Extract Nodes by Type
EPAMLuxoftGrammarly
Write a function extractNodesByType(root, type) that takes a DOM tree root and node type, and returns all nodes of that type in a flat array.
Each node has a tagName property and optionally a children array containing child nodes.
Example:
Input: root = { tagName: "div", children: [{ tagName: "span" }, { tagName: "p" }] }, type = "span"
Output: [{ tagName: "span" }]
Examples:
Input 1:
{"root":{"tagName":"div","children":[{"tagName":"span"},{"tagName":"p"}]},"type":"span"}Output 1:
[{"tagName":"span"}]Input 2:
{"root":{"tagName":"div","children":[]},"type":"span"}Output 2:
