TalkPHP - View Single Post - Parse XML categories and create RSS feed out of it...

Here's just one idea. The process is simply: find items which don't belong to our requested category and delete them.

PHP Code:


			
/**
 * Filtering an RSS feed by category.
 */

// Load the XML feed
$dom = new DOMDocument();
$dom->load('http://www.talkphp.com/external.php?type=RSS2');


// Query for the items we want to throw away
$xpath = new DOMXPath($dom);
$nodes = $xpath->query('//item[not(category = "General")]');

// Remove those unwanted items
foreach ($nodes as $node)
{
    $node->parentNode->removeChild($node);
}

// Output the filtered document
header('Content-Type: application/xml; charset='.$dom->encoding);
echo $dom->saveXML();
