html-dom-parser
HTML to DOM parser that works on both the server (Node.js) and the client (browser):
HTMLDOMParser(string[, options])
The parser converts an HTML string to a JavaScript object that describes the DOM tree.
Example
const parse = require('html-dom-parser');
parse('<p>Hello, World!</p>');Output:
[
Element {
type: 'tag',
parent: null,
prev: null,
next: null,
startIndex: null,
endIndex: null,
children: [
Text {
type: 'text',
parent: [Circular],
prev: null,
next: null,
startIndex: null,
endIndex: null,
data: 'Hello, World!'
}
],
name: 'p',
attribs: {}
}
]Install
NPM:
npm install html-dom-parser --saveYarn:
yarn add html-dom-parserCDN:
<script src="https://unpkg.com/html-dom-parser@latest/dist/html-dom-parser.min.js"></script>
<script>
window.HTMLDOMParser(/* string */);
</script>Usage
Import or require the module:
// ES Modules
import parse from 'html-dom-parser';
// CommonJS
const parse = require('html-dom-parser');Parse empty string:
parse('');Output:
[];Parse string:
parse('Hello, World!');[
Text {
type: 'text',
parent: null,
prev: null,
next: null,
startIndex: null,
endIndex: null,
data: 'Hello, World!'
}
]Parse element with attributes:
parse('<p class="foo" style="color: #bada55">Hello, <em>world</em>!</p>');Output:
[
Element {
type: 'tag',
parent: null,
prev: null,
next: null,
startIndex: null,
endIndex: null,
children: [ [Text], [Element], [Text] ],
name: 'p',
attribs: { class: 'foo', style: 'color: #bada55' }
}
]The server parser is a wrapper of htmlparser2 parseDOM but with the root parent node excluded.
The client parser mimics the server parser by using the DOM API to parse the HTML string.
