HTML 反序列化

Hexilee 发表于

最近打算写的一个项目要处理大段 HTML,找了一下没啥比较方便的库,于是基于 scraperproc macro derive 写了个 HTML 的 deserializer,这里给个简短的 example

#[macro_use]
extern crate unhtml_derive;
extern crate unhtml;
use unhtml::{self, FromHtml};

#[derive(FromHtml)]
#[html(selector = "#test")]
struct SingleUser {
    #[html(selector = "p:nth-child(1)", attr = "inner")]
    name: String,

    #[html(selector = "p:nth-child(2)", attr = "inner")]
    age: u8,

    #[html(selector = "p:nth-child(3)", attr = "inner")]
    like_lemon: bool,
}

let user = SingleUser::from_html(r#"<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>Title</title>
</head>
<body>
    <div id="test">
        <div>
            <p>Hexilee</p>
            <p>20</p>
            <p>true</p>
        </div>
    </div>
</body>
</html>"#).unwrap();
assert_eq!("Hexilee", &user.name);
assert_eq!(20, user.age);
assert!(user.like_lemon);
