Parsing HTML with Movian.

Starting with version 4.9.389 Movian features a HTML parsing library called gumbo (see https://github.com/google/gumbo-parser). This allows parsing of a HTML DOM using APIs not very different from a normal browser.

To use it first do:

var html = require('showtime/html');

Then to parse a DOM, simply do:

var dom = html.parse('<html><body><h1>This is a heading</h1></body></html>');

The returned object contains two objects

{
 document: {},
 root: {}
}

root corresponds to the <html> element.

Element have a limited set of methods to what's available in a browser. If you find something important missing here, please let us know.
