parse5-traverse

Simple but flexible AST traversal with pre and post visitors. The main code of this project comes from ast-traverse. As ast-traverse is not compatible with parse5, parse5-traverse got created.

Getting started

$ npm install --save parse5-traverse

Usage

const parse5 = require('parse5');
const traverse = require('parse5-traverse');

const documentFragment = parse5.parseFragment('<table></table>');

// print AST node types, pre-order (node first, then its children)
traverse(ast, {
  pre(node, parent) {
    // node -> the current node
    // parent -> the parent node
  }
  post(node, parent) {
  }
});
