【问题描述】：

尝试使用 SimpleXML 函数进行解析，该函数运行良好。但我一直坚持如何从 XML 中提取“颜色”和“长度”数据

下面是代码中引用的“ebay-response.xml”文件的sn-p：

完整的xml文件可以从ebay-response.xml下载

我当前的 PHP 脚本是：

if(!$resp = simplexml_load_file("ebay-response.xml"))
{
echo "Unable to load XML Stream from eBAY API, possible no response from eBay?<br />\n";
    return;
}

if ($resp->Ack != "Success") {
echo 'eBay Response Status was: ' . $resp->Ack . " Unable to parse the XML <br />\n";
    return;
}

echo 'eBay Response Status: ' . $resp->Ack . "<br />\n";
echo 'ebay Response Timestamp: ' . $resp->Timestamp . "<br />\n";
echo 'ebay API Version: ' . $resp->Version . "<br />\n";
echo 'ebay API Build: ' . $resp->Build . "<br />\n";

echo 'eBay Item Title: ' . $resp->Item->Title . "<br />\n";
echo 'Total Items (all variations): ' . $resp->Item->Quantity . "<br />\n<br />\n";

foreach( $resp->Item->Variations->children() as $SkuAndQuantity )
{
echo 'Title: ' . $resp->Item->Title . ' SKU: ' . $SkuAndQuantity->SKU .
         ' Qty: ' . $SkuAndQuantity->Quantity . "<br />\n";
    foreach( $resp->Item->Variations->Variation->VariationSpecifics->NameValueList->children() as $options )
{
echo $options .'<br />';
}
}
echo "<br />\n";

我在运行我的代码时得到的结果如下所示，如您所见，我似乎只拉回白色（并且没有长度），即使使用这种颜色，我似乎也只是从第一个开始获得颜色“变体”元素

【解决方案1】：

XML 允许以分层方式表示数据，也可以表示为某种树。

在 ebay 答案中，您有一个 <Item> 元素。

<Item> 元素可以有一个<Variations> 元素。

<Variations> 元素可以有零个或多个<Variation> 元素。

<Variantion> 元素又可以在零个或多个 <VariationSpecifics> <NameValueList> 元素中包含 <Name>/<Value> 对。

<GetItemResponse>
  <Item> (1)
    <Variations> (1)
      <Variation> (1..n)
        <VariationSpecifics> (1)
          <NameValueList>  (1..n)
            <Name> (1)
            <Value> (1)

对于可以包含多个条目 (1..n) 的元素，您需要对其进行迭代。

以下是纯文本输出的这种迭代示例（因为它更容易用于演示目的）：

$xml = simplexml_load_file('ebay-response.xml');
$item = $xml->Item; // one <Item>
$variations = $item->Variations->Variation; // one or more <Variation>

echo $item->Title, "\n";
echo str_repeat('=', strlen($item->Title)), "\n";

foreach ($variations as $variation) {
    echo " * ";
    $nameValues = new CachingIterator(new IteratorIterator($variation->VariationSpecifics->NameValueList));
    foreach ($nameValues as $pair) {
        echo $pair->Name, ': ', $pair->Value, $nameValues->hasNext() ? '; ' : ' ';
    }
    echo '(SKU: ', $variation->SKU, ')', "\n";
}

这表明您需要将多个 foreach'es 相互堆叠。这是两个 - 因为在上面的架构中有两个用 (1..n) 标记的元素。

内部 foreach 有点特别，因为我将 <NameValueList> 元素包装在 CachingIterator 中。那一个添加了一个很好的方法，您可以询问 foreach 循环中是否会有下一个元素 ($nameValues->hasNext())，该元素在示例中用于用分号 (";") 分隔名称/值对。

示例（缩短）输出是：

CLOSED END ZIPS 40 Colours 4  6  8 10 12in (10-30cm) for Skirt Trousers Craft
=============================================================================
 * Colour: White; Length: 4" (10cm) (SKU: 1176:3448)
 * Colour: White; Length: 5" (12cm) (SKU: 1176:3449)
 * Colour: White; Length: 6" (15cm) (SKU: 1176:3450)
...
 * Colour: Dark Grey; Length: 6" (15cm) (SKU: 1213:3450)
 * Colour: Dark Grey; Length: 7" (18cm) (SKU: 1213:3451)
 * Colour: Dark Grey; Length: 8" (20cm) (SKU: 1213:3452)

现在这并不总是您想要的显示。例如，您可能希望列出所有颜色，并为每种颜色显示可用尺寸。这将变得过于复杂，因为你在 SimpleXMLElement 上进行了 foreach'ing。 foreach 的替代方法是运行一个或多个 xpath 查询，您可以在其结果上再次 foreach。

这是另一个按颜色列出所有长度的示例：

$item->registerXPathNamespace('xs', 'urn:ebay:apis:eBLBaseComponents');
$colors  = $item->xpath('xs:Variations//xs:Value[preceding-sibling::xs:Name = "Colour"]');
$colors  = array_unique(array_map('trim', $colors));

foreach($colors as $color) {
    echo " * Color ", $color, ": ";
    $colorLengths = $item->xpath(sprintf(
        '  xs:Variations
             //xs:Value [. = %s and preceding-sibling::xs:Name = "Colour"]
         /../..//xs:Value [preceding-sibling::xs:Name = "Length"]', xpath_string($color)));
    $count = count($colorLengths);
    echo "$count Lengths: ";
    foreach ($colorLengths as $i => $length) {
        $hasNext = $count - $i - 1;
        $length->registerXPathNamespace('xs', 'urn:ebay:apis:eBLBaseComponents');
        echo $length, ' (SKU: ', $length->xpath('../../../xs:SKU')[0], ')', $hasNext ? '; ' : '';
    }
    echo "\n";
}

示例输出：

【讨论】：

hakre - 非常感谢您提供非常详细的解释。今天晚上我会看看你的一些代码。 $nameValues->hasNext() 看起来特别有趣，因为虽然提供的示例 xml 总是有两个变体（颜色和长度），但我肯定会不得不处理不同数量的产品变体。你提供的第二段代码看起来也很有趣，不能说我现在有它的用处......但我相信随着我深入到我的项目中会突然出现一些东西:)
PHP 的迭代器总是让我感到困惑（IteratorIterator！？），但 CachingIterator 的技巧看起来非常巧妙。 :)

【解决方案2】：

这部分代码不会遍历 Variation 或 NameValueList 元素：

foreach($resp->Item->Variations->Variation->VariationSpecifics->NameValueList->children() as $options)
{
  echo $options .'<br />';
}

它将始终使用内部的第一个 Variation 元素和第一个 NameValueList 元素。这会导致您的问题。

您需要将代码更改为：

foreach($resp->Item->Variations->children() as $Variation)
{
  echo 'Title: ' . $resp->Item->Title . ' SKU: ' . $Variation->SKU .' Qty: ' . $Variation->Quantity .'<br />';
  foreach($Variation->VariationSpecifics->children() as $NameValueList)
    foreach($NameValueList->children() as $option)
      echo $option .'<br />';           
}
