IOS-XR NED device module stored at position 3

[Abdel el Anazi]

Hi,

I have some question which I am struggling with, I have to read the device NED type from the device module. Almost all NEDs returns with position 0 from the keys the correct NED type except IOS-XR NED the position of the NED type is not 0 but 3 which confuses my python code: 

Here is an overview of the device modules:

This is what I read in Python:

def get_device_type(root, device):

   modules = root.devices.device[device].module.keys()

   return str(modules[0])

Is there a reason why IOS-XR has interfaces instead of device ned type in position 0?

How do I get around this without modifying the code?

You cant without modifying your code. The module list isn't an "ordered-by user" list so there is not guarantee to what order the list will be returned in.
