source ·Expand description
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 tree
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 lib

</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

let html = "<div id=cat />";
