How to parse RSS...

[CrazeD]

This is something I've been wanting/trying to do for quite a while now. It always intimidated me so I just didn't bother looking into it much. However this is something I need to add to my site now, so I need to learn how to do that.

 

I've Googled it many times looking for tutorials and whatnot, and no solution so far has actually worked. I've tried pre-made scripts that all I had to do was add the URL, and they didn't work for me.

 

So, I come here now and ask: what is the simplest way to parse an RSS feed to display the contents on my webpage? Will one script work for every RSS feed, or does it have to be fine-tuned to each different feed?

 

Please don't tell me to just go search as I've already done that and can't find what I need.

 

Thanks.

Use SimpleXML.

 

<?php
$rss = new SimpleXMLElement('http://www.phpfreaks.com/forums/index.php?type=rss;action=.xml', null, true);

echo "<ul>\n";
foreach ($rss->channel->item as $item) {
echo "\t<li><a href='{$item->link}'>{$item->title}</a></li>\n";
}
echo '</ul>';
?>

 

Output (currently):

<ul>
<li><a href='http://www.phpfreaks.com/forums/index.php/topic,188668.msg846635.html#msg846635'>Re: Backup Restore time-out</a></li>

Is there any PHP4 alternatives?

 

I found this but couldn't get it to work. It worked fine on with the example.xml that he made, but doesn't work with any URL's, I just get a blank page.

 

Here is the code I'm accessing it with:

 

<?php
require ('xml_parse.php');


$xml = file_get_contents('http://www.phpfreaks.com/forums/index.php?type=rss;action=.xml');
$parser = new XMLParser($xml);
$parser->Parse();

echo $parser->document->item[0]->title[0]->tagData;

?>

 

Thanks.
