推荐答案

也许是这样?

import xml.dom.minidom

def getParentObjectNode(node):
    while node.parentNode:
        node = node.parentNode
        if node.nodeName == "Object":
            return node

xml = xml.dom.minidom.parse("C:\\myxml.xml")
for shirtNode in xml.getElementsByTagName("Object"):
    if shirtNode.getAttribute("label") == "shirt":
        break

shirtParentObject = getParentObjectNode(shirtNode)
print(shirtParentObject.getAttribute("label"))
shirtParentParentObject = getParentObjectNode(shirtParentObject)
print(shirtParentParentObject.getAttribute("label"))
