XCART-5 Get Attributes Values in programming and Assigning some other values progmatically

I am working on Xcart-5 website customization. And I created my own module and doing work on that. I just created some Global Attributes (" As a Plain text ") field and assign these attributes to some product. Now I want to access these fields value in programming in the product details page for assigning some other value programatically at run time.

How can I achieve this task. Kindly provide me the solution .

In your module you should decorate the \XLite\Model\Attribute class and extend the getAttributeValue() method there.

For instance, if I use a module with developer ID Tony and module ID AttributesDemo, then I would need to create the XCartDirectory/classes/XLite/Module/Tony/AttributesDemo/Model/Attribute.php file with the following content:

<?php
// vim: set ts=4 sw=4 sts=4 et:

namespace XLite\Module\Tony\AttributesDemo\Model;

/**
 * Attribute
 * @MappedSuperClass
 */
abstract class Attribute extends \XLite\Model\AttributeAbstract implements \XLite\Base\IDecorator
{
    public function getAttributeValue(\XLite\Model\Product $product, $asString = false)
    {
        $result = parent::getAttributeValue($product, $asString);

        if (!$asString) {
            foreach ($result as $obj) {
                if ($obj->asString() == 'Mac') {
                    $obj->getAttributeOption()->setName('Windows');
                }
            }
        }

        return $result;
    }
}

Such implementation will change Mac values to Windows ones in all attributes.
