How to get the next value of element in context node

$

Hello,

I have a context node and on a form we are displaying it's attribute value. We made one attribute as link to action so when user click on that a new popup window will be shown with the value selected. On this pop up we have 2 buttons Next and Previous. When user click on Next without closing the pop up window it should display the next value of that node on the same attribute. How Can I achieve this ? I think I can iterate through all the values and can get the elementsat(i+1) but is there any other way through which I can directly get the next element attributes.

 

or How Can I get the next and previous values of elements in a context node.

 

Regards,

MS
