pub struct Html {
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 fast_html5ever crate, which allows HTML to be parsed.
Fields§
§quirks_mode: QuirksModeThe quirks mode.
tree: Tree<Node>The node tree.
Implementations§
Source§impl Html
impl Html
Sourcepub fn new_document() -> Html
pub fn new_document() -> Html
Creates an empty HTML document.
Sourcepub fn new_fragment() -> Html
pub fn new_fragment() -> Html
Creates an empty HTML fragment.
Sourcepub fn parse_document(document: &str) -> Html
pub fn parse_document(document: &str) -> Html
Parses a string of HTML as a document.
This is a convenience method for the following:

use accessibility_scraper::Html;
use tendril::TendrilSink;
let parser = driver::parse_document(Html::new_document(), ParseOpts::default());
let html = parser.one(document);Sourcepub fn parse_fragment(fragment: &str) -> Html
pub fn parse_fragment(fragment: &str) -> Html
Parses a string of HTML as a fragment.
Sourcepub fn select<'a, 'b>(&'a self, selector: &'b Selector) -> Select<'a, 'b>
pub fn select<'a, 'b>(&'a self, selector: &'b Selector) -> Select<'a, 'b>
Returns an iterator over elements matching a selector.
Sourcepub fn root_element(&self) -> ElementRef<'_>
pub fn root_element(&self) -> ElementRef<'_>
Returns the root <html> element.

Note: does not support the <template> element.
Source§type Handle = NodeId
type Handle = NodeId
Handle is a reference to a DOM node. The tree builder requires
that a Handle implements Clone to get another reference to
the same node.Source§fn parse_error(&mut self, msg: Cow<'static, str>)
fn parse_error(&mut self, msg: Cow<'static, str>)
Signal a parse error.
Source§fn set_quirks_mode(&mut self, mode: QuirksMode)

fn append_doctype_to_document( &mut self, name: Tendril<UTF8>, public_id: Tendril<UTF8>, system_id: Tendril<UTF8>, )
Append a
DOCTYPE element to the Document node.Source§fn append(

parent: &<Html as TreeSink>::Handle,
child: NodeOrText<<Html as TreeSink>::Handle>,
)
fn append( &mut self, parent: &<Html as TreeSink>::Handle, child: NodeOrText<<Html as TreeSink>::Handle>, )
Append a node as the last child of the given node. If this would
produce adjacent sibling text nodes, it should concatenate the text
instead. Read more

)
fn add_attrs_if_missing( &mut self, target: &<Html as TreeSink>::Handle, attrs: Vec<Attribute>, )
Add each attribute to the given element, if no attribute with that name
already exists. The tree builder promises this will never be called
with something else than an element.

When the insertion point is decided by the existence of a parent node of the
element, we consider both possibilities and send the element which will be used
if a parent node exists, along with the element to be used if there isn’t one.

fn pop(&mut self, _node: &Self::Handle)
Indicate that a node was popped off the stack of open elements.
