pyexpat does not support Python encoding names

[slozier]

pyexpat does not support Python encoding names. This is because the names are not understood by System.Xml.XmlReader which is used under the hood.

from xml.etree import ElementTree as ET
text = ET.fromstring(b"<?xml version='1.0' encoding='iso8859'?><a></a>")

A possible solution for this would be to peek at the start of the XML file to get the encoding, do the decoding ourselves and then use a StringReader. Another option would be to peek at the start, and replace the encoding with an alias that XmlReader understands.

I think your example needs to use ET.fromstring
