Here's how to navigate the DOM tree. That is, if you have a node, you can get its parent node, sibling node, or children nodes.

Get Previous/Next Sibling

// their difference is possibility of whitespace node

document .getElementsByTagName("p")[0].nextElementSibling; // never whitespace node

document .getElementsByTagName("p")[0].nextSibling; // may be whitespace node

Get Child Nodes

// example of getting children elements

const xx = document .getElementsByTagName("div")[0].childNodes;
