Classe: RSSParser  - X-Ref

\ingroup XML

<p>This parser is a wrapper around the functionality provided by the MagpieRSS parser, which
can be found at http://magpierss.sourceforge.net/. The RSS parser is compatible with
RSS 0.9, 1.0 and almost all the modules of the 1.0 specification.</p>
<p>This object is exported to all templates so that we can easily incorporate the headlines
and/or the content of other pages in our journal. To do so, this object is exported with
"rss" as its identifier, so a simple operation to fetch the headlines from Slashdot would
look like:</p>

<pre>
{if $rss->parse("http://slashdot.org/slashdot.rdf")}
{foreach from=$rss->getItems() item=rssItem}
<a href="{$rssItem->getLink()}">{$rssItem->getTitle()}</a>
{/foreach}
{/if}
</pre>

<p>The parse() method takes a url as a parameter, and it will return true if the url
was correctly fetched. If so, we can then ask the parser to gives us an array of
RSSItem objects which contain information about all the different &lt;item&gt; tags that were
found in the RSS feed. So, the only thing we have to do now is iterate through the array using
Smarty's <i>{foreach ...}</i> construction and call the appropiate methods on the RSSItem object.</p>
<p>To get more information about the channel (whatever was found between the &lt;channel&gt; opening
and closing tag) we can call the getChannel() function and we will get a nice and ready RSSChannel
information that we need to know.</p>
<p>If the RSS parser has been disabled via the configuration file, then the constructor will not do
anything and the parse method will return false.</p>
