合并多个XML文件

Question

我一直在使用此脚本（Merge multiple XML files from command line）在Debian Jessie上合并xml文件。我正在转向运行CENTOS 6.6 x86_64的专用服务器。我有问题让脚本在新环境中工作。任何帮助，将不胜感激。

蟒版本2.7

脚本

#!/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:])

此错误可以通过使用python2.6的原因引起的，因为仅延伸在python 2.7出现。你确定你使用Python 2.7吗？请问你能跑

python --version 

？

它可以在你的系统中的蟒蛇默认版本是2.6，你需要指定正确的，而不是

#!/usr/bin/env python
