本文介绍了如何使用Python ElementTree获取元素树的所有子元素?的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
我想找到一种方法来获取元素树的所有子元素,就像 ElementTree.getchildren()
那样,因为 getchildren()
自python 2.7版本以来已被弃用,尽管现在仍可以使用,但我现在不想使用它。
I want to find a way to get all the sub-elements of an element tree like the way ElementTree.getchildren()
does, since getchildren()
is deprecated since Python version 2.7, I don't want to use it anymore, though I can still use it currently.
谢谢。
推荐答案
elem
的所有子元素(后代):
All sub-elements (descendants) of elem
:
all_descendants = list(elem.iter())
一个更完整的示例:
>>> import xml.etree.ElementTree as ET
>>> a = ET.Element('a')
>>> b = ET.SubElement(a, 'b')
>>> c = ET.SubElement(a, 'c')
>>> d = ET.SubElement(a, 'd')
>>> e = ET.SubElement(b, 'e')
>>> f = ET.SubElement(d, 'f')
>>> g = ET.SubElement(d, 'g')
>>> [elem.tag for elem in a.iter()]
['a', 'b', 'e', 'c', 'd', 'f', 'g']
要排除根本身:
>>> [elem.tag for elem in a.iter() if elem is not a]
['b', 'e', 'c', 'd', 'f', 'g']
