minidom

Small DOM level 1 implementation

minidom

A small JavaScript DOM. Implements DOM level 1, with textContent from level 3 and innerHTML and outerHTML getters. Only supports HTML documents.

var minidom = require("minidom");
 
var document = minidom('<!doctype><html><head><title>Hello</title><body><h1>Hi!</h1></body></html>');
 
expect(document.getElementsByTagName("h1")[0].textContent).toEqual("Hi!");

You can also access the DOM implementation used internally:

var dom = require("minidom/dom");
 
var document = minidom();
expect(document instanceof dom.Node).toBeTruthy();
JSDom minidom
Runs Javascript in the page context Yes No
CSSOM Yes No
Loads remote resources Yes No
HTML5 parsing algorithm No Yes*
Runs in the browser No Yes**
Awesome Yes Yes

Basically minidom does a lot less, but often it's all you need.

* This means that the DOM representation is the same as you would get in the browser, but may not be suitable if you wish to preserve as much of the original formatting as possible. For example parsing <body>hi</body><head><title>hello</title> with minidom results in a document that looks like <html><head></head><body>hi<title>hello</title></body></html>, where as JSDom outputs <html><body>hi</body><head><title>hello</title></head></html>.

** This is probably very cool, although I have no idea why.
