I'm using the xml.etree.ElementTree module to create an XML document with Python 3.1 from another structured document.
What ElementTree function can I use that returns the index of an existing sub element?

To read an XML file using ElementTree, firstly, we import the ElementTree class found inside xml library, under the name ET (common convension). Then passed the filename of the xml file to the ElementTree. parse() method, to enable parsing of our xml file. Then got the root (parent tag) of our xml file using getroot().
The xml. etree. ElementTree module implements a simple and efficient API for parsing and creating XML data. Changed in version 3.3: This module will use a fast implementation whenever available.
The getchildren method returns a list of sub-elements of an Element object. You could then use the built-in index method of a list.
>>> import xml.etree.ElementTree as ET
>>> root = ET.Element("html")
>>> head = ET.SubElement(root, "head")
>>> body = ET.SubElement(root, "body")
>>> root.getchildren().index(body)
