process_tuv(tuv) causes IndexError

[Aariciah]

Hi, I just tried to read a file using

from tmx2dataframe import tmx2dataframe
metadata, df = tmx2dataframe.read("de-en.tmx")

and it gave me the following error:

---------------------------------------------------------------------------
IndexError                                Traceback (most recent call last)
Cell In [2], line 2
      1 from tmx2dataframe import tmx2dataframe
----> 2 metadata, df = tmx2dataframe.read("de-en.tmx")

     44     count_unpaired = count_unpaired + 1
     45 else:

     47     targetlang, targetsentence = process_tuv(tu.getElementsByTagName('tuv')[1])
     48     item = {

     53     }

      9 seg = tuv.getElementsByTagName('seg')[0]

     11 return lang, txt

IndexError: list index out of range

This repo seems a little dead but it would be great if someone knew what is going on! Thanks
