You should take a look at the Services module. Tutorials and examples for this module can be found in its Documentation.

Services is pretty heavy, for mobile apps I've used Views Bonus Pack's XML output format to create a view with exposed filters that returns results as XML: http://drupal.org/project/views_bonus
