  </air:AirPricingInfo>

我在上面给出了xml，我的任务是从“TaxInfo”中打印类别和金额。

我无法获取 Taxinfo 属性，例如类别和金额

foreach ($Results->children('air', true) as $price) {
 if (strcmp($price->getName(), 'AirPricingInfo') == 0) {
   foreach($price->children('air', true) as $tax){
    print_r($tax->TaxInfo);
   }
  }
}

【解决方案1】：

您可以做的是使用foreach 循环遍历$Results 并使用getName 检查每个SimpleXMLElement 的名称。如果匹配，您可以从属性中获取Category 和Amount。

例如：

$source = <<<SOURCE
<air:AirPricingInfo Key="J2GiU97Q2BKABKe1AAAAAA==" TotalPrice="USD663.70" BasePrice="GBP233.00" ApproximateTotalPrice="USD663.70" ApproximateBasePrice="USD310.00" EquivalentBasePrice="USD310.00" ApproximateTaxes="USD353.70" Taxes="USD353.70" LatestTicketingTime="2017-11-06T23:59:00.000-05:00" PricingMethod="Auto" Refundable="true" IncludesVAT="false" PlatingCarrier="WY" ProviderCode="1V">

</air:AirPricingInfo>
SOURCE;

$Results = simplexml_load_string($source);

foreach($Results as $elm) {
    if ($elm->getName() === "air:TaxInfo") {
        $category = (string)$elm->attributes()->Category;
        $amount = (string)$elm->attributes()->Amount;
        echo $category, " ", $amount, PHP_EOL;
    }
}

将导致：

GB USD99.80
UB USD17.80
I2 USD5.20
OM USD5.20
AE USD20.40
F6 USD9.50
TP USD1.40
ZR USD1.40
YQ USD193.00
