Vivvo CMS supports XML output for all modules (such as box_article_list module), however this option is not enabled by default.
To enable XML output, you need to register the module first:
INSERT INTO `configuration` ( `id` , `variable_name` , `variable_property` , `variable_value` , `module` , `domain_id` , `reg_exp` ) VALUES ( NULL , 'xml', 'content_handler_function', 'xml_content_handler', 'url_modules', '1', NULL ), ( NULL , 'xml', 'url_handler_function', 'xml_url_handler', 'url_modules', '1', NULL ), ( NULL , 'xml', 'file', 'lib/vivvo/url_handlers/xml.php', 'url_modules', '1', NULL );

where search_cid is category ID for which the articles are outputted.
