Example for the usage of PyXB and Django.
If you are new to the subject of XSD, WADL and XML, I suggest reading the blog: Thomas Nurkiewic, 2012
"In principle WADL is similar to WSDL, but the structure of the language is much different. Whilst WSDL defines a flat list of messages and operations either consuming or producing some of them, WADL emphasizes the hierarchical nature of RESTful web services. In REST, the primary artifact is the resource. Each resource (noun) is represented as an URI. Every resource can define both CRUD operations (verbs, implemented as HTTP methods) and nested resources. The nested resource has a strong relationship with a parent resource, typically representing an ownership."
We use PyXB to generate a generic "wadl.py" file for the XML Schema validation of related XML file "wadl.xml" documents via django.
Basis for the validation is the XML Schema described in "wadl.xsd". It functions as our basis for the generated "wadl.py" file. And then "po.xml" files can be entered and checked in our webservice admin interface.
- git clone https://github.com/dkdndes/validatexsd.git
- cd validatexsd
- virtualenv env
- source env/bin/activate
- pip install -f requirements.txt
- python manage.py check
- python manage.py migrate
- python manage.py makemigrations
- python manage.py runserver 0:8000
You can regenerate a alternative "wadl.py" fiel within the "webservicedocs" directory with the following command:
- pyxbgen -u wadl.xsd -m wadl
Now test it with a valid XML file "wadl.xml" and start changing tags, etc.
You find xsd/xml examples in the pyxb repository
Have fun!
