xml.etree.ElementTree.iselement()

tree and elements

Checks whether an object looks like a tree element: True for Element and its subclasses, False for strings and ElementTree.

Syntax

ET.iselement(element)

The check is duck-typed: True for any object with a tag attribute, not only for Element instances. An ElementTree wrapper does not count as an element; call getroot() first. For a strict type check use isinstance(x, ET.Element).

Examples

import xml.etree.ElementTree as ET
root = ET.fromstring('<a/>')
print(ET.iselement(root), ET.iselement('<a/>'))  # → True False
print(ET.iselement(ET.ElementTree(root)))  # → False
class Fake:
    tag = 'x'
print(ET.iselement(Fake()))  # → True
