参考：The Hitchhiker's Guide to Python: XML parsing
<mydocument has="an attribute">
<and>
<many>elements</many>
<many>more elements</many>
</and>
<plus a="complex">
element as well
</plus>
</mydocument>
xmltodict
安装：pip install xmltodict --user
import xmltodict
with open('path/to/file.xml') as fd:
doc = xmltodict.parse(fd.read())
doc['mydocument']['@has'] # == u'an attribute'
doc['mydocument']['and']['many'] # == [u'elements', u'more elements']
doc['mydocument']['plus']['@a'] # == u'complex'
doc['mydocument']['plus']['#text'] # == u'element as well'
