Python ElementTree中不区分大小写的findall [英] Case Insensitive findall in Python ElementTree

问题描述

我必须解析具有在任何情况下都可能存在的标记名称(混合、上、下等)的 XML，但我事先不知道会是什么情况.如何让 findall 在 ElementTree 中完全不区分大小写?

I have to parse XML that has tag names that may be in any case (mixed, upper, lower, etc) and I don't know what the case will be beforehand. How can I make findall be totally case insensitive in ElementTree?

   # Does not work
   variables = message.findall("VaRiAbLE")

推荐答案

您只需从树中获取字符串，将其小写，然后重新制作树.那么它应该是可解析的

You simply get the string from the tree, lowercase it, and remake the tree. Then it should be parseable

import xml.etree.ElementTree as ET
def to_parseable(tree):
    t = ET.tostring(tree)
    t = t.lower()
    return ET.fromstring(t)
