How to convert multiple <br/> tags to a single <br/> tag using RegEx in C++

Answer 1

#include <iostream>
#include <regex>
#include <string>

int main() {
    std::string input = "ab<br/><br/>cd<br/>efg<br/><br/><br/>hijk<br/><br/>";

    // Regex to match multiple consecutive <br/> tags
    std::regex br_regex("(<br\\s*/?>\\s*)+");

    // Replace with a single <br/>
    std::string output = std::regex_replace(input, br_regex, "<br/>");

    std::cout << output << std::endl;
}

 
 
/*
run:

ab<br/>cd<br/>efg<br/>hijk<br/>
 
*/
