in your framework. Note: you need to use the gevent python WSGI server to use gevent- socketio. Namespaces: since you mostly have one websocket/socket.io endpoint per website, it is important to be able site, just like you need routes to map URLs to different parts of your code. The Socket.IO 0.7+ namespaces are a welcome addition, and if you don’t use Socket.IO, you’ll probably end-up writing your own are stateful (like a Websocket), and exposes the same functionality for all. You can have many namespaces inside a Socket, each delimited by their name like /chat, /filesystem or /foobar. Note also that

Example: itertag = 'product' namespaces A list of (prefix, uri) tuples which define the namespaces available in that document that will be processed with this spider automatically register namespaces using the register_namespace() method. You can then specify nodes with namespaces in the itertag attribute. Example: class YourSpider(XMLFeedSpider): namespaces = [('n', selectors also support some EXSLT [http://www.exslt.org/] extensions and come with these pre-registered namespaces to use in XPath expressions: prefix namespace usage re http://exslt.org/regular-expressions regular
