XHTML mobile profile transformer and cleaner for Python

Mobile phones, and especially mobile site validators, are very picky about the validy of XHTML. It must not be any XHTML, but special mobile profile XHTML. Also, search engines like Google, will punish you in the mobile search results if your site fails to conform to mobile profile.

This is especially troublesome if you display external content (RSS feeds, ATOM feeds) on your mobile site. Incoming HTML cannot be guaranteed to follow any specification.

To solve this problem, we have created gomobile.xhtmlmp Python library which helps you to transform any HTML to content to valid XHTML MP. The library is piloted on plonecommunity.mobi site which  uses aggregated content from varying sources. The library is based on lxml.html.Cleaner. The library is part of GoMobile project which aims to create world class Python mobile web development tools.

Highlights

  • Turn any incoming HTML/XHTML to mobile profile compatible
  • Enforce ALT text on images – especially useful for external tracking images (feedburner tracker). ALT texts are required by XHTML MP.
  • Protect against Cross-Site Scripting Attacks (XSS) and other nastiness, as provided by lxml.xhtml.clean
  • Unicode compliant – eats funky characters

As an example we integrated gomobile.xhtmlmp  to Feedfeeder Plone add-on product.

Enjoy.

Sharing RSS feeds from the feed reader

I am following pretty many good web technology blogs in my Google Reader. Compiling this RSS feed list has taken few hours and I’d like to share the fruits of my hard work. Luckily in our beautiful world of Web 2.0 this is easy.

  1. Use Google Reader Manage subscriptions -> Export function to export your RSS feed list in OPML format
  2. Upload this file to your server
  3. Install OPML Blogroll widget, by fabulous Sterling Camden, to WordPress
  4. That’s it!

You should see the results on the right —>

The next step is to get auto export URL (via Google API keys?) to Google Reader so that I don’t have to manually sync the OPML file on my server.

I also recommend sharing your RSS feed list in Share Your OPML service.
