URL이있는 노드에 액세스하는 방법은 무엇입니까?

Question

PHP 루프를 통해 구문 분석하려고하는 날씨 xml이 있습니다. 문제는 내가이 노드를 드릴 다운 할 수

<aws:weather xmlns:aws="http://www.aws.com/aws> 

를 제외한 모든 노드에 액세스 할 수 있음이다. 그것은 URL 때문입니까?

<?php 
$html = ""; 
$url = "http://i.wxbug.net/REST/SP/" . 
     "getLiveWeatherRSS.aspx?api_key=sdfgdsgd5454&stationid=SLNAS"; 
$xml = simplexml_load_file($url); 
for ($i = 0; $i < 10; $i++) { 
$aws:station = $xml->channel->aws:weather->aws:ob[$i]->aws:station; 
$html .= "<h3>$aws:station</h3>"; 
} 
echo $html; 
?> 

이 문제는 AWS 네임 스페이스에 의해 발생

Answer 1

는 XML은 다음과 같습니다 나는 ultimatly이 내가 가지고있는 PHP이다이 노드를

<aws:station> Salinas Municipal Airport <aws:station> 

에 접근 할 필요가 XML 문서

<aws:weather xmlns:aws="http://www.aws.com/aws"> 

당신은 그 접근보다, 네임 스페이스에 속한 모든 노드를 가져 오도록 childeren 방법을 사용할 수 있습니다.
