Microdata

Microdata is a package for the Go programming language to extract Microdata from HTML5 documents.

HTML Microdata is a markup specification often used in combination with the [schema collection][3] to make it easier for search engines to identify and understand content on web pages. One of the most common schema is the rating you see when you google for something. Other schemas are persons, places, events, products, etc.

Installation

Build from source:

$ go get -u github.com/damian-szulc/microdata/cmd/microdata

Usage

Parse from URL:

$ microdata https://www.gog.com/game/...
{
  "items": [
    {
      "type": [
        "http://schema.org/Product"
      ],
      "properties": {
        "additionalProperty": [
          {
            "type": [
              "http://schema.org/PropertyValue"
            ],
{
...

Parse HTML from the stdin:

$ cat saved.html | microdata

Format the output with a Go template to return the "price" property:

$ microdata -format '{{with index .Items 0}}{{with index .Properties "offers" 0}}{{with index .Properties "price" 0 }}{{ . }}{{end}}{{end}}{{end}}' https://www.gog.com/game/...
