title: How to assign a null value in xml soapui
body: <p>I am creating a mock response using soapUI. In the response a certain element may or may not have a value (depending on the input sent by the user). I would like to assign this element a null value if the user has not sent anything to populate it with. I have tried using the <code>xsi:nil="true"</code> attribute but that ends up turning the whole value as null despite the user sending a value to populate it with. I have then tried <code>nillable="true"</code> but instead of assigning the value of null when the user hasn't sent anything, it assigns the value as empty strings; <code>""</code>. I would like to explicitly let it have the value of <code>null</code> if no user input has been given.</p>
