[Record it] Error reporting AttributeError: 'NoneType' object has no attribute 'text'

question

The following error occurs when running the xml to txt file

The reason is that some of the different xml files may still exist <difficult>0</difficult>, and some files do not. This problem cannot be solved in the original code.
The original code is as follows:

Solution

Change it to the following

 #difficult = obj.find('difficult').text
        if obj.find('difficult'):
            difficult = int(obj.find('difficult'.text))
        else:
            difficult = 0

Subsequent runs succeed.
