Understanding the arguments for SubElement factory in ElementTree

[B Mahoney]

Your SubElement call is lacking the attrib argument, but you can't set
text, anyway.

The elementtree source makes it clear, you can only set element attrib
attributes
with SubElement

def SubElement(parent, tag, attrib={}, **extra):
    attrib = attrib.copy()
    attrib.update(extra)
    element = parent.makeelement(tag, attrib)
    parent.append(element)
    return element
