I am using yahoo weather API to get the weather for my locality. I get an XML document back from a call to the API. I have tried the following to access the properties in the element 'yweather:condition' with no success. I am trying to access the 'temp' in this element. I get the following error:
'syntax error, unexpected ':' in line ...
$endpoint = 'https://query.yahooapis.com/v1/public/yql?q=select%20*%20from%20weather.forecast%20where%20woeid%3D%20560743&diagnostics=true';
$xml = simplexml_load_file($endpoint) or die('failed to load xml');
$out = $xml -> diagnostics -> yweather:condition['temp'];
echo $out;
