Question

我长期以来一直对这个问题感到难过，并希望有人可以提供帮助。这是我第一次通过Xpath方法解析SOAP。我有Bing的Geo Locations数据集，我试图迭代并写入MYSQL表。我正在迭代的XML文件看起来像这样：

<?xml version="1.0" encoding="utf-8"?>

我的php代码如下所示：

$file = 'soap-example-2.xml';
$xml = simplexml_load_file($file, NULL, NULL, "http://schemas.xmlsoap.org/soap/envelope/");
$xml->registerXPathNamespace('s', 'http://schemas.xmlsoap.org/soap/envelope/');
$xml->registerXPathNamespace('a', 'http://schemas.datacontract.org/2004/07/Microsoft.BingAds.Advertiser.CampaignManagement.MT.Messages');
$xml->registerXPathNamespace('i', 'http://www.w3.org/2001/XMLSchema-instance');
$xml->registerXPathNamespace('b', 'http://schemas.datacontract.org/2004/07/Microsoft.BingAds.Advertiser.CampaignManagement.MT.Entities');

$num_rows = count($xml->xpath('//b:Country/b:SubGeographyAreas/b:SubGeography/b:MetroAreas/b:MetroArea/b:Cities/b:City'));
echo $num_rows;

foreach($xml->xpath('//b:Country/b:SubGeographyAreas/b:SubGeography/b:MetroAreas/b:MetroArea/b:Cities/b:City') as $city)
{
    for ($i=0; $i < $num_rows; $i++) { 
        echo $city->Name[$i];
    }
}

我无法通过城市节点回响所有城市的孩子。在我上面的php中，我只想回应每个城市名称。如果它正常工作，它会回应这个：

任何帮助将不胜感激！我确信这是一个我忽略的简单事情。

我没有看到内部for循环的目的。每个城市只有一个Name，对吗？你试过这个：

$bNs = 'http://schemas.datacontract.org/2004/07/Microsoft.BingAds.Advertiser.CampaignManagement.MT.Entities';
$cityPath = '//b:Country/b:SubGeographyAreas/b:SubGeography/b:MetroAreas/b:MetroArea/b:Cities/b:City';
foreach($xml->xpath($cityPath) as $city)
{
    echo $city->children($bNs)->Name;
}

无法使用PHP在XML Soap文件中循环遍历子项
