ptrcnull/html

library wrapping net/html with a bunch of convenience functions

example usage:

package main

import (
  "log"
  "os"

  "git.ddd.rip/ptrcnull/html"
)

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

  table := document.QuerySelector("table")
  if table == nil {
    log.Fatalln("table not found")
  }

  if os.Getenv("DEBUG") == "1" {
    log.Println("table:", table.Render())
  }

  for _, row := range table.QuerySelectorAll("tr") {
    if strings.Contains(row.Text(), "a thing you're looking for") {
      cell := row.FindOne(func(n *html.Node) {
        return n.HasAttr("aria-label") && n.GetAttr("aria-label")[0] == "Value"
      })

      log.Println("value:", cell.TrimmedText())
    }
  }
}
