This document shows an example about the access to the data stored in the customlib tree. We are using the cmas2d_customlib tree as example.
The customlib tree is stored in a xml document. To manage an xml object, we use the tdom functions, available in https://docs.activestate.com/activetcl/8.6/tcl/tdom
To get the value of the weight applied to the group Point Weight Auto1, we need to define the xpath to the value, and ask it to the document.
