getElementsByTagName() always return an array. You need to determine the array size instead of checking the key exists or not.

Code:
         my @node_list = $action->getElementsByTagName('Action-category');

         if (@node_list > 0)
         {
            print "Action-category defined\n";
         }
         else
         {
            print "Action-category NOT defined\n";
         }

dtactionicon

DtActionIcon(library call)												DtActionIcon(library call)

NAME

       DtActionIcon -- get the icon information for an action

SYNOPSIS

       #include <Dt/Action.h>
       char *DtActionIcon(
       char *actionName);

DESCRIPTION

       The  DtActionIcon  function  gets  the  icon  information  for an action.  The actionName argument is the name of the action.  DtActionIcon
       returns the name of the icon associated with an actionName action.  If the action definition does not explicitly  identify  an  icon  name,
       this  function  returns the default action icon name, as described in dtactionfile(4) (``Action Selection'').  The default action icon name
       can be customized using the actionIcon X resource.

       If there are multiple actionName actions, the string returned is the icon associated with the most general action.  The most general action
       is the one with the lowest precedence, as described in dtactionfile(4) (``Action Selection'').

RETURN VALUE

       Upon  successful completion, the DtActionIcon function returns a newly allocated copy of the icon name string ( ICON field) associated with
       the action; otherwise, it returns NULL.

APPLICATION USAGE

       The DtActionIcon function is useful for applications that provide a graphical interface to actions.

       The application should use XtFree(3) to free the icon name string returned by the DtActionIcon function.

SEE ALSO

       Dt/Action.h - DtAction(5), XtFree(3) dtactionfile(4), dtdtfile(4).
