Html parser
A simple and general purpose html/xhtml parser lib/bin, using Pest.
Features
- Parse html & xhtml (not xml processing instructions)
- Parse html-documents
- Parse html-fragments
- Parse empty documents
- Parse with the same api for both documents and fragments
- Parse custom, non-standard, elements;
<cat/>,<Cat/>and<C4-t/> - Removes comments
- Removes dangling elements
- Iterate over all nodes in the dom three
What is it not
- It's not a high-performance browser-grade parser
- It's not suitable for html validation
- It's not a parser that includes element selection or dom manipulation
If your requirements matches any of the above, then you're most likely looking for one of the crates below:
Examples bin
Parse html file
html_parser index.html
Parse stdin with pretty output
curl <website> | html_parser -pExamples lib
Parse html document
use html_parser::Dom;
fn main() {
let html = r#"
<!doctype html>
<html lang="en">
<head>
<meta charset="utf-8">
<title>Html parser</title>
</head>
<body>
<h1 id="a" class="b c">Hello world</h1>
</h1> <!-- comments & dangling elements are ignored -->
</body>
</html>"#;
assert!(Dom::parse(html).is_ok());
}Parse html fragment
use html_parser::Dom;
fn main() {
let html = "<div id=cat />";
assert!(Dom::parse(html).is_ok());
}Print to json
use html_parser::{Dom, Result};
fn main() -> Result<()> {
let html = "<div id=cat />";
let json = Dom::parse(html)?.to_json_pretty()?;
println!("{}", json);
Ok(())
}
