function hook_juicebox_xml_class_alter in Juicebox HTML5 Responsive Image Galleries 7.2

Allow modules to alter the class used for a Juicebox XML loader.

Any Drupal formatter that creates Juicebox embed code must also provide a way for the associated Juicebox XML to be generated. This is typically handled via a seperate request that can be routed and managed any way you like (such as a dedicated Drupal menu item). If you want to use the existing "juicebox/xml/%" menu item for this, you can specifiy a custom XML loader class (implementing JuiceboxXmlInterface) and then "register" it with this hook.

Parameters

string $xml_loader_class: The Juicebox XML loader class that should be instantiated given the passed URL args.

array $args: The args that appear after /juicebox/xml in the path.
