Re: Deploying on Windows servers : advice sought a module
At my work place I still use py2exe but I do not rely on its automatic discovery and packaging. The setup.py lists all the dependencies explicitly in packages and includes parameters. These end up in library.zip. Then the source file paths with the actual business logic are gathered with os.walk and passed in as data_files parameter. Finally the actual service executable is generated from the very minimal script. This executable is registered only once and as long as you do not move it to a different directory Windows will find it and start it up for you. The service script that gets used by py2exe is truly minimal. It just changes working directory to where the executable sits, adds current directory to the sys.path and loads the main script. The main script would be copied by setup.py into the current working directory. When there is a new release I update the files with business logic and restart the service. When I want to update the dependent libraries I regenerate library.zip, copy it over and again restart the service. The trick is to let the files from the current directory to be imported first. To achieve it you should avoid putting your business logic files into your library.zip. py2exe will do it if you let it to. Depending on situation I go to into dirty tricks like selectively commenting out import statements before running py2exe or even post-processing library.zip and deleting the business logic files from the archive. With a little bit of care you can make it work but I admit my approach is not very clean. Oh another trick I have learned. If your service does not start because let's say an import has failed look into Event Viewer/Application. There should be an entry with a nice traceback listing what went wrong.

You have to remember that endElement is being called on the end of every element. In your case it is called by /description but the parser did not see coordinates yet. In def characters you should be collecting the ch in a buffer. It may be called multiple times for the same element. Something like self.description += ch would do for starters.

It looks like you have three tasks here: - get data - parse it - store it SOAP could be the means to accomplish only the first one. If the service you use exposes the functionality using XML-RPC or some REST-ful methods I would try them first. If it does not, then you are stuck with SOAP. Using SOAP in Python is currently not as straightforward as it could be. You have chosen to use ZSI and that is fine choice. In documentation look for wsdl2py. Given a URL to a WSDL file it will generate stub class definition with methods corresponding to the SOAP service methods. In your code you would instantiate the class, call the method you want and grab the payload. Your first task is done. From what I understand the payload will be XML that will need to be parsed. For that you could use the excellent ElementTree If I were you I would investigate suds (https://fedorahosted.org/suds) It promises to be easier to use than ZSI. The README has the usage example.

It is not even legal xml.

Re: Advice for editing xml file using ElementTree and wxPython

Seems like this is something that's probably pretty common, modifying

about this and has some good advice about best practices here.
The trick is to keep a reference to the actual ElementTree objects
as you build your TreeCtrl. Ability to store arbitrary Python object
in the TreeCtrl Item makes it easy. In an event handler modify the
original element and you are done. Do not forget to save when
closing.
If the XML file is very large you may have performance issues since
the whole parsed tree is kept in memory. Luckily the ElementTree
representation is lean.
A sample below shows the approach. It is very basic but I hope it
conveys the idea. Please note that edits to the actual tags are
ignored.

Consider using ODBC. mxODBC as well as pyodbc and ceODBC could be good alternatives. * Easy GUI creation. Solved using PyQt. * Cross Platform (Linux + Windows).

But I was not yet able to find a solution for the report generation. What we would like to have is a sort of GUI interface to prepare the reports without having to code the positioning. I found reportlab, and it looks like it can do all that is needed in terms of output. But you still have to code the report. And this is a no go. In context, I found RML and saw links to graphical RML editors. But I have not yet found a concrete example code, or documentation. What am I missing? Is RML a reportlab creation or is it a recognised open standard? If not, is there an open standard, that is easily to process with python? I still have to try it but pisa looks very promising: http://pisa.spirito.de/content/501/pisa3.html PDF generation using HTML+CSS for layout. I hope your boss considers HTML acceptable coding.
