[lxml-dev] Converting an objectified lxml tree to a standard etree one.

[John Krukoff]

Is the best way to convert an objectified (with lxml.objectify) element
tree to a standard etree based one just to serialize and reparse? Is the
reverse transform just as hard?

As a use case, I've been experimenting with lxml.objectify, and quite
liking it. However, I've a large library of support functions that I
want to use that expect plain etree elements, and I'm trying to find an
efficient way to convert between the two. I care more about memory than
CPU time.

Additionally, there's something odd about the objectify module that
prevents help from working:

>>> help( objectify )
