I want to integrate the weather from yahoo into my site.
http://xml.weather.yahoo.com/forecastrss?u=C&p=AUXX0118

The problem is that <yweather:condition text="Partly Cloudy" code="30" temp="15" date="Thu, 09 Aug 2007 10:55 am CEST" /> is not imported because of the ':'

Does someone know how to read element with column in SimpleXMLElement?

Is there a way to cash the output?

Freeyland, if you want to read namespaced elements (qname) best practice would be to use Xpath. You could try out some query such as ;

$conditions = $xml->xpath("//yweather:condition");

But to make the whole process easy I've made an update to the mashups module which could handle such feeds. You can download the latest build in the [url =http://open.silverstripe.com/browser/modules/mashups/trunk]trunk of mashups module[/url] and try out the following code. This will fetch the attribute values of condition tag in Yahoo Weather feed.

In your controller;

function YahooWeather(){
      $yw = new RestfulService("http://weather.yahooapis.com/forecastrss");
      $params = array(
            "u" => "c",
            "p" => "USIL0225"
         );
      $yw->setQueryString($params);
      $conn = $yw->connect();
      $result = $yw->searchAttributes($conn, "//yweather:condition");
      
      return $result;
   }

and in the template;
[html]
<% control YahooWeather %>
   <p>weather conditions for $date<br/>
    $text - tempreature -$temp</p>
<% end_control %>
[/html]

Hope this helps :)

Currently Mashups module doesn't support caching, but it's something on the road maps for future releases.
