# NewsParserX - for MODx 0.9.x
# Version 0.9 - 2006-04-02
# By: OpenGeek - [email protected]
# RSS parser shamelessly adapted from the RSS_feed class
# see http://www.phpclasses.org/browse/package/1299.html
#
# This parser allows for more sorts of feeds 
# and by using a simple URL translation allows for parsing of URLs
# which use variables within the URL
# The class can also limit the number of items shown and show the image
# For interoperatebility, the same CSS classes are used
# as in rad's NewsParser snippet ;-)
# 
# usage:
# [[NewsParserX? &url=`http://modxcms.com/forums/index.php|xq|sa|xe|recent;type|xe|rss2;action|xe|.xml|xa|limit|xe|20`]]
# or:
# $modx->runSnippet('NewsParserX', array('url'=> 'http://modxcms.com/forums/index.php?sa=recent;type=rss2;action=.xml&limit=20'));
#
# Changes:
# 1. 2006-04-02: Removed htmlentities() call to allow complex URLs to operate properly.

 Version 2.0
 This script will parse a RSS/XML file that comes from a URL feed.
 It will return an HTML unordered list.

 Getting a feed from another web site, should be quick and simple. Any
 unneeded complications should be avoided. One feed processor from a
 large Content Management System written in PHP nearly got me kicked 
 off my server. It ran wild with overly complex coding and included 
 opening hundreds of objects in a loop and used the XML-DOM (ugh!).

 This is far simpler, faster and more reliable.

 There are several versions of RSS/RDF. However, in practical use
 most all feed implementations follow the same pattern: A publication link is
 contained within <item> tags and consists of a <title>, <link>, and
 a <description>. We tested feeds from many different sources using
 all flavors and versions and this class was able to parse all of them.
 
 Granted there are many options with version 1.0 (RDF). However,  
 the full RDF syntax and vocabulary are not needed in a feed. 
 All of the implementations we found that included RDF tags 
 really added very little to the feed and  were safely ignored. 

 Version 2.0 extends versions 0.9x by adding new tags. This presented
 no problems and this class can be extended to process those tags. But 
 our goal was to provide a simple solution that can easily add syndicated
 publications to any web site.
 
  Changes: by Dr. Timothy Sakach
  1. 8/31/03 Corrected bug because the description tag (and all other tags, for that
     matter} can occur in any sequence within the container tags. 
  2. 8/31/03 Corrected bug created by the way the XML parser returns parsed cdata.
  3. 8/31/03 Added Set_Limit property to control the number of links to show.
  4. 8/31/03 Added image control and Show_Image property.
  5. 8/31/03 Channel, Image, and Items now use arrays as buffers.
