Hi,

I have a data display in the screen in the following format

package1/subpackage1/file1,file2
package2/subpackage2/file3,file4
.
.
packagen/…

i can add new package/sub package and so on…

is there any way where i can collect all changed data in all the nodes?

my requirement is to collect all changed/added data on any action by the page.

Any help will be highly appreciated.

thanks
