I have a tab structure like this 

page 1

--child 1.1

--child 1.2

----sub child 1.2.1

page 2

--child 2.1

--child 2.2

--

my client want it to display where if i am on a child it only displays the children of that page and just headers for the other pages - for examples

I am on child 1.1 the menu would look like

page 1

>>--child 1.1

--child 1.2

----sub child 1.2.1

page 2

I have tried a few dozen different ideas both with xslt and the node parameters but cant quite get what i need

Anyone have some pointers?
