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

Question

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


    <sentence>
            <token tag='man'>
                    John
            </token>
            <token>
                    is
            </token>
            <token>
                    a doctor
            </token>
    </sentence>
    <sentence>
            <token tag='man'>
                    He
            </token>
            <token>
                    has
            </token>
            <token>
                    a wife
            </token>
    </sentence>
    ....


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!
