmlResultItems* results2 = new QXmlResultItems();
      query2.evaluateTo(&results2);

      QXmlItem item2 = results2->next();

      while(!item2.isNull())
      {
        if(item2.isAtomicValue())
            qDebug() << item2.toAtomicValue().toString();
        if(item2.isNode())
            qDebug() << "item2 is a node";
        item2 = results2->next();
      }
      delete results2;
    }
  item = results->next();
}

file->close();
delete file;
delete results;@

Here is a part of my xml file :

@<?xml version="1.0" encoding="UTF-8"?>
<TestRun>
<Config>
<Test name="Pulser">
<PA>

<Pulse amplitude="0.1" pulseWidth="0.1" riseTime="10" reverberation="0.04" />
</PA>
<UT>

<Pulse amplitude="0.1" pulseWidth="0.1" riseTime="10" reverberation="0.04" />
</UT>
</Test>
<TestRun>@

I do get the node
@<Pulse amplitude="0.1" pulseWidth="0.1" riseTime="10" reverberation="0.04" />@

on the first query, but the second only return an empty node...

I never were able to get results with QXmlQuery focused on an QXmlItem.

Somebody knows what I do wrong here?
Thank in advance.
