How to find all double quote substrings in a string with Rust

Answer 1

use regex::Regex;

fn main() {
    let str_value = r#"This is a string with "double-quoted substring1", and "double-quoted substring2" inside."#;

    // Regular expression pattern to match substrings within double quotes
    let pattern = Regex::new(r#""([^"]*)""#).unwrap();

    // Find all matches
    let matches: Vec<String> = pattern
        .captures_iter(str_value)
        .map(|cap| cap[1].to_string())
        .collect();

    println!("{:?}", matches);
    
    for m in matches {
        println!("{}", &m); // Print each matched substring
    }
}

 
 
/*
run:
 
["double-quoted substring1", "double-quoted substring2"]
double-quoted substring1
double-quoted substring2

*/
