: Need help with merging two common tags of multi

Hi,

I am still stuck with this problem while trying to merge two common tags in
multiple xmls.
Every xml file has 4 sections:
1) systemInfo
2) systemInitialization
3) Procedure
4) systemWrapup

I have written rules for merging systemInfo systemInitialization and
systemWrapup sequentially. As they appear just once in my xmls there is no
problem. I am stuck with  Procedure tag as they may appear more than once
and I have to merge it sequentially by taking out from both the files and
modifying its attributes.

How can I achieve the output?
