xml-zero-lexer

Friendly and forgiving HTML5/XML5/JSX lexer/parser with lots of tests. Memory-efficient and Web Worker compatible.

Parses HTML/XML/React JSX into tokens.

Features

Supports HTML, XML, and JSX.
Zero-copy

Usage

This is a zero-copy lexer/parser so it returns an array of offsets.

import Lexx, { NodeTypes } from 'xml-zero-lexer';

const xml = '<p>his divine shadow</p>';
const tokens = Lexx(xml);

// 'tokens' is now:
//   [
//     [NodeTypes.ELEMENT_NODE, 1, 2],
//     [NodeTypes.TEXT_NODE, 3, 20],
//     [NodeTypes.CLOSE_ELEMENT],
//   ]

xml.substring(tokens[0][0], tokens[0][1]);
// would return "p"

xml.substring(tokens[1][0], tokens[1][1]);
// would return "his divine shadow"
