<p>A <em>Bridge</em> is a class that allows <strong>RSS-Bridge</strong> to create an RSS-feed from a website.
A <em>Bridge</em> represents one element on the <a href="../General/Screenshots.html">Welcome screen</a>
and covers one or more sites to return feeds for.
It is developed in a PHP file located in the <code>bridges/</code> folder (see <a href="../For_Developers/Folder_structure.html">Folder structure</a>)
and extends one of the base classes of <strong>RSS-Bridge</strong>:</p>
<table>
<thead>
<tr>
<th>Base class</th>
<th>Description</th>
</tr>
</thead>
<tbody>
<tr>
<td><a href="BridgeAbstract.html"><code>BridgeAbstract</code></a></td>
<td>This class is intended for standard <em>Bridges</em> that need to filter HTML pages for content.</td>
</tr>
<tr>
<td><a href="FeedExpander.html"><code>FeedExpander</code></a></td>
<td>This class is an extension of <code>HttpCachingBridgeAbstract</code>, designed to load existing feeds into <strong>RSS-Bridge</strong></td>
</tr>
<tr>
<td><a href="XPathAbstract.html"><code>XPathAbstract</code></a></td>
<td>This class is meant as an alternative base class for bridge implementations. It offers preliminary functionality for generating feeds based on <em>XPath expressions</em>.</td>
</tr>
</tbody>
</table>
