DOM - Node


In DOM, every markup in an (XML|HTML) document is a node represented in a tree view.

Every DOM node has at least:

  • a type,
  • a name,
  • and a value, which might or might not be empty.


    <title>My Title</title>
    <h1>My First chapter</h1>
    <p>My Text and<a href="gerardnico.html">My Link</a></p>

  ELEM: nodeName="html" local="html"
