HtmlParser

HTML parser.

Takes a HTML string, creates a temporary DOM document, sets the HTML as innerHTML of the body of the temporary document, and provides methods for extracting elements from the temporary document.

Example:

Parse a single html element and get the Element

let htmlParser = new HtmlParser('<div>Test</div>');
let divElement = htmlParser.firstRootElement;

Parse multiple html elements

let htmlParser = new HtmlParser('<div>Test</div><p>Test 2</p>');
let elements = htmlParser.rootElements;

Parse multiple html elements and query them

let htmlParser = new HtmlParser('<div>Test</div><p>Test 2</p>');
let elements = htmlParser.rootElements;

Parse multiple html elements and query them

let htmlParser = new HtmlParser('<p>Test P 1</p><div>Test DIV</div><p>Test P 2</p>');
let divElement = htmlParser.querySelector('div');
let pElements = htmlParser.querySelectorAll('p');

Parse a full HTML document

let htmlParser = new HtmlParser('<html><body><p>Test</p></body></html>');
let pElement = htmlParser.firstRootElement;
