A software robot is configured to automatically identify a target element (e.g., a button, a form field, etc.) within a user interface (UI) according to a set of attributes of the target element specified in the source-code of the respective UI. The robot's code specification includes a multiplicity flag which, when set, causes the robot to search for the target element within multiple instances of a UI object matching a subset of the set attributes (for instance, within all windows having a specific name, within all browser tabs, etc.)
