Get All Nodes inside an Xpresso Tag?

bentraje

Hi,

Is there a way to get all nodes inside the xpresso tag?
I tried checking the documentation and the forum and I don't get any relevant hits.

It's for the workaround on this thread (https://developers.maxon.net/forum/topic/12246/how-do-i-return-the-connected-port-from-the-input-port/1)

Regards,
Ben

Ah my bad. It's just the same for objects in object manager.
Here is the code for reference:

import c4d 

def GetAllNodes(gvNode=None, nodeList=None):
        if nodeList is None:
            nodeList = list()
            gvNode = nodemaster.GetRoot()

        while gvNode:
            nodeList.append(gvNode)
            GetAllNodes(gvNode.GetDown(), nodeList)
            gvNode = gvNode.GetNext()

        if len(nodeList) > 1: 
            nodeList = nodeList[1:] # Remove the Xgroup
            
        return nodeList

geo_obj = doc.SearchObject("Cube")
exp_tag = geo_obj.GetTag(1001149) #Get Expresso
nodemaster = exp_tag.GetNodeMaster()
node_list = GetAllNodes()

Hi yes, GvNode are BaseList2D and GeListNode, like material, object, tags.
There is the same discussion going on, so you may find it interesting Issue collecting all the shaders in a material.
