Go HTML Info

Go HTML Info provides a simple interface to extract meaningful information from an html page.

source docs: http://godoc.org/github.com/dyatlov/go-htmlinfo/htmlinfo

Install: go get github.com/dyatlov/go-htmlinfo/htmlinfo

Use: import "github.com/dyatlov/go-htmlinfo/htmlinfo"

Parse method parses all html content into structurized ata.
GenerateOembedFor method generate oembed info from that structurized data. It generates that info based on available data, even if no oembed information found on the page.

Example:

package main

import (
	"fmt"
	"net/http"

	"github.com/dyatlov/go-htmlinfo/htmlinfo"
)

func main() {
	u := "http://techcrunch.com/2015/09/09/ipad-pro-coming-in-november-pricing-starts-at-799/"

	resp, err := http.Get(u)

	if err != nil {
		panic(err)
	}

	defer resp.Body.Close()

	info := htmlinfo.NewHTMLInfo()

	// if url can be nil too, just then we won't be able to fetch (and generate) oembed information
	err = info.Parse(resp.Body, &u, nil)

	if err != nil {
		panic(err)
	}

	fmt.Printf("Info:\n%s\n", info)

	fmt.Printf("Oembed information: %s\n", info.GenerateOembedFor(u))
}

Result would be:

If you’re wondering when you can get your hands on it, and how much it will cost, here you go: Apple says the iPad Pro and related accessories will be available in November.\nPricing will start at $799 with 32 gigabytes of memory and WiFi-only connectivity, with a $949 price tag for 128 GB, and $1,079 for 128 GB and a cellular connection. If you want the company’s new stylus, dubbed the Apple Pencil, that’ll cost you $99, and the Smart Keyboard will cost $169.\nThat may seem pretty pricey compared to other iPads — in fact, Apple said today that it’s dropping pricing on its iPad Mini 2, which its considers to be the entry-level iPad, to $269. What you’re paying for (among other things) is a 12.9-inch screen with resolution of 2,732 x 2,048 pixels, Apple’s A9X chip and four speakers.\nAnd, as the name and on-stage demos suggest, Apple seems to be pitching this for enterprise use and productivity, not for casual use.\n\t\t\t\n\t\t\t\t\n\t\t\t\tSay Hello To The Brand-New iPad Pro\n\t\t\t\n\t\t\t\t\t\t\t\t\n\t\t\t\t\t\t\t",
