I have transitioning from a primary Windows desktop environment to a Linux desktop, and found that I wanted to get my saved connections from superputty, which my co-workers are using to a Linux tool. I found a tool called PAC Manager which does what I needed.

The main thing I wanted was a tree hierarchy what the routers are split by location. SupperPutty uses an XML based config file and PAC Manager uses YAML files. The main problem was finding a way to discover and map out the tree structure, because SupperPutty list the hierarchy like a file listing with a separator of “/”.

I was able to use a Python to extract the XML elements, and create a list of directory tree objects and element objects. In PAC’s YaML you need to list each folder and element separately, you also need to show the parent child relationships in both the folder and they element. I have attached the current version of my Python code below. I may later develop this further into a library that abstracts and can import and export both formats fully, but the current code meets my current need.
