My xml contains the reords of an employee shift and it's task. so it might be possible that one employee in one has to do many task. so my xml contains the reords as:

The problem is that as i have to show this on a chart then there it shows as


but i wan't to show it like
72 Biswal, Antje shiftstarttime shiftendtime task1 task2

 m able to show it like that one problem is there i wan't to compare the current TaskStart to the previous TaskStart.
How m able to do that???

Have you tried the links to grouping given in the first post in this forum?

yup, but m not able to do that.
Help me


Thanx for ur reply.

You're grouping stuff looks fine - but you say you need to compare the current TaskStart to the 'previous' one.

Have you tried "preceding-sibling::Detail[1]/TaskStart"?

actually what i want to show the xml data to the browser in the form of a chart where i want to depict the employee shifts and their tasks.
it look like as:
                                              scale used to show task according to time
shift shiftname empName ShiftStart ShiftEnd -------------------------------------------------------------------------
                                            00:00 01:00 02:00 03:00-------------------------23:00
                                            --------------------------------------------------------------------------
72 F11 Biswal, Antje 2:30 11:00 Task1 task2

so what i done is at time of task firstly a yellow line comes which is calculated on the basis of Shift start and end and then draw a yellow <td>
there and then in that i make another table which is used to show task. m able to show the first task and it shows accurately but in second task i have to find the gap between first task and second so can i get the previous values to find the Task.

Does my previous suggestion provide you access to the previous task start element? If so then you just have a load of calculations to work out - something I think you're going to have to do yourself.
