Use the arc:else keyword to execute an alternate block of code when a test like arc:exists or arc:match fails. You can also use it to execute an alternate block of code in an arc:call when the call fails to produce any output items. Unlike other languages, Script requires the arc:else statement to be within the scope of the test it belongs to.

      <arc:set attr="title" value="[filename]"/>
    </arc:else>
  </arc:null>
