Mashup question
9 August 2007 at 10:36pm Last edited: 9 August 2007 11:10pm
I want to integrate the weather from yahoo into my site.
http://xml.weather.yahoo.com/forecastrss?u=C&p=AUXX0118The 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 trunk of mashups module 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.
