Replace extraspaces of a string after pattern matching using rwcrexpr in C++

Question

I have a string like below

std::string = "S.ID="1234" S.NAME="Sachin"    S.NICKNAME="God  of  cricket" S.CITY="MUMBAI";

I need to replace each extra spaces after the pattern ="*" with a single space using RWCRexpr

Any help on this?

Answer 1

The regular expression \\s*=\\s*"\\[^\\"\\]*"(\\s{2,}) will match your extra spaces.

Hovewer, according to the online documentation, RWCRexpr is deprecated and your should use RWTRegex<T> instead.
