Question

我从xml文件中解析了节点值，并想将输出另存为python中的csv，但是在编写csv时出错。

下面是xml的摘要，其中包含我要解析的唱名投票结果的信息，由于我只想从中获取FirstName / LastName / PartyName / VoteValueName / AffiliationId，因此我构建了以下代码

from xml.dom import minidom 
doc = minidom.parse("C:/../vote880.xml")

filename = "vote880.csv"
f = open(filename, "w")
headers = "FirstName, LastName, PartyName, VoteValueName, MemberId, AffiliationId\n"
f.write(headers)

VoteParticipants = doc.getElementsByTagName("VoteParticipant")
for VoteParticipant in VoteParticipants:
    FirstName = VoteParticipant.getElementsByTagName("FirstName")[0]
    LastName = VoteParticipant.getElementsByTagName("LastName")[0] 
    PartyName = VoteParticipant.getElementsByTagName("PartyName")[0] 
    VoteValueName = VoteParticipant.getElementsByTagName("VoteValueName")[0]  
    MemberId = VoteParticipant.getElementsByTagName("MemberId")[0]  
    AffiliationId = VoteParticipant.getElementsByTagName("AffiliationId")[0]

    print("FirstName:%s, LastName:%s, PartyName:%s, VoteValueName:%s, MemberId:%s, AffiliationId:%s" %
          (FirstName.firstChild.data, LastName.firstChild.data, PartyName.firstChild.data, VoteValueName.firstChild.data, MemberId.firstChild.data, AffiliationId.firstChild.data))

f.write(FirstName + "," + LastName + "," + PartyName + "," + VoteValueName + "," + MemberId + "," + AffiliationId + "\n")
f.close()

但是，python返回TypeError: unsupported operand type(s) for +: 'Element' and 'str'。

如果我正确理解，看来我需要在编写csv之前将从xml获得的元素转换为字符串，但是我不知道该怎么做。任何评论将不胜感激。
