Okay so I want to be able to copy text from clipboard, I know words will always be the same at the start of the desired text I wish to extract from the clipboard, and I know what the end text will be. I want to extract this text and everything in-between it and save it in a history.

Can anyone give me tips or an example of how this might be done? I wan t to do this, if at all possible, using the tcl programing language, but I'm sure that if someone gives me an example say in python or something like this I could translate it over.

This is simple to do in C/C++

Just open a file, and in a while loop (while file is not eof) just use getline and set delimiters (eg the first and last line) in a if loop inside it just put contune, that (else) do something witht he rest of the data...

it's actually very easy.

file != clipboard

The easiest way to access the clipboard is probably by executing and reading output from an existing program that can do it, eg xclip. Else you would need to look at xlib or xcb bindings.

No its not, but the same princiles apply, open the data for reading and loop through it between 1 defined delimitor and another and in the process either map that data to something else or store it.
