Making a dynamic sequence(in Java)

Hey guys im having a problem trying to program out a set of logic. I want to make a Go(the board game) problem. What i want my program to do is read in an xml file that represents a series of steps a person can make to complete the puzzle, or a even a dead end. So in the xml it would look something like

<Step x="4" y="5">

    <Response x="4" y="6" />

    <Step x="3" y="6" victory="true">

    </Step>

</Step>

<!-- This is a dead end -->

<Step x="4" y="4">

    <Response x="4" y="5" />



    <Step x="5" y="5" defeat="true"></Step>

    <Step x="6" y="4" defeat="true"></Step>

</Step>

My thought is to make a link list of sorts where my xml handler(im using SAX) uses the step class to store a step inside a step, but i cant conceptualize how i would run down the list like that. Does anyone have a clean way of doing something like this? *Note i need to run down each and every step, and if the step doesnt exist, call them wrong and make them try again, but im willing to change my xml to whatever it needs to be.
