Question

任何人都可以帮助我获取用于比较两个XMLS的Python代码并输出日志文件中的差异。我是python的新手我已经在anaconda python 3.5.2中尝试了这个链接（Comparing two xml files in python）中的代码，但它引发了异常。我在anaconda中尝试过以下代码，但它会引发语法错误 def init （自我）：

import xml.etree.ElementTree as ET

class XmlTree():

    def __init__(self):
        self.hdlr = logging.FileHandler('xml-comparison.log')

Anaconda代码用于比较两个xml并输出差异
