unist-util-visit

unist utility to visit nodes.

Install

npm install unist-util-visit

Usage

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.

unist-util-visit-parents — Like visit, but with a stack of parents
unist-util-filter — Create a new tree with all nodes that pass a test
unist-util-map — Create a new tree with all nodes mapped by a given function
unist-util-remove — Remove nodes from a tree that pass a test
unist-util-select — Select nodes with CSS-like selectors
