I'm trying to create my own RSS feed (learning purposes) using `simplexml_load_string` while parsing `http://uk.news.yahoo.com/rss` in PHP. I get stuck at reading the HTML tags inside the `<description>` tag.

My code so far looks like this:

```
$feed = file_get_contents('http://uk.news.yahoo.com/rss');
$rss = simplexml_load_string($feed);

//for each element in the feed
foreach ($rss->channel->item as $item) {
    echo '<h3>'. $item->title . '</h3>'; 

        foreach($item->description as $desc){

             //how to read the href from the a tag???

             //this does not work at all
             $tags = $item->xpath('//a');
             foreach ($tags as $tag) {
                 echo $tag['href'];
             }
       }
}

```

Any ideas how to extract each HTML tag?

Thanks
