the approach that the OP is apparently trying to follow is
clearly misguided.
I completely agree. However, I recommend that we let him find out on his
own. I suspect he has some idiomatic usage of XML, perhaps with all
namespace prefixes defined in the root

Well, it solves the problem

Given that XML documents can be very large I'd rather avoid a parsing of
the document [beyond what lxml/etree] has already done] just to retrieve
the namespaces and their prefixes.
In order to find out which prefixes are used in the document and which set

BTW, I'm still not sure I understand your problem. Could you provide
some more details?
Wouldn't it be easier if you told the OP how to access the prefix
mappings in lxml etree, or, if this was actually not possible, admitted
that it is actually not possible?

How so? Why do you say it's a "method", and why do you say "of"?
Usually, xpath expressions are *not* part of the document they ope
