Syntax issues when parsing pubmed baseline xml

[robinweisenburger]

Hi there,

I was trying to parse the pubmed baseline xml from https://ftp.ncbi.nlm.nih.gov/pubmed/baseline/ with the pp.parse_medline_xml function. But every second file I get an syntax error:

File "/home/xxx/.local/lib/python3.12/site-packages/pubmed_parser/medline_parser.py", line 751, in parse_medline_xml
    for event, element in etree.iterparse(f, events=("end",)):
                          ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

lxml.etree.XMLSyntaxError: Opening and ending tag mismatch: ArticleTitle line 1538866 and ArticleId, line 1538867, column 39

If I try to parse the same file with xmltodict it works.
