|

func main() {
|
||
|
|
htmlText := getSomeHtmlPage()
|
||
|
|
document, err := html.ParseDocument(htmlText)
|
||
|
|
if err != nil {
|
||
|
|
log.Fatalf("parse document: %w\n", err)
|
||
|
|
}
|
||
|
|
|
||

table := document.QuerySelector("table")

|
||
|
|
cell := row.FindOne(func(n *html.Node) {
|
||
|
|
return n.HasAttr("aria-label") && n.GetAttr("aria-label")[0] == "Value"
|
||
|
|
})
