Question

我正在使用房地产API编写一个简单的应用程序。这是我第一次使用api，这是我第一次使用xml。

我想我错过了xml文件中的范围，但我不确定。我想要实现的目标是回应城市名称

This XML file does not appear to have any style information associated with it. The document tree is shown below.
<TruliaWebServices>

</heatMapURL>
</location>
<listingStats/>
</TruliaStats>
</response>
</TruliaWebServices>

这是我的PHP代码。

<?php 
        $url = "http://api.trulia.com/webservices.php?library=TruliaStats&function=getCityStats%20&city=San%20Diego=CA&state=CA&startDate=2014-05-06&endDate=2014-09-03&statType=listings&apikey=ssssssssssssssss";
        $xml = simplexml_load_file($url);
        echo $xml->TruliaWebServices->response->TruliaStats->location->city;


?>

Answer 1

只需从回声中删除根节点（TruliaWebServices），这是不需要的。

print_r($xml->response->TruliaStats->location->city);  // San Diego

用php访问xml数据很困难
