从XML属性提取数据并在foreach中循环

Question

I am not able to get this foreach to loop. It is only returning the first value, lego. How can I make it loop and return both lego and 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;
  }
}

When you access $xml->product->customattributes , the syntax is short-hand for $xml->product[0]->customattributes . That is, you're only looping over the <customattribute> tags from the first product.

If you want to loop over both products and their attributes, you'll need to use two loops:

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