Pass parameters to Drupal to Return XML data Is there a module that allows the user to pass the parameters in POST or GET form, and Drupal will return in XML.

Like I have a view named table. table has fields named account_number and device_id. I would like to pass parameters in URL like

?view=table&amp;account_number=123&amp;device_id=d12

Then the Drupal would return in XML based on the searching criteria passed in URL.
Exposing Views as XML is one of the features of the Views Bonus Pack module.  You would lose your idea of using GET parameters, but you can easily build up other paths, pipe in your parameters, and get output as XML.

This is also something that the Services module can handle, but isn't as tightly coupled with views.  This module is very well documented, though.  In particular, I suggest reading the REST examples.  This is an add-on, Services Views, that may fit your needs, but I have never tried it.
