current output with no filenames and jumbled differences


Python
{'QWZ5671': [{'color_swatch': ['Red', 'pink']}],
 'RRX986': [{'item_number': ['RRX986', 'peac']},
            {'color_swatch': ['hey', 'pet', 'Burundy', 'Nay', 'lost', 'Red']}]}


Expected output with proper formatting and filenames. if someone can help with this

Python
{'QWZ5671': [{'color_swatch': ['test1.xml': 'Red', 'test2.xml': 'pink']}],
 'RRX986': [{'item_number': ['test1.xml': 'RRX986', 'test2.xml': 'peac']},
            {'color_swatch': ['test1.xml':'Burundy, 'test2.xml':'hey'], 
                             ['test1.xml':'Nay', 'test2.xml':'pet'],
                             ['test1.xml': 'Red','test2.xml': 'lost']}]}


What I have tried:

Python
from lxml import etree
from collections import defaultdict
import pprintpp
from pprintpp import ppprint as pp

root_1 = etree.parse('test1.xml').getroot()
root_2 = etree.parse('test2.xml').getroot()

d1, d2 = [], []
for node in root_1.findall('.//catalog_item'):
    item = defaultdict(list)
    for x in node.iter():
        if x.attrib:
            item[x.attrib.keys()[0]].append(x.attrib.values()[0])
        if x.text.strip():
            item[x.tag].append(x.text.strip())
    d1.append(dict(item))

for node in root_2.findall('.//catalog_item'):
    item = defaultdict(list)
    for x in node.iter():
        if x.attrib:
            item[x.attrib.keys()[0]].append(x.attrib.values()[0])
        if x.text.strip():
            item[x.tag].append(x.text.strip())
    d2.append(dict(item))

d1 = sorted(d1, key = lambda x: x['item_number'])
d2 = sorted(d2, key = lambda x: x['item_number'])

res_dict = defaultdict(list)
for x, y in zip(d1, d2):
    for key1, key2 in zip(x.keys(), y.keys()):
        if key1 == key2 and sorted(x[key1]) != sorted(y[key2]):
            res_dict[x['item_number'][0]].append({key1: list(set(x[key1]) ^ set(y[key2]))})

if res_dict == {}:
  print('Data is same in both XML files')
else:
  pp(dict(res_dict))

You need to add the source file names to each item in the lists.

It is done. Any suggestion for jumble sorting in the current output? like it is coming in

{'color_swatch': ['hey', 'pet', 'Burundy', 'Nay', 'lost', 'Red']}]}

values are mixed from both xmls
