You can create a copy of all nodes in a document, and trims the nodeValue of each node if it exists.

const copyChildrenNodesWithoutWhiteSpace = (document) => {
  const clone = document.cloneNode();

  for (const child of document.childNodes) {
    const childCopy = copyChildrenNodesWithoutWhiteSpace(child);
    clone.appendChild(childCopy);

    if (childCopy.nodeValue) {
      childCopy.nodeValue = childCopy.nodeValue.trim();
    }
  }

  return clone;
};

const result = copyChildrenNodesWithoutWhiteSpace(anyDocument);
