Struct Pattern

pub struct Pattern(/* private fields */);

Expand description

Pattern for matching HTML document

§Example

use easy_scraper::Pattern;

let pat = Pattern::new(r#"
<ul>
    <li>{{hoge}}</li>
</ul>
"#).unwrap();

let ms = pat.matches(r#"
<!DOCTYPE html>
<html lang="en">
    <body>
        <ul>
            <li>1</li>
            <li>2</li>
            <li>3</li>
        </ul>
    </body>
</html>
"#);

assert_eq!(ms.len(), 3);
assert_eq!(ms[0]["hoge"], "1");
assert_eq!(ms[1]["hoge"], "2");
assert_eq!(ms[2]["hoge"], "3");
