在xml文件中使用python替换多个单词

Question

我需要替换远程XML文件中的一些单词。

我设法改变了HD＆＃39; HD＆＃39;使用第一行，但其余的行似乎被跳过了＆＃39; if语句＆＃39;。

for item in items:
    try:
        name = item('title')[0].string
        name = name.replace('HD', 'HDD')
        name = name.replace('aa help', 'aa hel')
        name = name.replace('zs a help', 'zs a help g')
        if name is None:
            name = 'unknown?'
    except:
        addon_log('Name Error')
        name = ''

我哪里错了？
