unist utility to visit nodes.

Install

npm:

npm install unist-util-visit

Use

var u = require('unist-builder')
var visit = require('unist-util-visit')

var tree = u('tree', [
  u('leaf', '1'),
  u('node', [u('leaf', '2')]),
  u('void'),
  u('leaf', '3')
])

visit(tree, 'leaf', function(node) {
  console.log(node)
})

Yields:

{ type: 'leaf', value: '1' }
{ type: 'leaf', value: '2' }
{ type: 'leaf', value: '3' }

API

visit(tree[, test], visitor[, reverse])

This function works exactly the same as unist-util-visit-parents, but visitor has a different signature.

next? = visitor(node, index, parent)

Instead of being passed an array of ancestors, visitor is invoked with the node’s index and its parent.

Otherwise the same as unist-util-visit-parents.
