func Attr ¶

func Attr(node *html.Node, key string) string

Attr returns the value of an HTML attribute.

func Find ¶

func Find(node *html.Node, mf MatchFunc) (n *html.Node, ok bool)

Find returns the first node which matches the MatchFunc using depth-first search. If no node is found, ok will be false.

root, err := html.Parse(resp.Body)
if err != nil {
    // handle error
}
mf := func(n *html.Node) bool {
    return n.DataAtom == atom.Body
}
body, ok := scrape.Find(root, mf)

func FindAll ¶

func FindAll(node *html.Node, mf MatchFunc) []*html.Node

FindAll returns all nodes which match the provided MatchFunc. After discovering a matching node, it will _not_ discover matching subnodes of that node.

func FindAllNested ¶

func FindAllNested(node *html.Node, mf MatchFunc) []*html.Node

FindAllNested returns all nodes which match the provided MatchFunc and _will_ discover matching subnodes of matching nodes.

func FindNextSibling ¶

func FindNextSibling(node *html.Node, mf MatchFunc) (n *html.Node, ok bool)

FindNextSibling returns the first node which matches the MatchFunc using next sibling search. If no node is found, ok will be false.

root, err := html.Parse(resp.Body)
if err != nil {
    // handle error
}
mf := func(n *html.Node) bool {
    return n.DataAtom == atom.Body
}
body, ok := scrape.FindNextSibling(root, mf)

func FindParent ¶

func FindParent(node *html.Node, mf MatchFunc) (n *html.Node, ok bool)

FindParent searches up HTML tree from the current node until either a match is found or the top is hit.

func FindPrevSibling ¶

func FindPrevSibling(node *html.Node, mf MatchFunc) (n *html.Node, ok bool)

FindPrevSibling returns the first node which matches the MatchFunc using previous sibling search. If no node is found, ok will be false.

root, err := html.Parse(resp.Body)
if err != nil {
    // handle error
}
mf := func(n *html.Node) bool {
    return n.DataAtom == atom.Body
}
body, ok := scrape.FindPrevSibling(root, mf)

func Text ¶

func Text(node *html.Node) string

Text returns text from all descendant text nodes joined. For control over the join function, see TextJoin.

func TextJoin ¶

func TextJoin(node *html.Node, join func([]string) string) string

TextJoin returns a string from all descendant text nodes joined by a caller provided join function.
