ignoring certain characters with regex
I'm reading a text file where I'm adding words to a data structure and I have the following line.
- 'tis the season to read the Qu'ran
I'm trying to use regex to delete the apostrophe from the tis but I want to keep it where it says Quran. I basically want the regex expression to ignore the apostrophe if it is between characters.
I have something like but I'm pretty new to Regex. Any ideas on what I should do or what parts of regex I should look at.
('w)|(w+'w+)
it highlights the words only with apostrophes but I can't seem to figure out how to "negate" the second expression.

Here is a regex which will target apostrophe only if it does not fall in between two characters:
(?<=s|^)'(?=w)|(?<=w)'(?=s|$)
