func MustCompile

func MustCompile(sel string) Selector

MustCompile is like Compile, but panics instead of returning an error.

func (s Selector) Filter(nodes []*html.Node) (result []*html.Node)

Filter returns the nodes in nodes that match the selector.

func (Selector) Match

func (s Selector) Match(n *html.Node) bool

Match returns true if the node matches the selector.

func (Selector) MatchAll

func (s Selector) MatchAll(n *html.Node) []*html.Node

MatchAll returns a slice of the nodes that match the selector, from n and its children.
