How to get text content from iFrame?

[mxschmitt]

Something like this would work:

package main

import (
	"fmt"
	"log"

	"github.com/mxschmitt/playwright-go"
)

func main() {
	pw, err := playwright.Run()
	if err != nil {
		log.Fatal(err)
	}
	browser, err := pw.Chromium.Launch()
	if err != nil {
		log.Fatalf("could not launch browser: %v\n", err)
	}
	page, err := browser.NewPage()
	if err != nil {
		log.Fatalf("could not create page: %v\n", err)
	}
	if err := page.SetContent(`<iframe id="foobar" src="https://playwright.dev"></iframe>`); err != nil {
		log.Fatalf("could not goto: %v\n", err)
	}

	frameElement, err := page.QuerySelector("#foobar")
	if err != nil {
		log.Fatalf("could not find #foobar iframe: %v\n", err)
	}
	frame, err := frameElement.ContentFrame()
	if err != nil {
		log.Fatalf("could not get content frame: %v\n", err)
	}
	fmt.Println(frame.URL())
	fmt.Println(frame.InnerHTML("body"))

	if err := browser.Close(); err != nil {
		log.Fatalf("could not close browser: %v\n", err)
	}
	if err := pw.Stop(); err != nil {
		log.Fatalf("could not stop Playwright: %v\n", err)
	}

}
