Functions

func Children

func Children(n xml.Node) (nodes xml.Nodes)

func ElementNode

func ElementNode(n xml.Node) xml.Node

func GetAttr

func GetAttr(n xml.Node, key string) *string

Types

type Checker

type Checker func(xml.Node) xml.Node

func And

func And(cs ...Checker) Checker

func AtomChecker

func AtomChecker(a string) Checker

func Find

func Find(cs ...Checker) Checker

Broad first search in all descendants

func Not

func Not(c Checker) Checker

func Or

func Or(cs ...Checker) Checker

func Pipe

func Pipe(cs ...Checker) Checker

type Node

type Node struct {
	xml.Node
}

Node represents a HTML node. Wrap html.Node so that chainable interface is possible Use pointer of it because we want to test with nil.

func NewSvg

func NewSvg() *Node

func Parse

func Parse(r io.Reader) (*Node, error)

func (*Node) AddChild

func (n *Node) AddChild(c *Node)

func (*Node) Attr

func (n *Node) Attr(key string) *string

func (*Node) Find

func (n *Node) Find(cs ...Checker) *Node

func (*Node) G

func (n *Node) G(cs ...Checker) *Node

func (*Node) SetAttr

func (n *Node) SetAttr(key, value string)

func (*Node) Svg

func (n *Node) Svg(cs ...Checker) *Node

type Queue

type Queue struct {
	// contains filtered or unexported fields
}

FIFO queue.

func NewQueue

func NewQueue() *Queue

func (*Queue) Len

func (q *Queue) Len() int

func (*Queue) Pop

func (q *Queue) Pop() xml.Node

func (*Queue) Push

func (q *Queue) Push(n xml.Node)
