Node help!

I have some element data in excel which i am importing in to revit using dynamo. Then, I use that data to create a new element in revit for some checks. But, at last after using it, add a comment for each item based on the check and export as into excel as well as delete the element from the revit file simultaneously. How can this be done? Any ideas?

It is so big. I thought it is much easier this way. It is a small part. Anyway, I will share the work in the drive link. Here it is. Kindly help.

Sorry, I will give a little explanation. I want to place each new trestle from excel at a particular point in Revit and see for clash detection and finally export into an excel sheet with an extra comment to each trestle whether it is clashing or not. I want to automate it within a single click. I hope that is sufficient to make you understand the problem.
