DOM Traverse Utility
Example (Browser)
1. Basic traverse
import traverse from "dom-traverse";
// Analogous to document.querySelectAll('*')
for (const node of traverse(document.body, Node.ELEMENT_NODE)) {
// Do something ...
}2. Skippable traverse - ignore part of the DOM
import traverse from "dom-traverse";
for (const [node, skip] of traverse.skippable(
document.body,
Node.ELEMENT_NODE
)) {
if (node.tagName === "H1") {
// Do something ...
} else {
// Child elements of this node will NOT be iterated.
skip();
}
}Use with Node.JS
// interface `Node` is not available in NodeJS
import traverse, { Node } from "dom-traverse";
import { JSDOM } from "jsdom";
const dom = new JSDOM("<html><!-- your html content --></html>");
for (const node of traverse(dom.window.body, Node.ELEMENT_NODE)) {
// Do something ...
}
