# Metabolize

[![Build Status](https://travis-ci.org/keighl/metabolize.png?branch=master)](https://travis-ci.org/keighl/metabolize) [![Coverage Status](https://coveralls.io/repos/keighl/metabolize/badge.svg)](https://coveralls.io/r/keighl/metabolize)

Decodes HTML  values into a Golang struct. Great for quickly grabbing [open graph](http://ogp.me/) data.

### Installation

    go get -u github.com/keighl/metabolize

### Usage

Use `meta:"xxx"` tags on your struct to tell metabolize how to decode metadata from an HTML document.

```go

type MetaData struct {

    Title string `meta:"og:title"`

    // If no `og:description`, will fall back to `description`

    Description string `meta:"og:description,description"`

}

```

Example

```go

package main

import (

    "fmt"

    m "github.com/keighl/metabolize"

    "net/http"

    "net/url"

)

type MetaData struct {

    Title       string  `meta:"og:title"`

    Description string  `meta:"og:description,description"`

    Type        string  `meta:"og:type"`

    URL         url.URL `meta:"og:url"`

    VideoWidth  int64   `meta:"og:video:width"`

    VideoHeight int64   `meta:"og:video:height"`

}

func main() {

    res, _ := http.Get("https://www.youtube.com/watch?v=FzRH3iTQPrk")

    data := new(MetaData)

    err := m.Metabolize(res.Body, data)

    if err != nil {

        panic(err)

    }

    fmt.Printf("Title: %s\n", data.Title)

    fmt.Printf("Description: %s\n", data.Description)

    fmt.Printf("Type: %s\n", data.Type)

    fmt.Printf("URL: %s\n", data.URL.String())

    fmt.Printf("VideoWidth: %d\n", data.VideoWidth)

    fmt.Printf("VideoHeight: %d\n", data.VideoHeight)

}

```
