您好，我有一个 xml 提要，其中包含许多产品，每个产品都可以有多个 skus。我正在尝试遍历该 xml，然后如果找到 EAN 代码的匹配项，那么我将尝试将匹配的 skus 输出为单独的 xml 文件。

我到目前为止的代码如下，请你指出我哪里出错了，因为它还没有完全工作并且它输出一个空响应。

$ean = $_GET["ean"];
$trialXML = simplexml_load_file('trial.xml');

//function to lookup an EAN
function lookupEAN($ean,$xml) {

    //loop over products
    foreach($xml->products->product as $product) {
        //loop over individual skus
        foreach($product->sku as $sku) {
            if ($sku->ean == $ean) {  

                $skuData .= $sku;

            }
        }
    }
    return $skuData;
}

//lookup EAN
$response = lookupEAN($ean,$trialXML);

Header('Content-type: text/xml');
print_r($response);

这是来自 xml 的示例产品：

使用您想要的simplexml' withxpath to select the`node - 在 3 行代码中：

$xml = simplexml_load_string($x); // assume XML in $x
$sku = $xml->xpath("//sku[ean='$ean']")[0]; // select the 1st <sku> node with <ean> = $ean

echo htmlentities($sku->asXML()); // echo or save it as XML

看到它工作：http ://codepad.viper-7.com/F1FR2f

PHP < 5.4，例如：

$sku = $xml->xpath("//sku[ean='$ean']");
$sku = $sku[0];
