Code:

$file = "http://au.rss.biz.yahoo.com/financenews/rss/financenews.xml";

$xml_prop = domxml_open_file($file);

$root = $xml_prop->document_element();

$nodes = $root->child_nodes();

$needed = 10;

$count = 0;

foreach($nodes as $node){

 if ($node->node_name()=='channel'){

 	$nodes2 = $node->child_nodes();

	foreach($nodes2 as $node2){

		if ($node2->node_name() == 'item'){

     		$nodes3 = $node2->child_nodes();

			foreach($nodes3 as $node3){

				if($node3->node_name()=='title')

					$title = $node3->get_content();

				if($node3->node_name()=='link')

					$link = $node3->get_content();				

			}			

			if($count<$needed){				

				echo $title;

				$count++;

			}	

		}

     }

  }

}

you can create coding like this:
if($xml_prop=domxml_open_file($file,DOMXML_LOAD_PARSING);
display content here ...
)
else
echo "";//display nothing, error will be hidden.

the remote file is slow to be loaded, it it is not complete and valid, errors could be displayed in browser.

you can create coding like this:
if($xml_prop=domxml_open_file($file,DOMXML_LOAD_PARSING);
display content here ...
)
else
echo "";//display nothing, error will be hidden. Posted by: exp

$xml->attributes()->q;

if attribute name is q and the current node is $xml, for example,

<link q="test"></link>

if your tag name contains something like - : you may need a special syntax to iterate the value.

foreach($xml->tag-name as $item){
echo $item->pbs:title;
}

The above does not work!

The correct one is:
foreach($xml->{'tag-name'} as $item){
echo $item->{'pbs:title'};
}

foreach($xml->children() as $name=>$node){
   echo $name."<br />";
   foreach($node->children() as $name2=>$title){
      echo $name."<br />";
      echo $title; 
   }
}

use the following loop to iterate something like this: In the title part, there is no more node. You can foreach more if there are more nodes.
