The following comments refer to the nodeIdOrIndexSeries parameter.
When building nodes, WinStudio assigns a unique ID to each node.
This is its GUID. A node’s GUID value can be obtained through various
APIs, returning an XML document string. GUID string values can be
used to explicitly identify tree nodes.
Assume you have these tree nodes:
Each node can also be represented by a node index series (comma-separated
numeric values to indicate the node index at each level).
For example, for node "XYZ" in the above tree, found at
Level 2, Index 0, the node index series is 2,0 (index 2 at
Level 0; index 0 at Level 1).
