Advanced tools
Package description
The dom-walk npm package is a utility for traversing and manipulating the DOM (Document Object Model) in a simple and efficient manner. It allows developers to walk through the DOM tree, either up or down, and apply functions or retrieve information from the DOM elements.
Walking the DOM tree
This feature allows you to traverse all nodes within a specified DOM element (e.g., document.body). The function passed to walk will be called with each node as it is visited.
var walk = require('dom-walk');
var elements = [];
walk(document.body, function (node) {
elements.push(node);
});Collecting specific elements
This code demonstrates how to use dom-walk to collect all input elements from the DOM. It walks through the DOM and conditionally pushes nodes that are input elements into an array.
var walk = require('dom-walk');
var inputs = [];
walk(document.body, function (node) {
if (node.tagName === 'INPUT') {
inputs.push(node);
}
});Cheerio is a fast, flexible, and lean implementation of core jQuery designed specifically for the server. Unlike dom-walk, which is primarily used for walking the DOM, cheerio provides a richer API for manipulating the structure and contents of the DOM, making it more suitable for complex parsing and manipulation tasks.
jsdom is a pure-JavaScript implementation of many web standards, notably the WHATWG DOM and HTML Standards, for use with Node.js. jsdom goes beyond simple DOM traversal, offering a more comprehensive simulation of a web browser's environment, which includes creating and manipulating a virtual DOM. This makes it more powerful than dom-walk for testing and scraping applications.
