RSS Generator Source Code

The RSS Generator is another application based on the file menu.xml. The application reads through the file taking the relevant items and adds them to a dom object before converting it to XML.

Part of rssGenerator.php showing the php code:

<?php

// Create new dom object
$dom = new DomDocument('1.0', 'utf-8');

// Create the RSS element
$rss = $dom->appendChild(new DOMElement('rss'));
$rss->setAttributeNode(new DOMAttr('version', '2.0'));

// Add the channel to hold all the feeds
$channel = $rss->appendChild(new DOMElement('channel'));

// Create main channel items:
// Main feed title
$title = $channel->appendChild($dom->createElement('title'));
$title->appendChild($dom->createTextNode("Barnaby Norman's Web Portfolio")); 

// Main feed home page link
$link = $channel->appendChild($dom->createElement('link'));
$link->appendChild($dom->createTextNode("http://www.deta-it.co.uk/")); 

// Main feed site description
$description = $channel->appendChild($dom->createElement('description'));
$description->appendChild($dom->createTextNode("A website designed to highlight significance and expertise in areas of the work of Barnaby Norman")); 

// Main feed language
$language = $channel->appendChild($dom->createElement('language'));
$language->appendChild($dom->createTextNode("en-uk")); 

// Load the xml from the menu xml file
$xml = simplexml_load_file("../siteStuff/menu.xml");

// Loop through the xml adding text nodes to the channel object
foreach($xml->menuItem as $xmlItem)
{
    $subXml = $xmlItem;

    foreach($subXml->menuItem as $subItem)
    {        
        // Create item for each sub xml item
        $item = $channel->appendChild($dom->createElement('item'));

        // Title
        $title = $item->appendChild($dom->createElement('title'));
        $title->appendChild($dom->createTextNode($subItem->title->a)); 

        // Link
        $link = $item->appendChild($dom->createElement('link'));
        $link->appendChild($dom->createTextNode("http://www.deta-it.co.uk" . $subItem->title->a->attributes())); 

        //Test for description and add if available
        if($subItem->description)
        {
            $description = $item->appendChild($dom->createElement('description'));
            $description->appendChild($dom->createTextNode($subItem->description));
        }

        // Published date and time
        $pubDate = $item->appendChild($dom->createElement('pubDate'));
        $pubDate->appendChild($dom->createTextNode($subItem->lastmod)); 
    }
}

// Convert the dom object into xml
$dom->formatOutput = true; 
$xmlSitemap = $dom->saveXML();

// Write to a file
$file = fopen("rss.xml", "w");
fwrite($file, $xmlSitemap);
fclose($file);

// Present to display
echo "<pre class=\"code\">" . htmlentities($xmlSitemap) . "</pre>";
