A simple example to read HTML title via goquery in Golang.
Install goquery:
$ go get -u github.com/PuerkitoBio/goquery
Source code:
title.go | repository | view raw
package main
import (
"flag"
"fmt"
"github.com/PuerkitoBio/goquery"
"os"
)
func processHTML(path string) {
f, err := os.Open(path)
if err != nil {
panic(err)
}
defer f.Close()
doc, err := goquery.NewDocumentFromReader(f)
if err != nil {
panic(err)
}
title := doc.Find("title").Text()
fmt.Println(title)
}
func main() {
pPath := flag.String("input", "", "Path of file to be processed")
flag.Parse()
path := *pPath
if path == "" {
fmt.Fprintf(os.Stderr, "Error: empty path!\n")
return
}
processHTML(path)
}
