如何在库存可用性为“有库存”的list.phtml（Magento）中显示产品属性

Question

I have found this code:

$attributeCode = 'shoe_size';

$product = Mage::getModel('catalog/product');

$productCollection = Mage::getResourceModel('eav/entity_attribute_collection')

->setEntityTypeFilter($product->getResource()->getTypeId())
->addFieldToFilter('attribute_code', $attributeCode);

$attribute = $productCollection->getFirstItem()->setEntity($product->getResource());
print_r($attribute->getData()); // print out the available attributes
$options = $attribute->getSource()->getAllOptions(false);

print_r($options); // print out attribute options

The problem is it prints all the shoe sizes. I want only those which are "in stock"

Thank you in advance!

<?php
if ($_product->isConfigurable()&&$_product->isSaleable()) {
    $allProducts = $_product->getTypeInstance(true)->getUsedProducts(null, $_product);
    $sizeArray = array();
    foreach ($allProducts as $subproduct) {
        if ($subproduct->isSaleable()) {
            if($subproduct->getAttributeText('ATTRIBUTES')){
            $sizeArray[] = $subproduct->getAttributeText('ATTRIBUTES');
            }else{
            $sizeArray[] = $subproduct->getAttributeText('size_shorts_and_capris');
            }
        }
    }
    echo $this->__('Sizes: ');
    for ($x = count($sizeArray)-1; $x >= 0; $x--){
        echo $sizeArray[$x];
        if($x != 0)echo ', ';
    }
}
?>
