simplify swmm network

[sangbosim]

Hello.
I am writing a code that modifies links that correspond to specific conditions for the purpose of simplifying the pipe network using the swmmio package.

The specific conditions are as follows:

1. Compare InletNode and OutletNode to see which Linkid exists only in InletNode.
2. Find out if Geom2 of XSECTION corresponding to Linkid 1 is less than 3.
3. If there is no value, exit, and if there is, change the link connection.

To do the above, what function should I use in swmmio?
Additionally, if you've ever written a code that simplifies the network, could you show me an example?

Thank you.
