Html

Struct Html

pub struct Html {
    pub errors: Vec<Cow<'static, str>>,
    pub quirks_mode: QuirksMode,
    pub tree: Tree<Node>,
}

Expand description

An HTML tree.

Parsing does not fail hard. Instead, the quirks_mode is set and errors are added to the errors field. The tree will still be populated as best as possible.

Implements the TreeSink trait from the html5ever crate, which allows HTML to be parsed.

Fields§

§errors: Vec<Cow<'static, str>>

Parse errors.

§quirks_mode: QuirksMode

The quirks mode.

§tree: Tree<Node>

The node tree.

Implementations§

impl Html

pub fn new_document() -> Html

Creates an empty HTML document.

pub fn new_fragment() -> Html

Creates an empty HTML fragment.

pub fn parse_document(document: &str) -> Html

Parses a string of HTML as a document.

This is a convenience method for the following:

use html5ever::driver::{self, ParseOpts};
use scraper::{Html, HtmlTreeSink};
use tendril::TendrilSink;

let parser = driver::parse_document(HtmlTreeSink::new(Html::new_document()), ParseOpts::default());
let html = parser.one(document);

pub fn parse_fragment(fragment: &str) -> Html

Parses a string of HTML as a fragment.

pub fn select<'a, 'b>(&'a self, selector: &'b Selector) -> Select<'a, 'b>

Returns an iterator over elements matching a selector.

pub fn root_element(&self) -> ElementRef<'_>

Returns the root <html> element.

pub fn html(&self) -> String

Serialize entire document into HTML.

Trait Implementations§

impl Clone for Html

fn clone(&self) -> Html

Returns a duplicate of the value. Read more

1.0.0§

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source. Read more

impl Debug for Html

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

impl PartialEq for Html

fn eq(&self, other: &Html) -> bool

Tests for self and other values to be equal, and is used by ==.

1.0.0§

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl<'a> Selectable<'a> for &'a Html

type Select<'b> = Select<'a, 'b>

Iterator over element references matching a [CSS selectorSelector

fn select(self, selector: &Selector) -> <&'a Html as Selectable<'a>>::Select<'_>

Applies the given selector to the collection of elements represented by self

impl Serialize for Html

fn serialize<S>( &self, serializer: &mut S, traversal_scope: TraversalScope, ) -> Result<(), Error>
where S: Serializer,

Take the serializer and call its methods to serialize this type. The type will dictate which methods are called and with what parameters.
