Selecting a continuous set of lines / curves

Hi there, I’m working with surfaces, and i want to know if there is a way to select all the lines between the red one and the green.
(This is just a demonstration i work with way more lines that this)
All the lines are connected.
Let me know if you need further explanations of my problem.

If you don’t have split points where more than two lines connect to one point, you could just select all lines (of interest) and use Join. …or is there a need to keep the segments separate

SelChain could possibly do what you are after.

The thing is that i receive 3D files from others… And i have a lot of edges (the image is just a simplification) if a select a start line and a end line the program should have a command to join the lines between them. If i had only one edge and only one set of line it would be easy. I would do like you said.
