Rename Files based on XML file

[klturi421]

I am working to rename a list of files that are received daily with an index key which is an XML file. Currently file names are given in an indistinct manner. The existing file name structure is as follows AT1_ID1_TT3_ID6-1624820795.4719.WAV .

I receive thousands of tiles with the same name which is a pain to try and identify which file I am looking for. Ideally, the file name would be renamed something a little more meaningful like `Smith John - 6-10-2021 5555555555.WAV'

The first set of code is the XML structure. I am looking to join the

for file_name in os.listdir('./06-27-2021'):
    if file_name.endswith(".WAV"):
        for child in root:

I get the following error:

From what I gather the code is searching for 'Gloria Reyes_2021-06-27 15_07_7878206203.WAV' but not finding it, instead, I need it to look for 'AT1_ID1_TT3_ID6-1624820795.4719.WAV' and rename it. I'm sure that I have something swapped but I can't quite figure out what it swapped.
