無法在python中替換xml中的值

我一直試圖弄清楚這幾個小時，但我似乎無法找到解決方案。我有以下xml格式：無法在python中替換xml中的值

我想要做的就是在「Cusip」字段中添加一些值。有人可以幫忙嗎？

我一直在使用下列內容：

import xml.etree.ElementTree as ET 
tree = ET.parse('//lo-dfs/users/username/Desktop/test.xml') 
root = tree.getroot() 

data = root.getchildren()[1] 
print data 

for child in data: 

    child.attrib['Cusip']= "Test"

是否有人可以幫助我在做什麼錯在這裏？

謝謝

你是否有錯誤？你有沒有把樹寫回磁盤（我假設你想存儲更改？） – mgilson

我沒有得到任何錯誤，是的，我確實想存儲更改。你能推薦一種如何做到這一點的方法嗎？ @mgilson – Nant

你的xml貼出來似乎不正確 –

找到利用一切CashDividend元素，例如findall()，設置屬性值，你已經這樣做，並通過tree.write()轉儲修改樹到XML文件：

import xml.etree.ElementTree as ET 

tree = ET.parse('test.xml') 
root = tree.getroot() 

for cash_dividend in root.findall("CashDividend"): 
    cash_dividend.attrib['Cusip']= "Test" 

tree.write('test.xml')

Works的我。
