I admit it... I´m lost without you...

Code:
        Dim In1 As String = ""
        Dim InN1 As String = ""
        Dim x As New XmlDocument()
        x.Load("http://192.168.178.158:8088/api")

        Dim nodes As XmlNodeList = x.DocumentElement.SelectNodes("/vmix/inputs/input[2]")
        For Each node As XmlNode In nodes
            In1 = x.SelectSingleNode("//overlay[4]/@key").InnerText
        Next

        Dim nodes2 As XmlNodeList = x.DocumentElement.SelectNodes("/vmix/inputs")
        For Each node As XmlNode In nodes2
            InN1 = x.SelectSingleNode("//input[@key 'In1']/@number").InnerText
        Next


Purpose is to generate a "Red Light" frame in a custom Multi View (Blank with defined MV layout) independant
of which Input is set in the different Multi View Previews.

That for I first get the input key of the used MV overlay
check, works
then to compare with "SelectSingleNode("//active").InnerText" I need the input number, or am I wrong...
When I use the key directly e.g. 6a971275-a9...aso I easily get the corresponding number...

The rest is clear and working (RL indicating active input in multi view preview)

This node selection and "for each" loop aren't doing anything. They can be omitted.

Also, you probably shouldn't use a subscript of 4, but rather search for the overlay with the attribute "number" equal to 4.

Then your last line, trying to select the input, you want to use the number attribute, not the key attribute, like:

Code:
        Dim In1 As String = ""
        Dim InN1 As String = ""
        Dim x As New XmlDocument()
        x.Load("http://192.168.178.158:8088/api")

        In1 = x.SelectSingleNode("/vmix/overlays/overlay[@number='4']").InnerText
        InN1 = x.SelectSingleNode($"/vmix/inputs/input[@number='{In1}']").InnerText


The dollar sign at the start of the string tells the interpreter to replace variables in {} brackets with their actual value.

So that cleans up your existing code. I wasn't able to understand exactly what you're trying to do. But I hope this helps you in the right direction.

Yes, the contents of the "active" element is the input number. If you want to select that input, you would do something along the lines of:

Code:
    Dim active as String = x.SelectSingleNode("/vmix/active").InnerText
    Dim activeInput as XmlNode = x.SelectSingleNode($"/vmix/inputs/input[@number='{active}']")

Thanks Kross,

I had to do some little adjustments:

Code:
In1 = x.SelectSingleNode("//overlay[4]/@key").InnerText 
InN1 = x.SelectSingleNode($"//input[@key='{In1}']/@number").InnerText
active = x.SelectSingleNode("//active").InnerText 


but your hint with the "String Announcement" and syntax solved the issue.
With the gathered info I can control the "redlight" in the MV Overlay (GTZIP Title)
