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§
Source§impl Html
impl Html
Sourcepub fn new_document() -> Self
pub fn new_document() -> Self
Creates an empty HTML document.
Sourcepub fn new_fragment() -> Self
pub fn new_fragment() -> Self
Creates an empty HTML fragment.
Sourcepub fn parse_document(document: &str) -> Self
pub fn parse_document(document: &str) -> Self
Parses a string of HTML as a document.
This is a convenience method for the following:
use html5ever::driver::{self, ParseOpts};
use 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) -> Self
pub fn parse_fragment(fragment: &str) -> Self
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.

&self,
serializer: &mut S,
traversal_scope: TraversalScope,
) -> Result<(), Error>
fn serialize<S: Serializer>( &self, serializer: &mut S, traversal_scope: TraversalScope, ) -> Result<(), Error>
Take the serializer and call its methods to serialize this type. The type will dictate
which methods are called and with what parameters.

Note: does not support the <template>
element.

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 set_quirks_mode(&mut self, mode: QuirksMode)
Set the document’s quirks mode.
Source§fn get_document(&mut self) -> Self::Handle

Get a handle to the
Document
node.Source§fn same_node(&self, x: &Self::Handle, y: &Self::Handle) -> bool
fn same_node(&self, x: &Self::Handle, y: &Self::Handle) -> bool
Do two handles refer to the same node?
Source§fn elem_name(&self, target: &Self::Handle) -> ExpandedName<'_>
fn elem_name(&self, target: &Self::Handle) -> ExpandedName<'_>
What is the name of this element? Read more
Source§fn create_element(
&mut self,
name: QualName,
attrs: Vec<Attribute>,
_flags: ElementFlags,
) -> Self::Handle
fn create_element( &mut self, name: QualName, attrs: Vec<Attribute>, _flags: ElementFlags, ) -> Self::Handle
Create an element. Read more
Source§fn create_comment(&mut self, text: StrTendril) -> Self::Handle

)
fn append_doctype_to_document( &mut self, name: StrTendril, public_id: StrTendril, system_id: StrTendril, )
Append a
DOCTYPE
element to the Document
node.Source§fn append(&mut self, parent: &Self::Handle, child: NodeOrText<Self::Handle>)
fn append(&mut self, parent: &Self::Handle, child: NodeOrText<Self::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
Source§fn append_before_sibling(
&mut self,
sibling: &Self::Handle,
new_node: NodeOrText<Self::Handle>,
)
fn append_before_sibling( &mut self, sibling: &Self::Handle, new_node: NodeOrText<Self::Handle>, )
Append a node as the sibling immediately before the given node. Read more
Source§fn remove_from_parent(&mut self, target: &Self::Handle)
fn remove_from_parent(&mut self, target: &Self::Handle)

Source§fn reparent_children(&mut self, node: &Self::Handle, new_parent: &Self::Handle)
fn reparent_children(&mut self, node: &Self::Handle, new_parent: &Self::Handle)

fn add_attrs_if_missing(&mut self, target: &Self::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.
Source§fn get_template_contents(&mut self, target: &Self::Handle) -> Self::Handle
fn get_template_contents(&mut self, target: &Self::Handle) -> Self::Handle
Get a handle to a template’s template contents. The tree builder

fn append_based_on_parent_node( &mut self, element: &Self::Handle, prev_element: &Self::Handle, child: NodeOrText<Self::Handle>, )
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.
