Re: XML from scratch and transformation with XSLT

Why would you do this?  That is, you are pulling data from a database  
into Python, then transforming it into XML, then running that XML  
through an XSLT transformation.  Why not pull the data into Python,  
manipulate them in Python, then output as the end-result XML?  That  
is, transcribe from Python directly to the desired final XML format?

I can think of a couple of reasons to do it your way -- the XSLT  
engine might well be faster than the Python transformation, it might  
be easier to output simple XML and then expand it via XSLT, etc. --  
but I'm wondering if you've considered the above simpler path?  It  
might make your life easier.

Re: XML from scratch and transformation with XSLT

Thanks for your opinion Peter, it have been useful to me.

I'm used to do transformations directly when I get data from database, 
but I think that this new way make applications easier to maintain, the 
code is logically divided, and the this is more clear.

The ElementTree is good, and for me the best would be use the lxml 
implementation so it have xslt support, but it isn't a rpm package and 
is difficult for me install it in my fedora server without development 
environment.

Finally I did it with libxml2/libxslt, after solving some encoding 
problems. Probably I'll develop my own class, to abstract it, and to 
make it easy if in the future I want to change this library.

Thanks,
  Marc

PyXML install problems on Mac OS X

I hope this is the right place to ask about this...

I have Mac OS X, 10.4.6 (updated this morning) with the new Python  
2.4.3 Universal Binary just released at python.org.

I'm trying to install PyXML, but having problems. It appears that,  
for some reason, gcc is not looking in /usr/include for header files.  
I've tried looking through setup.py to see what was going on, but I'm  
a Python newbie and just got lost in the code.

For reference, /usr/include/limits.h does exist, and which gcc  
produces /usr/bin/gcc which is a link to /usr/bin/gcc-4.0 which seems  
to be the binary.

Any ideas? Output of python setup.py build is given below.

Thanks,
Todd

Question about licenses of various pieces of PyXML

All,

I have a question about the licenses associated with various bits and
pieces of PyXML.

In particular, I would like to know which files in the PyXML package are
associated with the various subpackages of PyXML (for instance, most of
the stuff in xpath is associated with the 4DOM subpackage).  From that, I
figure out the license associated with the file (by mapping that file to
the subpackage and from there to the license for that subpackage).

For the most part, I've been able to figure this out, but there are some
files in PyXML that have defied any such mapping.

Any ideas on how I should proceed?

Thanks,

Tom

My guess is that this comes form the -isysroot option.

This option does not come from PyXML, nor does it come from stock
Python 2.4, so I guess it is something that the Universal Binary
added. You should ask on the python-mac list for advice.

Martin

You should ask on this list which specific files you are interested
in.

.NET webservice ws 2004 digital signature and soap


Hello,

I try to connect to .NET soap webservice. The messages must have a 
signature confirm to ws - security 2004 with
enveloping mode.
I tried to build it with ZSI, but i hang at the signature. After this i 
tried to us pyxmlsec which build a signature, but not confirm to the ws 
2004 standard.
Right now i try to do it by hand but i am still not able to get the 
right digest.

As a short explanation using following template:

<?xml version="1.0" encoding="UTF-8"?><soapenv:Envelope 
xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/"

These are all from 4DOM.

This was originally written by Lars Marius Garshol.
He did not state a specific license.

They are all licensed under the PSF license.

This is my work; I hereby license it under the Academic Free License,
