合并多个XML文件

Question

我一直在使用此脚本（ 从命令行合并多个XML文件 ）来在Debian Jessie上合并xml文件。 我正在迁移到运行CENTOS 6.6 x86_64的专用服务器。 我在使脚本在新环境中运行时遇到问题。 任何帮助，将不胜感激。

python版本2.7

剧本

#!/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:])

Answer 1

此错误可能是由于使用python2.6引起的，因为extend仅出现在python 2.7中。 您确定使用python 2.7吗？ 你能跑吗

python --version

？

可能是系统中python的默认版本是2.6，而您需要指定正确的版本而不是

#!/usr/bin/env python
