(I think you mean "python XML parsing libraries"; it's the library,
not the API, that preserves comments or not.)

I don't have an answer, but this may help to get more information.
The XML 1.0 specification allows for, but does not require, retention
of comments for access by the application:

2.5 Comments

[Definition: .... an XML processor MAY, but need not, make it
possible for an application to retrieve the text of comments. ...]
