從XML屬性提取數據並在foreach中循環

Question

我無法讓此foreach循環。 它只是返回第一個值，樂高。 我如何使其循環並返回樂高玩具和playmobil。

XML

<product product-id="000000000100165001">
    <customattributes>
        <customattribute attributeid="brand1">lego</customattribute>
        <customattribute attributeid="isBulky">false</customattribute>
        <customattribute attributeid="isDropShip">false</customattribute>
    </customattributes> 
</product>
<product product-id="000000000100164001">
    <customattributes>
        <customattribute attributeid="brand1">playmobil</customattribute>
        <customattribute attributeid="isBulky">false</customattribute>
        <customattribute attributeid="isDropShip">false</customattribute>
    </customattributes> 
</product>

PHP

foreach ($xml->product->customattributes->customattribute as $rating) {
  switch((string) $rating['attributeid']) { // Get attributes as element indices
    case 'brand1':
      echo $rating;
      break;
  }
}

Answer 1

當您訪問$xml->product->customattributes ，語法是$xml->product[0]->customattributes 。 也就是說，您只循環了第一個產品的<customattribute>標簽。

如果要循環兩種產品及其屬性上，你需要使用兩個循環：

foreach ($xml->product as $product) {
  foreach ($product->customattributes->customattribute as $rating) {
  ...
