What is w3c-xmlserializer?
The w3c-xmlserializer npm package is used to serialize DOM nodes to XML strings, following the W3C specification. It is typically used to convert DOM trees into a format that can be easily transported or stored.
Serializing DOM Nodes
This feature allows you to serialize a DOM node (such as an entire document or an individual element) to a string that contains XML. The code sample demonstrates how to create an instance of XMLSerializer and use it to serialize a DOM document to an XML string.
const { XMLSerializer } = require('w3c-xmlserializer');
const serializer = new XMLSerializer();
const xmlString = serializer.serializeToString(document);
