How to match a string of the form 'word=A B|word=C|word=D E word=E|word=F G'?

Question

I am trying to match strings of the form word=A B|word=C|word=D E word=F|word=G H using Python's re module. The string is in one line. This is the output that I want:

word=A B|word=C|word=D E , word=F|word=G H

This is my regex till now

word=(?:[^word]\w+\s*\w+(\|?:=[^word]*)?)

It's an incomplete regex for now, and I have been trying to improve upon it with no desirable output.

Answer 1

If you want to match the entire string, use below regex

(?:word=[\w |]+(?=word|$))+

Demo

If you want to just place comma, considering | as delimiter use below regex, with re.sub().

\s(?=word=)

Example

import re
text="word=A B|word=C|word=D E word=F|word=G H"
print(re.sub(r"\s(?=word=)",",",text))

Output

word=A B|word=C|word=D E,word=F|word=G H
