>> Suppose you've created a new Product Type "custom". I've posted how to add new product type in magento. You want to use a different template for those product. follow the instruction ::

  You can directly update in the catalog.xml or you can create a custom module by using Module Creator.

<layout>
  <PRODUCT_TYPE_custom>
    <reference name="product.info">
      <action method="setTemplate">

How to add custom product type in Magento

>> Basically You can't create a product type from Admin. You need to modify config.xml and sql in your module.

config.xml

<global>
    <catalog>
        <product>
            <type>
                <classified translate="label" module="vendor">
                    <label>Classified</label>
                    <model>vendor/product_type_classified</model>
                    <composite>0</composite>
                    <index_priority>50</index_priority>
                    <is_qty>1</is_qty>
                </classified>
            </type>
        </product>
    </catalog>
</global>

Here classified is my custom product type and vendor is my custom module.

Now you need to update price type attributes for new type : To run your sql file of your module for next time you need to delete the row created for the module "vendor" in core_resource table. We will discuss later for update Sql.
<?php

$installer = $this;
/* @var $installer Mage_Catalog_Model_Resource_Eav_Mysql4_Setup */

$installer->startSetup();

$setup = new Mage_Eav_Model_Entity_Setup('core_setup');

$fieldList = array(
    'price',
    'special_price',
    'special_from_date',
    'special_to_date',
    'minimal_price',
    'cost',
    'tier_price',
    'weight',
    'tax_class_id'
);

// make these attributes applicable to downloadable products
foreach ($fieldList as $field) {
    $applyTo = split(',', $setup->getAttribute('catalog_product', $field, 'apply_to'));
    if (!in_array('classified', $applyTo)) {
        $applyTo[] = 'classified';
        $setup->updateAttribute('catalog_product', $field, 'apply_to', join(',', $applyTo));
    }
}

$installer->endSetup();

?>

>> $prodAttributeSet = Mage::getModel('eav/entity_attribute_set')->load($_product->getAttributeSetId())->getAttributeSetName();


>> To get the attributeset name in cart page see the following..
app/design/frontend/base/default/template/checkout/cart/item/default.phtml (or in your theme folder.)

Here you can see the cart item object $_item = $this->getItem(); at line 28. Then you have to load the product with product id.
<?php
    $_product = Mage::getModel('catalog/product')->load($_item->getProductId());
    $prodAttributeSet = Mage::getModel('eav/entity_attribute_set')->load($_product->getAttributeSetId())->getAttributeSetName();
?>

How to get a html output through xml in Magento

>> Basically we use to get the content page like :

         <reference name="content">
            <block type="catalog/product_list" name="product_list" template="catalog/product/list.phtml" />
        </reference>

  It'll return html output with header, footer content. If you want to get only the content of list.phtml

        <block type="core/text_list" name="root" output="toHtml">
              <block type="catalog/product_list" name="product_list" template="catalog/product/list.phtml" />
        </block>




The above code will return only the content of list.phtml.
