Question

我有以下使用命名空间的XML文件。

当我使用以下php函数时，它不会返回aws的属性：Country Code

$xml = new SimpleXMLElement($response,null,false,
                            'http://awis.amazonaws.com/doc/2005-07-11')

所以我在想。如何提取国家/地区代码属性？我需要创建一个特殊功能吗？以下是返回curl调用的字符串。

<aws:UrlInfoResponse xmlns:aws="http://alexa.amazonaws.com/doc/2005-10-05/">
<aws:Response xmlns:aws="http://awis.amazonaws.com/doc/2005-07-11">
<aws:OperationRequest><aws:RequestId>e3459429-82f5-f598-0219-18a8056cad27</aws:RequestId>
</aws:OperationRequest>

<aws:UrlInfoResult>

<aws:Alexa>

<aws:TrafficData>
    <aws:DataUrl type="canonical">samplesite.com</aws:DataUrl>
    <aws:Rank>47216</aws:Rank>
      <aws:RankByCountry>
         <aws:Country Code="US">

            <aws:Rank>11438</aws:Rank>
            <aws:Contribution>
              <aws:PageViews>72.5%</aws:PageViews>
              <aws:Users>76.4%</aws:Users>
            </aws:Contribution>
      </aws:Country>
      <aws:Country Code="IN">
        <aws:Rank>45749</aws:Rank>
        <aws:Contribution>
          <aws:PageViews>17.0%</aws:PageViews>
          <aws:Users>7.5%</aws:Users>
        </aws:Contribution>
     </aws:Country>
    </aws:RankByCountry>
</aws:TrafficData>
</aws:Alexa>
</aws:UrlInfoResult>
</aws:Response>
</aws:UrlInfoResponse>

        echo $node->attributes()->Code . "\n";
