Inside the for-each loop for Task i want to store the previous value of the node(taskEnd)
Please help me :(

You can't update a global variable in the way you are describing. I don't however see a Task for-each loop in your code above so can't really tell what you are trying to achieve.

If you show us what you are trying to output, and what your input looks like we can probably suggest a way of doing what you are trying to do in an XSLT manner.

I'm sorry, I don't have time to read all of that. Try distilling what you are trying to output to a few lines - this will often help you as much as it helps us.
