Struct scraper::element_ref::ElementRef
[−]
[src]
pub struct ElementRef<'a> { /* fields omitted */ }Wrapper around a reference to an element node.
This wrapper implements the Element trait from the selectors crate, which allows it to be
matched against CSS selectors.
Methods
impl<'a> ElementRef<'a>[src]
fn wrap(node: NodeRef<'a, Node>) -> Option<Self>
Wraps a NodeRef only if it references a Node::Element.
fn value(&self) -> &'a Element
Returns the Element referenced by self.
fn select<'b>(&self, selector: &'b Selector) -> Select<'a, 'b>
Returns an iterator over descendent elements matching a selector.
fn html(&self) -> String
Returns the HTML of this element.
fn inner_html(&self) -> String
Returns the inner HTML of this element.
fn text(&self) -> Text<'a>
Returns an iterator over descendent text nodes.
Methods from Deref<Target = NodeRef<'a, Node>>
fn value(&self) -> &'a T
Returns the value of this node.
fn id(&self) -> NodeId<T>
Returns the ID of this node.
fn parent(&self) -> Option<NodeRef<'a, T>>
Returns a reference to this node's parent.
fn prev_sibling(&self) -> Option<NodeRef<'a, T>>
Returns a reference to this node's previous sibling.
fn next_sibling(&self) -> Option<NodeRef<'a, T>>
Returns a reference to this node's next sibling.
fn first_child(&self) -> Option<NodeRef<'a, T>>
Returns a reference to this node's first child.
fn last_child(&self) -> Option<NodeRef<'a, T>>
Returns a reference to this node's last child.
fn has_siblings(&self) -> bool
Returns true if this node has siblings.
fn has_children(&self) -> bool
Returns true if this node has children.
fn ancestors(&self) -> Ancestors<'a, T>
Returns an iterator over this node's ancestors.
fn prev_siblings(&self) -> PrevSiblings<'a, T>
Returns an iterator over this node's previous siblings.
fn next_siblings(&self) -> NextSiblings<'a, T>
Returns an iterator over this node's next siblings.
fn children(&self) -> Children<'a, T>
Returns an iterator over this node's children.
fn first_children(&self) -> FirstChildren<'a, T>
Returns an iterator over this node's first children.
fn last_children(&self) -> LastChildren<'a, T>
Returns an iterator over this node's last children.
fn traverse(&self) -> Traverse<'a, T>
Returns an iterator which traverses the subtree starting at this node.
