read/write XML

[Torsten Mohr]

Hi,

i just took a look into the python documentation regarding XML.
XMLDOM look quite big, so i took another look at "minidom".

So is minidom the preferred way to go to read an XML, handle
its data and also write XML?

In the example (13.7.2, SLideshow) the structure seems to be
read into a "dom", but to check its structure against some
criteria seems to be completely missing, e.g.:

- only defined elements used
- at least one slide in the slideshow
- others ...

How can i check a "dom" against these criteria?


Best regards,
Torsten.

Depends on many other things.

You can use DTD, RELAX NG or Schematron. For DTD use PyXML or
libxml2. For RELAX NG, use 4Suite, XVIF stand-alone or libxml2. For
Schematron use Scimitar or an XSLT Schematron implementation.

We can offer more detailed answers if you ask more detailed questions.
