This one of the 4 options, that you can set for fragment processing in Spool2XML.The value selected affects the output XML file generated from the standard XML spooled file.

With the value 3=Treebuilder the output XML file can be created as the most compact output XML file:

1.The fragment option on record formats is ignored. The key-field option (value X) is ignored. A fragment/Tree record format and Tree key is defined by setting a field to be T=Top.

2.Only record formats, that are related (as either parent or child) to the Top-tree record format are included in the final XML file.

3.Children, that are listed prior to the first occurrence of the Top-record format are not included in the final output.

4.Children are always matched with the previous parent(s). The last found parent in the spooled file will be used.

5.Top nodes/record formats are only included as one for each unique value of the Top-key field.

6.The key options D=Delete and T=Top are only supported for 3=Treebuilder. Use D=Delete to delete a field from the output XML file.

7.The parent/child option on record formats: 1=Single child is only supported for 3=Treeebuilder, which will cause an extra set of parents for each instance of the child - to keep it a single child.
