Overriding Magento Sitemap Model Class

Question

I try to override Mage_Sitemap_Model_Resource_Catalog_Product class. Here is my files:

File \magento\app\etc\modules\Own_Sitemap.xml

    <?xml version="1.0" encoding="UTF-8"?>
    <config>
        <modules>
            <Own_Sitemap>
                <active>true</active>
                <codepool>local</codepool>
            </Own_Sitemap>
        </modules>
    </config>

File \magento\app\code\local\Own\Sitemap\etc\config.xml

    <?xml version="1.0"?>
    <config>
    <modules>
        <Own_Sitemap>
            <version>0.1</version>
        </Own_Sitemap>
    </modules>
    <global>
        <models>
            <sitemap>
                <catalog_resource>
                    <rewrite>
                        <product>Own_Sitemap_Model_Resource_Catalog_Product</product>
                    </rewrite>
                </catalog_resource>
            </sitemap>
        </models>
    </global>
    </config>

File \magento\app\code\local\Own\Sitemap\Model\Resource\Catalog\Product.php

class Own_Sitemap_Model_Resource_Catalog_Product extends Mage_Sitemap_Model_Resource_Catalog_Product
{
    /**
     * Get product collection array
     *
     * @param int $storeId
     * @return array
     */
    public function getCollection($storeId)
    {
        /* @var $store Mage_Core_Model_Store */
        $store = Mage::app()->getStore($storeId);
        if (!$store) {
            return false;
        }

        $this->_select = $this->_getWriteAdapter()->select()
            ->from(array('main_table' => $this->getMainTable()), array($this->getIdFieldName()))
            ->join(
                array('w' => $this->getTable('catalog/product_website')),
                'main_table.entity_id = w.product_id',
                array()
            )
            ->where('w.website_id=?', $store->getWebsiteId());

        $storeId = (int)$store->getId();

        /** @var $urlRewrite Mage_Catalog_Helper_Product_Url_Rewrite_Interface */
        $urlRewrite = $this->_factory->getProductUrlRewriteHelper();
        $urlRewrite->joinTableToSelect($this->_select, $storeId);

        $this->_addFilter($storeId, 'visibility',
            Mage::getSingleton('catalog/product_visibility')->getVisibleInSiteIds(), 'in'
        );
        $this->_addFilter($storeId, 'status',
            Mage::getSingleton('catalog/product_status')->getVisibleStatusIds(), 'in'
        );

        $entries = $this->_loadEntities();
        $this->_addFilter($storeId, 'inchoo_meta_robots', array(200, 201), 'in');
        $noindex = $this->_loadEntities();

        foreach ($entries as $k => $v){
            if (array_key_exists($k, $noindex)) {
                unset($entries[$k]);
            }
        }
        return $entries;
    }

}

When I try to generate new sitemap, application stiil use Mage class. I tried to remove the cache, but it did not help. What am I doing wrong?

Use below config instead of above to rewrite model

    #File \magento\app\code\local\Own\Sitemap\etc\congif.xml

    <?xml version="1.0"?>
    <config>
        <modules>
            <Own_Sitemap>
                <version>0.1</version>
            </Own_Sitemap>
        </modules>
        <global>
            <models>
                <sitemap>                    
                    <rewrite>
                        <resource_catalog_product>Own_Sitemap_Model_Resource_Catalog_Product</resource_catalog_product>
                    </rewrite>                   
                </sitemap>
            </models>
        </global>
    </config>

Replace your code in File \magento\app\etc\modules\Own_Sitemap.xml

From

<?xml version="1.0" encoding="UTF-8"?>
<config>
    <modules>
        <Own_Sitemap>
            <active>true</active>
            <codepool>local</codepool>
        </Own_Sitemap>
    </modules>
</config>

To

<?xml version="1.0"?>
<config>
    <modules>
        <Own_Sitemap>
            <active>true</active>
            <codePool>local</codePool>
        </Own_Sitemap>
    </modules>
</config>

Note: Magento will first take the node value (watch the upper case P in the node name).Then it is must be codePool

Replace your code in File \magento\app\code\local\Own\Sitemap\etc\config.xml

From

<?xml version="1.0"?>
<config>

                </catalog_resource>

 </config>

Above Answer is not working : correct configuration will be

<global>
  <models>    
    <sitemap_resource>
        <rewrite>
            <catalog_product>Own_Sitemap_Model_Resource_Catalog_Product</catalog_product>
        </rewrite>
    </sitemap_resource>
  </models>
</global>
