copying an element will "reset" is nsmap

Hi, I have another unexpected behaviour.

I have a root element with many namespaces declared. When I introspect
the first child of the root, the nsmap is full. When I "deepcopy" it,
only the the namespace used in the tag name is kept. If the name is not
qualified, nsmap turns empty. (Sorry if I don't use the right XML semantic.)

I tried to reaffect nsmap but the attribute is read-only.

How could I preserve the nsmap attribute of unattached elements?

Regards,

Hervé

Shouldn't this message be on Python-specific list ? Or at *least* marked as 
"OFF-TOPIC" ?

That said, you can choose between the official download on the Python page:

http://www.python.org/download/

... or ActivePython's distribution:

I would guess from the context of this mailing list that the OP meant
binary builds of lxml for that platform.

I think that would be a question for Sidnei.

My guess is that the namespaces end up being declared either on the new
document (libxml2) node, or at the element where they are first used in the
copied tree.

If the latter, there's not that much that lxml can do about it (I guess).
If the first, we might be able to fake something by adding the document
wide namespace declarations to the .nsmap of the root element. That might
be a nice feature anyway.

Could you check if the namespaces end up in .nsmap dicts at deeper tree
levels or not? (a short example script would be helpful, BTW)

Not that I know of.

Could you post the command line options of the calls to gcc that distutils
print during the build?

To be honest, I have no idea. But that's definitely a
distutils/setuptools/easyinstall thing, not an lxml problem.

Uhm. Yeah. I thought I had those but I have only 3.0. When is the next
release of lxml due? If it will take a while I can upload a 3.1 build
of lxml 2.2.2.

Re: Python 3.1 binary on Windows?

I believe he's looking for pre-build lxml binaries that target Python 3.1 on Windows.

I'd like to get a 2.2.3 ready soon and a 2.3 at about the same time, but
there's no deadline.

Please do, that will certainly help some users. The main problem on 3.x is
still the lack of available external (binary) packages.
