How to remove string between two characters using regex

I have a string like below

{A:'XYZ'|B:‘123'}.[{C:‘pqr'}.{p:'a'}].{I1:'t123'|I2:'345'}

I want to remove all the characters between ' and ' and want a final result like

{A:|B:}.[{C:}.{p:}].{I1:|I2:}

I am using the regx like below

input.replaceAll("'.*?'", "");

But unable to get the desired result. Can someone point out what am I missing here ?

(?<=:).*?(?=[|}])

You can use lookarounds here.This way you dont need to worry about all the types of quotes and their combinations.See demo.

This basically removes everything from : to first | or }.This way you achieve what you want without caring about the contents between : and | or }

What you are doing : '.*?'

Let us see what is wrong. the symbol '.' should be used very carefully and only when needed. '.' in your case also consumes the chars which you don't what.

According to the patten, at first we can have a ‘ or '. So we can have (‘|') .Next we a looking for alphabets or numbers: [a-zA-Z1-9]* . In the end, same closing with ' . We have: 

('|‘)[a-zA-Z1-9]+'

Seems like your input contain accented single quote.

input.replaceAll("[‘'].*?'", "");
