API Document Performance 中文 API 文档 更新文档

:house: A html parsing & node selecting and mutation library written in Rust, using APIs similar to jQuery, left off the parts thoes only worked in the browsers(e.g. render and event related methods).

It's not only helpful for the working with html scraping, but also have useful APIs to mutate text nodes, so you can use it for mixing your html with dirty html fragement, and keep the web scrapers away. :sparkling_heart:

use visdom::Vis;
use visdom::types::BoxDynError;

fn main() -> Result<(), BoxDynError>{
  let html = r##"
    <!DOCTYPE html>
    <html>
      <head>
        <meta charset="utf-8" />
      </head>
      <body>
        <nav id="header">
          <ul>
            <li>Hello,</li>
            <li>Vis</li>
            <li>Dom</li>
          </ul>
        </nav>
      </body>
    </html>
  "##;
  // load html
  let root = Vis::load(html)?;
  let lis = root.find("#header li");
  let lis_text = lis.text();
  println!("{}", lis_text);
  // will output "Hello,VisDom"
  Ok(())
