My Generator yields a dictionary. Return entire file not specified key, value

[Sayth Renshaw]

When I am running my file which takes a file off the command line reads it and creates an objecitifed xml instance and then parses for each attribute into a dictionary and then yields it.

At this point I am tring to use it to obtain specific key value elements, however I keep being returned the whole file output rather than the selection key.really not sure where I am going wrong.

The key part of my file that is using the generator is

for item in parseXML():
    number = item["number"]
    print(number)

Rest of file for reference

from lxml import objectify
import argparse
import os

parser = argparse.ArgumentParser()
parser.add_argument("path", type=str, nargs="+")
parser.add_argument('-e',
                    '--extension',
                    default='',
                    help='File extension to filter by.')

args = parser.parse_args()
name_pattern = "*" + args.extension
my_dir = args.path[0]

for dir_path, subdir_list, file_list in os.walk(my_dir):
    for name_pattern in file_list:
        full_path = os.path.join(dir_path, name_pattern)


def getsMeet(file_list):
    """generator which yields sorted file."""
    for filename in sorted(file_list):
        filename = my_dir + filename
        yield filename


def parseXML():
    """

    for file in getsMeet(file_list):
        with open(file, "rb") as f:
            xml = f.read()

            root = objectify.parse(xml)
            atts = ("number", "id", "horse", "saddlecloth", "barrier",

            for sample in root.xpath('//race/nomination'):
                noms = (dict(zip(atts, map(sample.attrib.get, atts))))
                yield noms


for item in parseXML():
    number = item["number"]
    print(number)
