enumerate XML tags (keys that will become headers) along with text (values) and write to CSV in one row (as opposed to "stacked" values with one header)

XML is not unordered. The document order is well defined and entirely
obvious from the data. Whether this order is relevant and has a meaning or
not is, however, not part of XML itself but is left to the semantics of the
specific document format at hand. Meaning, XML document formats can choose
to ignore that order and define it as irrelevant. That doesn't mean it's
not there for a given document, but it may mean that a re-transmission of
the same document would be allowed to use a different order without
changing the information.

This property applies to pretty much all structured data formats and not
just XML, by the way, also to CSV and other tabular formats.
