11 Dom

• STEP 1: What is the DOM?
  "The W3C Document Object Model (DOM) is a platform and language neutral interface that allows programs and scripts to dynamically access and update the content, structure, and style of a document."
  The W3C DOM provides a standard set of objects for representing HTML and XML documents, and a standard interface for accessing and manipulating them.
  The DOM is separated into different parts (Core, XML, and HTML) and different levels (DOM Level 1/2/3):
  
  STEP 2: HTML DOM
  The HTML DOM is the Document Object Model for HTML.
  The HTML DOM defines a standard set of objects for HTML, and a standard way to access and manipulate HTML documents.
  The HTML DOM views HTML documents as a tree structure of elements. All elements, along with their text and attributes, can be accessed and manipulated through the DOM tree.
  
  STEP 3: DHTML DOM
  The Document Object Model gives us access to every element in a document.
  
  STEP 4: XML DOM
  The XML Document Object Model (XML DOM) defines a standard way for accessing and manipulating XML documents.
  The DOM presents an XML document as a tree-structure (a node tree), with the elements, attributes, and text defined as nodes.
