没有得到xml文件输出

Question

我想使用下面提供的python代码来读取xml文件email.xml（下面的数据），我不能够打印XML文件中存在的实际数据，但获得下面的输出。我哪里错了？

电流输出：

xmlfile 
<open file 'email.xml', mode 'r' at 0x0226AF98> 
[<DOM Element: to at 0x231d620>] 
[<DOM Element: cc at 0x231d6c0>] 
[<DOM Element: bcc at 0x231d760>] 

Python代码：

import xml.dom.minidom as minidom 

def getemaildata(): 
    # Open the XML file 
    xmlfile = open('email.xml','r') 
    print "xmlfile" 
    print xmlfile 
    dom = minidom.parse(xmlfile) 
    email=dom.getElementsByTagName('email') 
    for node in email: 
     toemail=dom.getElementsByTagName('to') 
     print toemail 
     ccemail=dom.getElementsByTagName('cc') 
     print ccemail 
     bccemail=dom.getElementsByTagName('bcc') 
     print bccemail 
return (toemail,ccemail,bccemail) 

def main(): 
(To,CC,BCC)=getemaildata() 

if __name__ == '__main__': 
main() 

email.xml文件：

<email> 
    <to>[email protected];[email protected]; 
     [email protected];[email protected];</to> 
    <cc> data.team </cc> 
    <bcc>[email protected]</bcc>  
</email> 

Answer 1

您正在从XML解析器获取“元素”对象的列表。您需要进一步迭代才能找到实际的“文本”节点。

例如：

# this returns a list of all Elements that have the tag "to" 
toemail=dom.getElementsByTagName('to') 

# Here we take the first node returned with tag 'to', then it's first child node 
textnode = toemail[0].childNodes[0] 

# print the data in the textnode 
print textnode.data 

要清洁从文本节点中的地址：

for address in textnode.data.split(';'): 
    if address == '': 
     # Catch empty entries as a result of trailing ; 
     continue 
    email = i.strip().strip('\n') 
    print email
