Automation script for DOM instances: retrieving instances by guid

I looked into the documentation, but it's not clear how to retrieve an instance using a guid as an input.
Next I'd also like to retrieve a field value from that instance object.

I already have a DomHelper object.  So far so good.
Any ideas on how to go about the rest?

Hi Jeroen,

Let me quickly give you few pseudo code snippets (C# blocks):

GET DOM INSTANCE

// Retrieve the DomInstance
var helper = new DomHelper(engine.SendSLNetMessages, "MODULE ID");
var filter = DomInstanceExposers.Id.Equal(<DOM INSTANCE ID>);
var domInstance = helper.DomInstances.Read(filter).FirstOrDefault();

GET FIELD OF DOM INSTANCE (follow up on code block above)

 
var instanceField = domInstance.Sections?.FirstOrDefault().GetFieldValueById(< DOM DESCRIPTOR ID >);
object instanceValue = instanceField?.Value.Value;

Note: I assume it is better to for-loop the sections list.

Hope this helps you further
