Thanks Bea, I figured that could be done, but then I need to list every possible role. I'd much rather send the parameter list as a whole to the function and let that look for the variables it is coded for. The function the param list being passed to supplied by a component. I'm trying to do this in one request, not two, but I could split it and have a model specific for each component. But I'd rather not do that.
Perhaps there is a way to define the XmlRole for ParamList to be passed as a model itself to a function, then I can take ParamList as a model itself? ----- Original Message ---- From: "[email protected]" <[email protected]> To: [email protected] Cc: [email protected] Sent: Tue, April 12, 2011 10:24:33 PM Subject: Re: [Qt-qml] Parsing model Roles in functions Hi Jason, On 13/04/2011, at 10:21 AM, ext Jason H wrote: > I have: > XmlListModel{ > id: instanceModel > source: "getNextInstanceXml.php" > XmlRole{name:"paramList";query:"instance/paramList"} > } > > Where paramList looks like: > <paramList> > <param name="gradientStart" value="#000000"/> > <param name="gradientStop" value="#FFFFFF"/> > </paramList> The gradientStart and gradientStop values won't be placed into the model unless XmlRole objects are specified for them, since the model won't know the structure of the data that is supposed to be retrieved. I'd suggest something like this, which creates an XmlRole for each value: XmlListModel{ id: instanceModel source: "getNextInstanceXml.php" query: "/paramList" XmlRole { name:"gradientStart"; query:"param[1]/@value/string()" } XmlRole { name:"gradientStop"; query:"param[2]/@value/string()" } } Now if you examine instanceModel.get(0) it will look like: { "gradientStart": "#000000", "gradientStop": "#FFFFFF" } regards, Bea _______________________________________________ Qt-qml mailing list [email protected] http://lists.qt.nokia.com/mailman/listinfo/qt-qml
