See the COPYRIGHT file in the top-level directory of this distribution and at https://raw.githubusercontent.com/lemonrock/html5ever_ext/master/COPYRIGHT. #![warn(missing_docs)] //! # html5_ext //! //! This is a set of unofficial extensions to the [html5ever](https://github.com/servo/html5ever) crate's RcDom and Node structs, including a ***minifying HTML5 serializer*** and support for ***CSS matching**. //! //! It re-exports the `css` and `html5ever` crates, and useful DOM types hidden inside the `::html5ever::markup5ever::rcdom` module. //! //! //! ## How Tos //! //! //! ### To load and minify HTML5 //! //! ``` //! extern crate html5_ext; //! use ::html5ever_ext::RcDom; //! use ::html5ever_ext::RcDomExt; //! use ::html5ever_ext::Minify; //! //! let rc_dom = RcDom::from_file_path_verified_and_stripped_of_comments_and_processing_instructions_and_with_a_sane_doc_type("/path/to/document.html").expect("invalid HTML"); //! rc_dom.minify_to_file_path(); //! ``` //! //! There are additional methods available on `Minify` to minify to a byte array or a generic `Write`-implementing writer. //! //! For more control, eg over serializing multiple node graphs, use the struct `UltraMinifyingHtmlSerializer` directly. //! //! //! ### To match CSS selectors //! //! ``` //! extern crate html5_ext; //! use ::html5ever_ext::RcDom; //! use ::html5ever_ext::RcDomExt; //! use ::html5ever_ext::parse_css_selector; //! use ::html5ever_ext::Selectable; //! use ::html5ever_ext::Minify; //! //! let rc_dom = RcDom::from_file_path_verified_and_stripped_of_comments_and_processing_instructions_and_with_a_sane_doc_type("/path/to/document.html").expect("invalid HTML"); //! //! let selector = parse_css_selector("p.myclass").unwrap(); //! //! assert!(!rc_dom.matches(&selector)); //! //! rc_dom.find_all_matching_child_nodes_depth_first_including_this_one(&selector, |node| //! { //! //Minify is implemented on node.children as well as node and rc_dom. //! eprintln!("{}", node.children.debug_string()); //! //! const SHORTCUT: bool = false; //! SHORTCUT //! }) //! ``` //! //! ### To work with Nodes //! //!
