Check all node types from a given full path

[yann19]

Hi all,

What is the best way that I can break apart and check all the nodes within a given node's full path?

I am trying to check the list of nodes within the path, and should the node/path fulfills a certain node type, it will stop iterating and store that selection..

So far I have tried the following:

for node in set(selections):

    node_split = node.split('|')

    split_len = len(node_split)

    for num in range(split_len):
        # I need to use +2, if using a +1,  a "|" will be returned...

        num = num + 2

        item = "|" + "|".join(node_split[1:num])

        if cmds.nodeType(item) == "customType":

            print item

It seems to work for my cause but wondering if there is a better way to deal with this?

For this my preference would be using PyMel doing something like this

import pymel.core as pm

selections = pm.ls(sl=True)

for node in set(selections):

    allParents = node.getAllParents()

    print allParents

Hope that helps!

Possible to do it not without the use of pymel?

Assuming your selections list are proper full paths, what about something like this:

selections = [

'|path|to|my|node',

]

for node in set(selections):

item = node

while item:

print item

item = item.rsplit('|', 1)[0]

Thank you all, I chanced upon a method and compiled the following code:

def node_type_iteration(path_lists):

    for path in set(path_lists):

        current_object = cmds.listRelatives(path, parent = True, fullPath = True ) or []

        while current_object:

            # Set the condition here...

            if cmds.nodeType(current_object[0]) == "customType":

                return current_object[0]

            else:

                current_object = cmds.listRelatives( current_object, parent = True, fullPath = True )

        return None

If I understand the goal, then something like this might work.

from maya import cmds
cmds.listRelatives("|group1", type="nurbsCurve", allDescendents=True)

If there’s a nurbsCurve on any path starting with |group1, then this would return it.

Test scene

cmds.file(new=True, force=True)
circle = cmds.circle()
cube = cmds.polyCube()
cmds.select(circle + cube)
group = cmds.group()

found = cmds.listRelatives(group, type="nurbsCurve", allDescendents=True)
assert found[0] == cmds.listRelatives(circle[0], shapes=True)[0]
