xml property and get method missing in QtQml.XmlListModel

I am currently porting my application from 5.15 to 6.2.1.

It uses the xml attribute of the QtQuick XmlListModel, binded to a C++ QString.

Unfortunately, the xml attribute is no more available.

By the way, my current workaround is to create a QTemporaryFile and target this local file in the source attribute. Do you have a better idea ?

Second issue, the get method is not available int the QtQml.XmlListModel.
How can I access an item ?

Porting from QtQuick XmlListModel seems very hard
