Is there a way to return multiple variables from one XPATH request via the TCP API? I would like to return all attributes from a specific input.

Right. So, would the request be
/vmix/inputs/input1/attributes::*
? I have tried a few commands that seemed as though they should return multiple values but I can only get 1 value returned per request. My issues could also be a node socket issue. This is my first experience with XPATH, thanks for the help.

Could you be more specific pls. What exactly do you want to retrieve , why with one request , .... more info is always helpful to get proper answers

try /vmix/inputs/input[1]

I would like to retrieve the full list of attributes for a specific input node, ex:

<input key="cf0d1391-5d9b-40c8-a3f7-32687e05e249" number="1" type="GT" title="Text Middle Centre.gtzip" shortTitle="Text Middle Centre.gtzip" state="Running" position="0" duration="0" loop="False" selectedIndex="0">

Which I would assume would look something like this

key="cf0d1391-5d9b-40c8-a3f7-32687e05e249"
number="1"
type="GT"
title="Text Middle Centre.gtzip"
shortTitle="Text Middle Centre.gtzip"
state="Running"
position="0"
duration="0"
loop="False"
selectedIndex="0"

What I'm actually trying to return is the key, position, and duration of a specific input. Because of the async/listener design of the socket connection, the call does not actually return anything, rather a separate listener is triggered with response data from vmix. It would make things much easier if there was some form of id/key in that response. If request A is made and then B is made immediately after, there is the (slight) possibility of that response B returns before response A...correct? Is there another method of consuming TCP APIs without using sockets?

I have tried /vmix/inputs/input[1], which returns the inner text, title, of the node. Also, thank you for your help doggy

My suspicion is the response function from vmix will not multiple return values.

XMLTEXT /vmix/inputs/input[1]/attribute::*

=> Returns the key only, which is the first listed attribute in the node

XMLTEXT /vmix/inputs/input[1]/@key | /vmix/inputs/input[1]/@duration

=> Also returns the key only
