for event, element in etree.iterparse(path_to_file, tag="BlogPost"): for child in element: print child.tag, child.text element.clear()
最后的清除将阻止您使用过多的内存。
[更新：]要获得“…之间的所有信息，作为字符串”，我想您需要以下其中一项：
for event, element in etree.iterparse(path_to_file, tag="BlogPost"): print etree.tostring(element) element.clear()
要么
for event, element in etree.iterparse(path_to_file, tag="BlogPost"): print ''.join([etree.tostring(child) for child in element]) element.clear()
甚至：
for event, element in etree.iterparse(path_to_file, tag="BlogPost"): print ''.join([child.text for child in element]) element.clear()
