Asp Forum - XML-XSD Processing/Creation.

Hi All,

So i'm working with the WITSML standard, which is a pretty
massive standard defined in XML for the transfer of oilfield data.
There are a ton of XSD files for defining and checking all data in the
WITSML format. I'd like to be able to easily create XML based on the
types defined by the WITSML XSD files. Is there any way to create a
basic XML object based on an XSD file and then populate it with data.
Can i create python classes based off the XSD files? What else can I
do with the XSD files? I'm looking for a really simplistic way to work
with WITSML in python.

Regards,
Kenneth Miller

Thanks a ton!

I cannot answer (yet) the question of generating XML data from an XSD. But for
writing out XML files I like to use either ElementTree or lxml. Very easy and
straightforward use of XML from Python in my opinion.

If it's really such a complex XML language, the tool above might or might not
be of any help, as it doesn't support the whole XSD standard (and XML Schema
is very complex). It's worth a try, but don't expect too much.

The lxml way of dealing with XML languages is namespace implementation:

However, there isn't currently a way to automatically bootstrap an
implementation, especially not in XSD, so it depends on the language how much
work it will be to get this to a usable state.

Just a bump in an attempt to get some more help.
