Go Web Scraping Quick Start Guide

Example – Counting links

One quick and easy piece of information that we could extract using the strings package is to count the number of links that are contained in a web page. The strings package has a function called Count(), which returns the number of times a substring occurs in a string. As we have seen before, links are contained in <a> tags. By counting the number of occurrences of "<a", we can get a general idea of the number of links in a page. An example would look like the one given here:

package mainimport (  "fmt"  "io/ioutil"  "net/http"  "strings")func main() {  resp, err := http.Get("https://www.packtpub.com/")  if err != nil {    panic(err)  }  data, err := ioutil.ReadAll(resp.Body)  if err != nil {    panic(err)  } stringBody := string(data) ...
