Woops stupid clipboard didn't bring my whitespace across. The example should
look like this:
import maya.OpenMaya as OM
import maya.cmds as cmds
locator1 = cmds.spaceLocator()
mathNode = cmds.createNode("multMatrix")
locator2 = cmds.spaceLocator()
sList = OM.MSelectionList()
sList.add(locator1[0])
sList.add(locator1[0]+".rotateX")
sList.add(mathNode)
sList.add(locator2[0])
sList.add("locatorShape"+locator2[0].lstrip("locator"))
sListAsStrings = []
sList.getSelectionStrings(sListAsStrings)
print "List: %s" % sListAsStrings
iter = OM.MItSelectionList(sList, OM.MFn.kDagNode)
while not iter.isDone():
objectName = []
iter.getStrings(objectName)
if iter.itemType() is not OM.MItSelectionList.kDagSelectionItem:
print "%s is not a valid dagpath. It is item type %s" %
(objectName[0], iter.itemType())
else:
print "%s is a valid dagpath" % objectName[0]
iter.next()
