Struct lol_html::html_content::Doctype

pub struct Doctype<'i> { /* private fields */ }

Expand description

A document type declaration preamble.

Note that unlike other HTML content, Doctype can’t be modified and should be used only for the examination purposes.

§Example

use lol_html::{rewrite_str, doctype, RewriteStrSettings};

rewrite_str(
    r#"<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "DTD/xhtml1-transitional.dtd""#,
    RewriteStrSettings {
        document_content_handlers: vec![
            doctype!(|d| {
                assert_eq!(d.name(), Some("html".into()));
                assert_eq!(d.public_id(), Some("-//W3C//DTD XHTML 1.0 Transitional//EN".into()));
                assert_eq!(d.system_id(), Some("DTD/xhtml1-transitional.dtd".into()));

                Ok(())
            })
        ],
        ..RewriteStrSettings::default()
    }
).unwrap();
