It's not unsurprising, especially with bad XML structures.

Generally, I work with XML only as a transport layer; and most of the
time, it's for a document structure that would be better served by
JSON anyway. (This may mean that I have an unfairly negative view of
XML, but it's extremely common.) My usual technique is to parse it
into something native (usually a dictionary - and probably the same
structure that the other end constructed the XML from), then work with
that. For example, querying the ePond API [1] gives back a pile of XML
data, so I might have a single function that performs a synchronous
HTTP query, takes the response body, parses it using a fairly generic
XML parser like lxml, then digs three levels into the resulting tree
to pull out the bit that actually matters, leaving behind all the
framing and stuff.

The less time you spend with actual XML, the better. XML is not the answer.
