Merge multiple XML files

Question

I've been using this script (Merge multiple XML files from command line) to combine xml files on Debian Jessie. I'm in the process of moving to a dedicated server running CENTOS 6.6 x86_64. I'm having issues getting the script to work in the new environment. Any Help would be appreciated.

python version 2.7

THE SCRIPT

#!/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:])

THE ERRORS

This error can be caused by using of python2.6, because extend appears only in python 2.7. Are you sure that you use python 2.7? Can you, please, run

python --version

?

It can be that the default version of python in your system is 2.6 and you need to specify the right one instead of

#!/usr/bin/env python

Thanks, I got it figured out. I had the xmlcombine.py set to call python2.7 but not the main script. shopt -s extglob for f in $PATH_VAR/*; do [ -d $f ] && cd "$f" && python27 $SCRIPT/xmlcombine.py !(combined).xml > "$f"-combined.xml; done; – Pop Sep 03 '15 at 16:26
