Magento - >如何列出具有相同多重选择属性的产品?

I'm trying to retrieve products that carry same attribute. Specifically multiple select type. It seems the basic methods don't work. Selecting only the "name" attribute, I get all my products listed. When I try to filter "shop_by_color", it filters down, but not entirely. Not sure why it removes some and leaves others, even though they are the wrong ones. Any tips appreciated.

<?php 

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

$collection = $model->getCollection();
$collection->addAttributeToSelect('name');
$collection->addAttributeToFilter('shop_by_color'); // multiple select attribute
$collection->addFieldToFilter(array(array('attribute'=>'shop_by_color','finset'=>array('Yellow, White'),
)));

$collection->load();

?>

<ul>
<?php foreach($collection as $product) : ?>
<li><a href="<?php echo $product->getProductUrl() ?>"><?php echo $product->getName() ?></a></li>            
<?php endforeach; ?> 
</ul>

Hi I am not sure about your syntax I have never seen this sort of thing before.

<ul>
<?php foreach($collection as $product) : ?>
<li><a href="<?php echo $product->getProductUrl() ?>"><?php echo $product->getName()
 ?></a></li>            
<?php endforeach; ?> 
</ul>

Shouldn't it be...

<ul>
<?php foreach($collection as $product) { ?>
<li><a href="<?php echo $product->getProductUrl() ?>"><?php echo $product->getName()
 ?></a></li>            
<?php } ?> 
</ul>

<?php 
 $_productCollection=$this->getLoadedProductCollection();
 $_productCollection->clear()
->addAttributeToSelect('*')
->addAttributeToFilter('type_id', array('eq' => 'simple'))
->addAttributeToSort('name', 'ASC')
->addAttributeToSort('created_at', 'ASC')
->load();?>

on list page please use this type collection filter it's working fine.
