xml-zero-lexer

Friendly and forgiving CSS/SASS/LESS lexer/parser with lots of tests. Memory-efficient and Web Worker compatible.

Features

• Supports CSS, SASS and LESS.
• Zero-copy

Usage

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

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

const css = 'text { prop; prop2: value }';
const tokens = Lexx(xml);

// 'tokens' is now:
//   [
//    [NodeTypes.SELECTOR_NODE, 0, 4],
//    [NodeTypes.OPEN_RULE],
//    [NodeTypes.PROPERTY_NODE, 7, 11],
//    [NodeTypes.CLOSE_PROPERTY],
//    [NodeTypes.PROPERTY_NODE, 13, 27],
//    [NodeTypes.CLOSE_PROPERTY],
//    [NodeTypes.CLOSE_RULE]
//   ]

css.substring(tokens[0][1], tokens[0][2]);
// would return "text"
