WSGI.xml

[http://cheeseshop.python.org/pypi/wsgixml/ This package] contains some WSGI components of particular interest to those using XML in their Web applications in some way. The components included in this release are:

applyxslt - WSGI middleware for applying XSLT to an XML response body if needed (i.e. if the response is XML with a stylesheet PI and the browser is not known to support XSLT)
safexhtml - Middleware that checks for XHTML capability in the client and translates XHTML to HTML if the client can't handle it

For more on WSGI middleware see: [http://www-128.ibm.com/developerworks/web/library/wa-wsgi/ "Mix and match Web components with Python WSGI"]

Example

You use WSGI middleware by wrapping up your WSGI application implementation. WSGI-aware frameworks such as [http://pylonshq.com/ Pylons] and [http://www.cherrypy.org/ CherryPy] make this easy, but in the following example I use the basic [http://cheeseshop.python.org/pypi/wsgiref wsgiref] server implementation.

from wsgiref.simple_server import make_server
from wsgixml.safexhtml import safexhtml

def app(environ, start_response):
    #... app logic here
    return [XHTML]

httpd = make_server('', PORT, safexhtml(app))
print 'Starting up HTTP server on port %i...'%PORT

# Respond to requests until process is killed
httpd.serve_forever()

Installation

WSGI.xml requires Python 2.4 or more recent and [/FrontPage 4Suite-XML 1.0rc4] or more recent. The easiest way to install it is:

easy_install wsgixml

If this doesn't work you're probably not set up for easy_install and I suggest you follow [http://peak.telecommunity.com/DevCenter/EasyInstall these simple instructions]. easy_install will automatically take care of installing dependencies for you.
