Question & Suggestion: May you add atom feed reader beside RSS reader?

[serkanalgur]

Hello there, Thank you for your small and such powerful framework. I use this framework to create simple sites/web-apps with ease. I have one suggestion.

Can you add atom reader beside RSS reader? I cloned RSS function and changed to atom reader. Here you go. I can create a pull request if you want to add this code to core.

	function atom($url,$max=10,$tags=NULL) {
		if (!$data=$this->request($url))
			return FALSE;
		// Suppress errors caused by invalid XML structures
		libxml_use_internal_errors(TRUE);
		$xml=simplexml_load_string($data['body'],
			NULL,LIBXML_NOBLANKS|LIBXML_NOERROR);
		if (!is_object($xml))
			return FALSE;
		$out=[];
		if (isset($xml->entry)) {
			$out['source']=(string)$xml->title;
			$max=min($max,count($xml->entry));
			for ($i=0;$i<$max;$i++) {
				$item=$xml->entry[$i];
				$list=[''=>NULL]+$item->getnamespaces(TRUE);
				$fields=[];
				foreach ($list as $ns=>$uri)
					foreach ($item->children($uri) as $key=>$val)
						$fields[$ns.($ns?':':'').$key]=(string)$val;
				$out['feed'][]=$fields;
			}
		}
		else
			return FALSE;
		Base::instance()->scrub($out,$tags);
		return $out;
	}
