I think you would have to make a script, python or tcl, to generate a outputschema based on the attribute u want to order.
That would involve a workspacerunner probably.
Hi,
Do you perhaps need to swap multiple attribute values by ascending order like this?
Input attribute name : value
FieldA : 3
FieldB : 1
FieldC : 2
Output attribute name : value
FieldA : 1
FieldB : 2
FieldC : 3
If so, one possible way is to use a list attribute.
1) Convert target attributes to a list attribute (AttributeRenamer).
FieldA --> _list{0}
FieldB --> _list{1}
FieldC --> _list{2}
2) Sort the list elements (ListSorter).
3) Recover the original attribute names (AttributeRenamer)
_list{0} --> FieldA
_list{1} --> FieldB
_list{2} --> FieldC
