Determine HL7 paths from the Variant

Does anyone have tcl code or guidance on how to determine the HL7 paths use by cloverleaf either from the standard or the customized file created under the message directory? ie 0(0).MSH or 2(0).1(0).0(0).OBR(0).#16(0)
2(0).1(0).0(0).OBR(0).#16(1)

Currently I use the output of the testing tool, but was wondering if someone hass a way to read below and provide accurate paths.

[ EVN ]

[{ DB1 } ]
[{ OBX } ]
[{ AL1 } ]
[{ DG1 } ]
[ DRG ]

{

[{ IN3 } ]
[ ZIN ]
