How to match a substring within 2 square brackets using RegEx in Rust

Answer 1

use regex::Regex;

fn extract_bracketed_content(text: &str) -> Vec<String> {
    let pattern = Regex::new(r"\[(.*?)\]").unwrap();
    
    pattern
        .captures_iter(text)
        .filter_map(|cap| cap.get(1).map(|m| m.as_str().to_string()))
        .collect()
}

fn main() {
    let input = "This is a [sample] string with [multiple] square brackets.";
    let extracted = extract_bracketed_content(input);

    for item in extracted {
        println!("{}", item);
    }
}
