Custom field in XML with Views RSS module I need to create an XML using Views RSS module, and it's created correctly. But I want to add a custom field to the XML. For example, an item from the XML is:

&lt;item&gt; 
&lt;title&gt;Liburu bat&lt;/title&gt;
 &lt;link&gt;http://whatever.com/comercios/productos/1022/botak&lt;/link&gt;
 &lt;description&gt;Produktu bat&lt;/description&gt;
 &lt;category&gt;Forros para botas %% Espuelas %% Calzado&lt;/category&gt;
 &lt;guid isPermaLink="false"&gt;1022&lt;/guid&gt;
 &lt;source url="http://whatever.com/es/comercios/productos/whatever.xml"&gt;Escaparate Whatever&lt;/source&gt;
&lt;/item&gt;


And I want to add a custom field to that item, for example: 
Something else 

Any idea how can I do it?
You need to implement a hook_views_rss_item_elements() invocation if you're wanting to add a custom item element. For example:

/**
 * Implements hook_views_rss_item_elements().
 */
function MYMODULE_views_rss_item_elements() {
  $elements['my_element'] = array(
    'title' =&gt; t('My Element'),
    'description' =&gt; t('Provides a my_element to an item element in Views RSS.'),
  );
  return $elements;
}
