Python snippet for getting file name under xml folder

import os
pathx = (os.path.dirname(__file__)+str('\\xml\\'))
list1 = os.listdir(pathx)

paths = (''.join(map(str,list1)))
#GET Files inside Folder
#print(paths)
#Insert in xml parse

It is more reliable to join paths using os.path.join , it will take care of escaping the characters and pick the path separator for your system. Try to use the following line:

pathx = (os.path.join(os.path.dirname(__file__), 'xml'))
