合併多個XML文件

Question

我一直在使用此腳本（Merge multiple XML files from command line）在Debian Jessie上合併xml文件。我正在轉向運行CENTOS 6.6 x86_64的專用服務器。我有問題讓腳本在新環境中工作。任何幫助，將不勝感激。

蟒版本2.7

腳本

#!/usr/bin/env python 
import sys 
from xml.etree import ElementTree 

def run(files): 
    first = None 
    for filename in files: 
     data = ElementTree.parse(filename).getroot() 
     if first is None: 
      first = data 
     else: 
      first.extend(data) 
    if first is not None: 
     print ElementTree.tostring(first) 

if __name__ == "__main__": 
    run(sys.argv[1:])

此錯誤可以通過使用python2.6的原因引起的，因爲僅延伸在python 2.7出現。你確定你使用Python 2.7嗎？請問你能跑

python --version 

？

它可以在你的系統中的蟒蛇默認版本是2.6，你需要指定正確的，而不是

#!/usr/bin/env python
