Atom feeds with PHP 5 Dom and XSL January 13, 2008
Posted by idimmu in php.All blogs require silly amounts of feed generators, right? And this is a silly blog so requires a silly generator. The entire site is written using PHP5, and my automagic 'datahandler' activepage concept creates an XML document using DOM that then uses XSL as a templating engine, so I figured it wouldn't be too hard to knock up a stylesheet to turn the default datahandler for the blog in to a nice atom feed! Just make sure you set the content-type to application/atom+xml when generate the page!
