Get an ordered list in lxml objectify

Question

If I have an ordered list in XML

<Boa>
    <Channels>
        <Channel name="Red"/>
        <Channel name="Green"/>
        <Channel name="Blue" />
    </Channels>
</Boa>

This code

from lxml import objectify

Boa = objectify.parse(self.xml).getroot()

only gets me

Boa.Channels.Channel

with a single entry for Channel.

How do I get this as an ordered list in lxml objectify? I'm also fine with changing my XML markup if there's something that lxml expects to automatically do the conversion.

this might help... https://stackoverflow.com/questions/39390653/getting-contents-of-an-lxml-objectify-comment — Any Moose, Aug 17 '18 at 18:27

objectify is a bit weird as it tries to map xml to python objects and this is not 100% match so it has to compromise.

Boa.Channels.Channel is the first Channel

>>> Boa.Channels.Channel.get('name')
'Red'

But at the same time it can also work as a list of Channels:

>>> Boa.Channels.Channel[0].get('name')
'Red'
>>> Boa.Channels.Channel[1].get('name')
'Green'
>>> Boa.Channels.Channel[2].get('name')
'Blue'
>>> [c.get('name') for c in Boa.Channels.Channel]
['Red', 'Green', 'Blue']
