More examples

Example: AJAXed page

Note: script tags are not executed, but other on* handlers will run normally once attached to the document.

const response = await fetch('page.html');
const html = await response.text();
const dom = doma(html);
const ajaxedContent = dom.querySelector('#ajax-container').childNodes;

const ajaxedContainer = document.querySelector('#ajax-container');
ajaxedContainer.append(...ajaxedContent);

Example: Parse images from HTML

Note: images are not fetched when the HTML is parsed. The elements only become "active" (and start loading) once appended to the document.

const html = 'They say it’s round <img src="earth.jpg"> but actually it’s banana-shaped <img src="banana.tiff">';
const dom = doma(html);
// =>  DocumentFragment[Text('They say it’s round '), <img>, Text(' but actually it’s banana-shaped ', <img>]

const images = dom.querySelectorAll('img');
// =>  NodeList[<img>, <img>]

Example: Drop HTML tags from string

const html = '<em>Never</em> gonna give you <sup>up</sup>, never gonna let you <sub>down</sub>';
const string = doma(html).textContent;
// =>  'Never gonna give you up, never gonna let you down'
