Class Details



[line 74]

RSS uses XSLT and Cache to generate content syndicated from other web

sites and to cache it so as not to put unnecessarily load on those  sites.  RSS also exposes an EasyText method, which adds support for the  EasyText =RSS tag.  Please note: this class depends on the Cache and  XSLT classes.
New in 1.2: 
  • Added the ability to create RSS documents instead of simply processing them.
   This is compatible with RSS version 0.91, but I don't know about 1.0.
  New in 1.4: 
  • Fixed a bug in the EasyText method (stupid spelling mistake!).  Thanks Oleg
   for the report!
  New in 1.6: 
  • Removed the EasyText() and EasyTextInit() methods.

5      $url = 'http://somesite.com/content.rss';
6      $rss_content = $rss->getUrl ($url);
7      $stylesheet = $rss->getXsl ('inc/xsl/somesite.xsl');

$xslt = 

	
[line 86]

  This is an XSLT processor resource returned by the

xslt_create () function.  Please note: the XSLT processor  is not created until the process method of this class is  called, so as to maintain compatibility with systems that  do not have Sablotron support installed, but are using  EasyText.
