Move XML once they're processed in Feeds
You can use hook_feeds_after_import to move xml after successful import.

/**
 * Invoked after a feed source has been imported.
 *
 * @param FeedsSource $source
 *  FeedsSource object that describes the source that has been imported.
 */
function hook_feeds_after_import(FeedsSource $source) {
  // See geotaxonomy module's implementation for an example.

  // We can also check for an exception in this hook. The exception should not
  // be thrown here, Feeds will handle it.
  if (isset($source-&gt;exception)) {
    watchdog('mymodule', 'An exception occurred during importing!', array(), WATCHDOG_ERROR);
    mymodule_panic_reaction($source);
  }else {

        // You can write here you own code to move xml.

   }
