Hi Yurii,

the PathMapper is a very complicated piece of work, thousands of lines of code go into evaluating and parsing the mapping masks. You can however use PathMapper logic from your own code. What you need to do is create a GH_LexerCombo which contains the source and target mappings. Then you can call GH_Lexer.PerformLexicalReplace() to map a data tree.

Hi David,

Thank you great for answer. I want to split the sheet just as does Path Mapper on picture. It is Necessary therefor that to understand as they are bound indexes and paths. That it is necessary to change in this code to has occurred partition? GH_Lexer.PerformLexicalReplace() - much incomprehensibly for me although I have GH SDK, this it is difficult. I was more simply use List and DataTree parameters. Possible this do? With best wishes.

Here is code

Dim tree As New DataTree(Of String)
Dim i,j As Integer
Dim iList As New List (Of System.Object)
For i = 0 To nIndex
iList.Add(x(i))
Next
For j = 0 To nPaths - 1
Dim path As New GH_Path(j)
tree.Add(x(j), path)
Next
A = tree
B = iList
