Functions

func AllFn

func AllFn(okRes bool, filters ...func(*html.Node) bool) func(*html.Node) bool

AllFn gets a slice of filters and returns new filter func. This function calls each filter from the slice with given *html.Node and returns okRes if all filters return true otherwise this function returns !okRes.

func AnyFn

func AnyFn(okRes bool, filters ...func(*html.Node) bool) func(*html.Node) bool

AnyFn gets a slice of filters and returns new func. This function calls each filter from the slice with given *html.Node and returns okRes if any call of filter returns true. If all filters returns false this function returns !okRes.

func Attr

func Attr(n *html.Node, key string) (string, bool)

Attr returns attribute of node by given key if any.

func Children

func Children(n *html.Node, filter func(*html.Node) bool) []*html.Node

Children returns slice of nodes where each node is a child of given node and filter function returns true for corresponding child node.

func Find

func Find(n *html.Node, filter func(*html.Node) bool) *html.Node

Find walks through tree of nodes and call filter function for each one and returns node if filter returns true.

func JoinData

func JoinData(n ...*html.Node) string

JoinData returns attribute of node by given key if any.

func Traverse

func Traverse(n *html.Node, check func(*html.Node) bool, nodes []*html.Node) []*html.Node

Traverse walks through tree of nodes and adds visited node to the slice if check function returns true for this node.
