How to make a word in a text modifiable(Change color, ....)

I have a problem, i have text stored in xml file formatting like this:


   
            
                    John
            
            
                    is
            
            
                    a doctor
            
   
   
            
                    He
            
            
                    has
            
            
                    a wife
            
   
    ....


I want to show this text for User(on a TextBox, a Panel,...) ,and tokens which have tag='man'(in this case:John,He ) have different color from the rest ,plus, they can be Clicked (to show extra information,etc) .It appears that in ToolBox there is not such a tool could do this .So I don't know how to solve it, does anybody have any suggestions ??Thanks for reading this!
