<p><strong>Usage example</strong>: <em>You have discovered a site that provides feeds which are hidden and inaccessible by normal means. You want your bridge to directly read the feeds and provide them via <strong>RSS-Bridge</strong></em></p>
|
||
<p>Find a <a href="#template">template</a> at the end of this file.</p>
|
||
<p><strong>Notice:</strong> For a standard feed only <code>collectData</code> need to be implemented. <code>collectData</code> should call <code>$this->collectExpandableDatas('your URI here');</code> to automatically load feed items and header data (will subsequently call <code>parseItem</code> for each item in the feed). You can limit the number of items to fetch by specifying an additional parameter for: <code>$this->collectExpandableDatas('your URI here', 10)</code> (limited to 10 items).</p>
|
||
<h2><a id="the-parseitem-method" href="#the-parseitem-method" class="Permalink" aria-hidden="true" title="Permalink">#</a>The <code>parseItem</code> method</h2>
|
||
<p>This method receives one item from the current feed and should return one <strong>RSS-Bridge</strong> item.
|
||
The default function does all the work to get the item data from the feed, whether it is RSS 1.0,
|
||
RSS 2.0 or Atom 1.0.</p>
|
||
<p><strong>Notice:</strong> The following code sample is just an example. Implementation depends on your requirements!</p>
|
||
<pre><code class="language-PHP">protected function parseItem(array $item)
|
||
{
|

$item['content'] = str_replace('rssbridge','RSS-Bridge',$item['content']);

return $item;
