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:
