Node.js applications sometimes require interaction with XML, and the npm ecosystem offers over 3,400 packages to facilitate this. This article examines several popular npm packages for handling XML in Node.js, such as xml2js, libxmljs2, Cheerio, and svgson, each serving unique purposes like parsing, validating, or manipulating XML and HTML. xml2js allows bidirectional conversion between XML and JavaScript, working well with the Express framework when combined with express-xml-bodyparser middleware. libxmljs2 supports XML schema validation, ensuring data integrity during exchanges. Cheerio, though primarily for HTML, can manipulate HTML fragments and automatically corrects non-compliant HTML. svgson simplifies the manipulation of SVG images by converting them into JSON, enabling dynamic styling through JavaScript. The article provides practical examples to demonstrate how each package can be integrated into Node.js applications, emphasizing their utility in different XML-related tasks.
