Semantic Schema Parser

A Nodejs module to extract http://schema.org micro-data from HTML and convert it in a JSON object.

Install

npm install semantic-schema-parser

How use it

//set a list of URLs
var schema = require("semantic-schema-parser");
var urls  = [
    "http://www.imdb.com/title/tt0096874/",
    "http://www.imdb.com/title/tt0087469/"
    ];
    
//Be happy

schema.parseURLs(urls, 
  // set a callback
  function(msg){
   // returns a JSON;
   msg = JSON.stringify(msg);
   // do something
});

You also can send the content you want to parse as a string using the parseContent function:

  var schema = require("semantic-schema-parser");
  var myString = "<html><head></head><body>...etc...</body></html>"
  schema.parseContent(myString, function(msg){
      // returns a JSON;
      msg = JSON.stringify(msg);
      // do something
  });

Example

Get in the example folder and run the command node main.js

The example will create a file named result.json based in a URLs list. That file have a text example of the generated JSON object.

Probably , It'll be something like that:
