You should have a look at http://go-colly.org . I've done scraping with
html.Parse before, and I wish Colly existed when I did.

i am trying html Parse method from "html"* package but can't find element
"img" ...*
*Any ideas?*
var f func(*html.Node)
f = func(n *html.Node) {
if n.Type == html.ElementNode { //&& n.Data == "alt" {
for _, a := range n.Attr {
//if a.Key == "img" {
I would start by isolating the alt=“…” string with splits
(https://golang.org/pkg/strings/#Split) then use Sscanf
(https://golang.org/pkg/fmt/#Sscanf) to parse the number. There may be
other approaches like regular expressions.
