Parse weather data from Weatherbug in PHP

Question

Greetings,

I am trying to parse live weather data from Weatherbug's RSS feed in PHP. I had previously used simplexml_load_string() with NOAA's weather data but I cannot figure out how to output the data that I need from Weatherbug.

Here is the XML for current conditions:

    <rss version="2.0" xmlns:georss="http://www.georss.org/georss">
 <channel>

        <title>Observations from Saint Inigoes,  MD - USA</title>


     <link>http://weather.weatherbug.com/MD/Saint Inigoes-weather.html?ZCode=Z5546&amp;Units=0&amp;stat=KNUI</link>
     <description>Weatherbug, the owner of the world's largest weather network is now providing an API to it's weather data in the form of RSS. This will enable it's enthusiastic users to build their own applications.</description>

    </rss>

The part that I most need is <description> under <item>. Any help would be greatly appreciated!

Try this:

$description = (string)$simpleXml->channel->item->description;
