XML Structure Tab: Eliminate Duplicates Column

Applies to: Marshalling data to XML only

Available: For mapped nodes only. When you have placed a checkmark in the "Combined Node" column for an element, for each element that shows a combined status, either directly set or inherited.

	Duplicate occurrences of children of this node will be eliminated from the results of the marshal operation.

Explanation

Summary | Examples

When Eliminate Duplicates is set on a node, the engine examines the entire child structure of the node on which it is set. It compares the tag, node name, attributes, sub-nodes and the whole subtree. As soon as a mismatch is found, the node is discarded. If no mismatch is found, a duplicate node is removed from the XML output.
