from xml.dom import minidom

dom = minidom.parseString('<eg>example text</eg>')

for event, elem in etree.iterparse(StringIO(xml)):
    print elem.text

AFAIK Google App Engine provides a fairly complete Python environment for you to use. Since Python comes with "batteries included" you may want to evaluate the different APIs which vanilla Python offers you: http://docs.python.org/library/markup.html

AFAIK Google App Engine提供了一个相当完整的Python环境供您使用。由于Python附带“包含电池”，您可能需要评估vanilla Python为您提供的不同API：http：//docs.python.org/library/markup.html
