How do I get "href" value of an "a" tag using scaper in Rust?

Question

I have a Rust project that used the "scraper" library. I want to get the href value of an a tag element from a website. It is not shown in the documentation how to do it. I tried the below code but it only returned the inner HTML content.

let result_sites: scraper::Selector =
        scraper::Selector::parse("a.s-topbar--logo").unwrap();

What is the best way to get the href value?

Answer 1

use scraper::{Html, Selector};

let html = r#"..."#;
let fragment = Html::parse_fragment(html);
let sites_selector = Selector::parse("a.s-topbar--logo").unwrap();

for el in fragment.select(&sites_selector) {
    let href = el.value().attr("href").unwrap();
    println!("{:?}", href);
}

Here is the documentation with example
