Simply, you cannot. There is no DOM on the server, just a plain html source file. The “DOM” is the “Document Object Model”, which is an in-memory representation of the HTML elements that were parsed by the browser. Node isn’t a browser and so there is no DOM API available.

How can you traverse the DOM with JavaScript?
DOM tree traversal may be accomplished through the use of six basic properties. All properties, except childNodes, contain a reference to another node object. The childNodes property contains a reference to an array of nodes.
What is a DOM Node?
The DOM Node interface is an abstract base class upon which many other DOM API objects are based, thus letting those object types to be used similarly and often interchangeably. As an abstract class, there is no such thing as a plain Node object.
