How could I create a txt or rtf list of all groups and sub-groups names and item links?

DEVONthink

I created a new version as per your instructions. Links are added which is perfect

My remaining problem is that the result is a huge list which is a dizzying mishmash of name + links of trash, tags, groups, subgroups and docs.

Would you have the patience to show me how to modify the script so that I end up with a listing of only Groups and SubGroups including names and Links. If possible, subgoups start with a tab under the group name.
I don’t want to include listing of tabs, documents and if possible no trash.

Thanks very much
