Efficient tokens for rcdom::RcDom
Handle
parsing
aiming for O(1) HTML DOM walking.
This library aims to provide convenient and efficient handling of HTML DOM elements.
Examples
extern crate toks;
#[macro_use]
extern crate html5ever;
use toks::prelude::*;
use std::io::{self, Read};
pub struct LinkTok {
total: u32,
}
impl Tok for LinkTok {
fn is_match(&self, qn: &QualName) -> bool {
qn.local == local_name!("a")
}
fn process(&mut self, _: &mut Vec<Attribute>, _: &mut Vec<Handle>) {
self.total += 1;
}
}
// How to use
// $ cargo build --example count_links
// $ cat your.html | ./target/debug/examples/count_links
// Link <a> count 9
fn main() {
let mut chunk = String::new();
io::stdin().read_to_string(&mut chunk).unwrap();
let dom = parse_document(RcDom::default(), Default::default()).one(chunk);
let mut lt = LinkTok { total: 0 };
// Dropping mut reference
{
recursion(&mut vec![&mut lt], dom.document);
}
println!("Link <a> count {}", lt.total);
}
