Question

我是PHP的新手。我有以下XML文件。我想解析组件。如您所见，此处重复了组件标记。我正在使用simplexml_load_string来获取HTTP请求的响应。此处重复此XML架构（<order> </order>）在此处重复。我想解析所有使用循环或直接访问。

<Order>
    <AmazonOrderID>406-6143419-7223518</AmazonOrderID>
    <MerchantOrderID>406-6143419-7223518</MerchantOrderID>
    <ShipmentID>DDNSkvgJN</ShipmentID>
    <MarketplaceName>Amazon.in</MarketplaceName>

        </Item>
    </Fulfillment>
</Order>

到目前为止，我已尝试过此代码：

$xml = simplexml_load_string($xmlDoc); 
foreach($xml->children() as $node) { 
  echo $node->AmazonOrderID . ", ";
  echo $node->ShipmentID . ", "; 
  echo $node->SKU . ", "; 
  echo $node->Component . "<br>"; 
}

Answer 1

我已将数据放入文件中，但这是对加载位的简单更改（我使用_file，而不是_string）但其余代码应该向您展示如何访问数据的层次结构。 ..

$xml = simplexml_load_file($url);
echo $xml->AmazonOrderID . ", ";
echo $xml->ShipmentID . ", ";
echo $xml->SKU . ", ";
foreach($xml->Fulfillment->Item as $item) {
    foreach ( $item->ItemPrice->Component as $component )   {
        echo "Type:".$component->Type." Amount:".$component->Amount.PHP_EOL;
    }
}

哪个给你......

406-6143419-7223518, DDNSkvgJN, , Type:Principal Amount:780.47
Type:Shipping Amount:13.02
Type:Tax Amount:174.78

Answer 2

您可以使用xpath方法轻松访问Component元素。

$components = $xml->xpath('Fulfillment/Item/ItemPrice/Component');
print_r($components);

那给你这个数组：

Array
(
    [0] => SimpleXMLElement Object
        (
            [Type] => Principal
            [Amount] => 780.47
        )

    [1] => SimpleXMLElement Object
        (
            [Type] => Shipping
            [Amount] => 13.02
        )

    [2] => SimpleXMLElement Object
        (
            [Type] => Tax
            [Amount] => 174.78
        )

)

使用循环或直接访问解析嵌套的xml simplexml_load_string / simple xml对象
