Php Expedia API请求返回XML结果，但可以'；我们不能从中提取数据

我不知道为什么，也许我太傻了，但我已经尝试从Expedia API请求中提取内容超过2个小时了。也许我今天在这个网站上工作了很长时间，所以我没有看到一个简单的错误，但无论如何我没有找到它。API请求“HotelList”给我带来了这个问题，获取HotelDetails并从返回的XML输出中提取数据在第一次尝试时效果很好

我收到的请求/结果如下所示：

$result = $search->getHotels($dataArray);

echo $result->hotels->HotelList->HotelSummary[0]->name;
echo $result->HotelList->HotelSummary[0]->name;
echo $result->$HotelSummary[0]->name; or
echo $result->current_search->check_in;

我一直在想尽一切办法弄清楚这家酒店的名字，但我甚至无法提取退票结果或类似的信息。我只是在尝试这样的东西：

$result = $search->getHotels($dataArray);

echo $result->hotels->HotelList->HotelSummary[0]->name;
echo $result->HotelList->HotelSummary[0]->name;
echo $result->$HotelSummary[0]->name; or
echo $result->current_search->check_in;

可能像其他20种组合，但根本没有输出

我真的希望有人能帮我

它看起来像：

$result['hotels']->HotelList->HotelSummary[0]->name
但是obv.未经测试。
您能提供一个原始xml的示例吗？如果您也能看到完整的simplexml请求代码，那就太好了。这可能很简单/很明显，但我今天脑子不好使，所以我想亲自动手测试一下，让它和密使一起工作，但非常感谢你的努力：）-可能重复：先生，你和密使是我的英雄。我生命中该死的三个小时，我不明白为什么我可以得到零输出。出于彻底的绝望，我搜索了SimpleXMLObject和HotelList，并偶然发现了这一点。多么令人难以置信的沮丧，终于解决了…非常感谢你，使者，我只是没见过，但现在它像一个符咒一样工作！！：）当然，谢谢你的努力，戴夫。
