[Closed] redefine CAs and Handlers inside Attribute Holder ??

i still wondering if anyone can help me to implement my script to extract the connections and expressions between defs…

at now,
only work if i specify the slave node connection, eg:

obj.pos.controller[2].controller (child wire of CA.test.fk)

i wish i could do the oposite…
picking the main def inside modifier CA, force my script to search who is the child connection, what is it sub anim and track controller, the string of expression…

thanks for any help
