I'd use iterparse() for the parsing, that allows you to construct the .dbf
content on the fly.

http://codespeak.net/lxml/parsing.html#iterparse-and-iterwalk

Working with the data elements returned by the iterparse iterator is quite
easy, you'll be fine with using the properties .tag and .text, as well as
the .find() method to find subelements.

http://codespeak.net/lxml/tutorial.html#the-element-class

If you can afford to load the entire XML tree into memory, you can also
try lxml.objectify, which will give you a Python-like interface to the
data.

http://codespeak.net/lxml/objectify.html

Note that the lxml.objectify in-memory tree is most likely a lot more
memory friendly (and the parsing is definitely faster) than what the
recipe gives you.

I do not know any step-by-step guide that describes how to convert an XML
format to .dbf. I guess you'll have to figure out the mapping code
yourself to a certain extent. I gave you quite a number of references
including some tutorials and a link to a library that handles the dbf
format. If you want someone else to write the program for you for free,
you should say so.

If by "put in place" you mean "install", how about the installation guide
provided by lxml's web site:

http://codespeak.net/lxml/installation.html

Any further help would require some more information from your side, such
as the operating system you use, which Python version, etc.

BTW, the comp.lang.python newsgroup has a lot more readers than the
xml-sig list and therefore often provides better help for newbees. This
might make an interesting read:

That's a problem with your gcc installation. It doesn't support the -m64
option. You need to invoke the 64-bit compiler, or build for a 32-bit
Python.

Hi,
I've a problem with lxml in an .exe file from py2exe. This is the
error message:

Traceback (most recent call last):

I've tryed to build a minimal file but it doen't cause this problem.
but there is no error-message. It simply closes the console.

I've found a similar problem in the archives of lxml-dev but I don't
understand the solution.

Hi,

the best place to ask this would have been comp.lang.python or the
(presumably existing) py2exe mailing list.

I never used py2exe, but reading the post you referenced, I'd say the
problem is that _elementpath is imported from C code, so py2exe can't see
that it's used. Passing

    packages : ['lxml']

to py2exe should solve this. It will stuff more modules into the
executable than required, but it will also make sure nothing that *is*
required will get lost.

According to the website (http://effbot.org/zone/element-index.htm)
1.3 has been in alpha for a year and a half.  I like that elementtree

Well, elementtree is a single-person project. So you better ask
Fredrik Lundh - nobody else will be able to provide you with
a meaningful answer.

Sure, but it's also part of the python standard library, and this is
the XML-SIG list.   The chance is high someone here will know, and
then google will know the answer, too.

One of the problems we've had in the XML-SIG arena is people don't
know which libraries to use.  PyXML is still referred to as the
standard in many places, even though it's no longer in development.
lxml is still in development, but it's not in the standard library,
and uses elementtree's style as a base.  It's confusing, and the more
information we have describing the current situation, the better off
we'll be.

Anyway, that's why I asked here, rather than going straight to Lundh.

Note that ElementTree 1.2.x is a very mature piece of software. If there's
no new release for years, that doesn't mean it's abandoned.

ET 1.3 is intended to fix API problems that older ET versions have
aggregated, very much in the way Py3 is intended to clean up the Python
language. So it's not meant as a bug fix, it's meant as a new thing that
breaks code. I think the main problem it currently has is that it fixes so
few things that it'd be hard to convince people to change their code to
support it. I expect that (plus the usual lack of time) to be the main
reason why Fredrik didn't finish it up yet. If he had more feedback about
it by users, he'd probably get around to pull another release. But as long
as there's no clear interest in following that path, I wouldn't expect 1.3
final any time soon.

That's exactly what I needed to know.  So as I'm looking at XML
libraries to use, ElementTree is a good place to start, since it'll be
around.  And if I need something a little more, lxml may be a good
migration path since it's similar, but has dependencies.

Thanks for the help.
