Types ¶

type Selector ¶

type Selector func(*html.Node) bool

A Selector is a function which tells whether a node matches or not.

func Compile ¶

func Compile(sel string) (Selector, error)

Compile parses a selector and returns, if successful, a Selector object that can be used to match against html.Node objects.

func MustCompile ¶

func MustCompile(sel string) Selector

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

func (Selector) Filter ¶

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.

func (Selector) MatchFirst ¶

func (s Selector) MatchFirst(n *html.Node) *html.Node

MatchFirst returns the first node that matches s, from n and its children.
