A quick and dirty way to get a webpage title in Go.

gettitle.go

package main

import (
	"fmt"
	"io/ioutil"
	"net/http"
	"regexp"
)

func main() {
	url := "https://www.google.com"
	resp, err := http.Get(url)
	if err != nil {
		panic(err)
	}

	b, _ := ioutil.ReadAll(resp.Body)
	resp.Body.Close()
	body := string(b)
	// fmt.Println(body)

	openTag := regexp.MustCompile(`<title[^>]*>`)
	closeTag := regexp.MustCompile(`<\/title>`)

	ot := openTag.FindStringIndex(body)
	ct := closeTag.FindStringIndex(body)

	left := ot[1]
	right := ct[0]
	fmt.Printf("%q", body[left:right])
}
