• field_ID - The name of the tree view field containing the node.
• node_index - An integer indicating the order the node appears in the field. The first node's index is 1, the second node's index is 2, and so forth. The index is based on a count of all nodes in the tree view field, regardless of whether the nodes are currently visible.
The node index is NOT related to the node ID assigned to individual nodes.
• node_label - The text label applied to the node. The label follows a comment symbol and is surrounded by single quotation marks.
• level - An integer indicating the node's hierarchical level, 1 for root-level nodes, 2 for their children, and so forth.
