ElementTree element index look up

Question

Just a beginner question. I'm using "xml.etree.ElementTree" module to create an XML document with Python 3.1 from another structured document.

However, I cannot seem to locate an ElementTree function that returns the index of an existing subelement. I'm sure it's in there somewhere.

Any help would be much appreciated.

Thanks,

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)
