i would like to read all XML files of a directory. To this end I use the entryList function of QDir.
I have seen that you precise a filter to display files only, but is there a way to be more precise and display only .xml documents ?
For the moment I use the following instruction:
QStringList entries = dir.entryList(QDir::Files);

Use that function:
QDir::entryList ( const QStringList & nameFilters, Filters filters = NoFilter, SortFlags sort = NoSort ) const
Simple example:
QDir dir(yourPath);
QStringList filters;
filters << "*.xml"; //append your xml filter. You can add other filters here
foreach ( QString file, dir.entryList(filters, QDir::Files) )
// do wathever with *.xml files
Have look as well at http://doc.trolltech.com/4.6/qdir.html#setNameFilters

How do I get the current file name and path within the foreach loop? I need to draw information from each one and put it into a vector.
QDir dir(path);
QStringList filters;
filters << "*.txt";
foreach(QString file, dir.entryList(filters, QDir::Files)){
QFile mine(/*file path? */);
mine.open(QIODevice::ReadOnly);
// stuff here
}

For file name and path use QFileInfo class.

For file name and path use QFileInfo class.
Exactly. Loop over entryInfoList() to get these.
