如何附加递归 API 调用并将结果写入 CSV？

Question

我必须根据 XML API 响应创建 csv。我有两个问题。一 - 由于某种原因，我进行的 API 调用在添加后没有保存到列表中，列表完全消失了。

two - 因为我无法存储 API 调用的结果，所以我不知道如何抓取结果并创建 csv。

代码设置为首先获取组级别数据，然后获取每个 ID 并应用到 people.profile API 调用以获取他们的个人资料信息。我可以做这部分，这是代码：

def xml_event_info(eventID):       
    xml ='''        
    <?xml version="1.0" encoding="UTF-8"?>
    <YourMembership>
       <Version>2.25</Version>
       <ApiKey>xxxx</ApiKey>
       <CallID>001</CallID>
       <></>
       <SaPasscode>xxxx</SaPasscode>
       <Call Method = "Sa.People.Profile.Get">
           <ID>{}</ID>
       </Call>
    </YourMembership>        
    '''        
    headers = {'Content-Type': 'application/x-www-form-urlencoded'}
    r = requests.post('https://api.yourmembership.com', 
                      data=xml.format(eventID), headers=headers)        
    print(r.text)      


xml ='''    
<?xml version="1.0" encoding="utf-8" ?>
<YourMembership>
    <Version>2.25</Version>
    <ApiKey>xxxx</ApiKey>
    <CallID>001</CallID>
    <SaPasscode>xxxx</SaPasscode>
    <Call Method="Sa.Groups.Group.GetMembershipLog">
        <GroupID>12345</GroupID>
        <ItemID></ItemID>
        <StartDate></StartDate>
    </Call>
</YourMembership>
'''        
headers = {'Content-Type': 'application/x-www-form-urlencoded'}
r = requests.post('https://api.yourmembership.com', data=xml, headers=headers)
print r.text
# BUILD XML TREE OBJECT    
tree = et.fromstring(r.text)

storage = []
# PARSE People ID TEXT AND PASS INTO FUNCTION
for i in tree.iterfind('.//ID'):
     y = xml_event_info(i.text)
     storage.append(y)

在评论“解析人员 ID 文本并传递给函数时，当我迭代 API 调用时，值没有保存到列表 'storage' 中，因此，一旦通话结束 'storage' 消失了，当我去打印列表 'storage' 时它说 'None'。

其次，y = xml_event_info(i.text) 是我需要解析为 CSV 的实际人员资料数据，这就是 XML 的样子：

<?xml version="1.0" encoding="utf-8" ?>

有没有办法让每个 xml 标签快速成为 csv 中的一列？如果我也有的话，我不介意手动输入要写入的字段。但想将结果保存并拆分为 csv。 CSV 应如下所示：

ID     FirstName   LastName EmailAddr
12312   John        Smith    john@smith.com

提前谢谢你。

此代码获取输入 xml 文件中每个配置文件中 'children' 的标签和文本。但是小心，此代码不会尝试编译出现在所有配置文件中的所有标签的完整集合。如果某些个人资料具有其他人没有的标签，那么这将导致编写 csv 文件时变得复杂，因为在开始编写之前您需要知道 csv 中有多少列。
