hotmeal 2.0.3

HTML toolkit with arena-based DOM, html5ever parsing, and serialization
Documentation
//! HTML toolkit based on html5ever and cinereus.
//!
//! hotmeal provides:
//! - **Arena-based DOM**: Efficient arena-allocated tree with zero-copy parsing
//! - **Parsing**: Browser-compatible HTML5 parsing via html5ever with full error recovery
//! - **Serialization**: HTML5-correct serialization with proper escaping
//! - **Diffing**: DOM patch generation for live-reloading
//!
//! # Example
//!
//! ```rust
//! use hotmeal::{parse, NodeKind, StrTendril};
//!
//! let input = StrTendril::from("<!DOCTYPE html><html><body><p>Hello!</p></body></html>");
//! let doc = parse(&input);
//! assert_eq!(doc.doctype.as_ref().map(|s| s.as_ref()), Some("html"));
//!
//! if let Some(body_id) = doc.body() {
//!     for child_id in body_id.children(&doc.arena) {
//!         let node = doc.get(child_id);
//!         if let NodeKind::Element(elem) = &node.kind {
//!             println!("Found {} element", elem.tag);
//!         }
//!     }
//! }
//!
//! // Serialize back to HTML
//! let html = doc.to_html();
//! ```
