Question

我正在使用雅虎天气API来获取我所在地区的天气。我从API的调用中得到了一个XML文档。我尝试了以下方法来访问元素中的属性：yweather：condition＆＃39;没有成功。我正试图访问“临时”＃在这个元素中。我收到以下错误：

＆＃39;语法错误，意外＆＃39;：＆＃39;排队......

 $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;
