ElementTree element index look up

Question

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 subelement?

Answer 1

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)

Answer 2

import xml.etree.ElementTree as ET
root=ET.Element('C:\Users\Administrator\Desktop\ValidationToolKit_15.9\ValidationToolKit_15.9\NE3S_VTK\webservice\history\ofas.2017-1-3.10-55-21-608.xml')
childnew=ET.SubElement(root,"354")
root.getchildren().index(childnew)
0
list(root).index(childnew)
0
