Uipath Selectors Selectors                         To identify an element on the UI tools require some kind of identification mechanism. This can be through background by element Id’s or UI Image. The unique way of identifying an element can be through its ID. User interfaces and HTML web pages are built using a series of containers, nested one inside the other. Selectors store these attributes, in the shape of an XML fragment so that a specific element from a window or page can be identified.                                                 For example lets consider text box element that is present in a container the element that has the ID as item1 and name on the element as Nokia, then the selector can look like            <webctrl Id='item1' aaname='Nokia' parentid='container1' tag='input'>                                                   Lets now see how to form selectors , in uipath we don’t need to struggle much to fo
