[XML-SIG] XML from scratch and transformation with XSLT

[Marc Garcia]

I want to make a simple program in python that get data from a database 
(or other source), create a new xml document with it and then parse it 
with an existing xslt sheet.

I'm testing many libraries, such as libxml2/libxslt, lxml, 4suite, and 
in different ways, dom and sax methods...

Do somebody know what is the simplest way to achieve it? I'm having some 
problems with all of it (encoding problems, installation bugs, more than 
one library required...) and I need some expert tips to know what way I 
have to work on.

Thanks in advance,
  Marc
