One more question if I may: I try to exclude global subnodes but so far unsuccessfully. Is it possible?
This correctly exports the corresponding node only:  items("SOMEGLOBAL(""ABC"",""XYZ"",""USERFORM_ATEST"").GBL") = ""
Now if I try to exclude this node from the SOMEGLOBAL like this,  items("SOMEGLOBAL.GBL",'"SOMEGLOBAL(""ABC"",""XYZ"",""USERFORM_ATEST"").GBL") = "", it does not exclude it. There is a barely visible single negating quote in the beginning of the second item.
