How to search and extract part of string in batch script?

Question

I am pretty new to windows batch scripting and am having trouble to search and extract a portion of a string from a text file and display it out. Some samples data are shown below.

The keyword for searching is based on student ID, for example: STUD777012

Appreciate if you could help out.

Thank you very much.

If you open the file in Notepad++ and do a regex replace (Ctrl+H):

Find what: Compiling (\w+).*?(return code[^\r\n]*).*?(analysis detected.*?)(\n|$)
Replace with: \1 \2 \3

You should get what you want. Make sure you have regex enabled and '. matches new line' set. e.g.
