you'll need to pass the locals() or globals() manually. Can't be done
(cleanly) otherwise. Check the following code:

import re

x1=1
x2=20
x3=30
q6=40

def make_dict(regex, nsmapping):
    output_dict = {}
    compiled_regex = re.compile(regex)
    for key, value in nsmapping.items():
        if compiled_regex.match(key):
            output_dict[key] = value

    return output_dict




d = make_dict("x[123]", locals())

print d
