Take a look at
    http://home.eol.ca/~parkw/park-january.html
on "Expat XML" section towards the end.  Translating it to Python is
left for homework.

In essence, 
    indent=..
    start () {
	local "${@:2}"
	echo "${indent|*XML_ELEMENT_DEPTH-1}$label"
    }
    xml -s start "`< file.xml`"
which prints
    ..ABC
    ....EFGA
    ......ABDG
    ....MON
    ..A1
    ....FGA
    ......BG
with modified input, ie. wrapping XML pieces into single root tree.
