The document type (DOCTYPE) declaration

Consists of an internal, or references an external Document Type Definition (DTD). It can also have a combination of both internal and external DTDs. The DTD defines the constraints on the structure of an XML document. It declares all of the document's element types , children element types, and the order and number of each element type. It also declares any attributes, entities, notations, processing instructions, comments, and PE references in the document.

  1. xmlDoc - the XML DOM object created by the parser.
  2. getElementsByTagName("title")[0] - get the first <title> element

Tools for parsing

  1. Through parsers using the API Java API for XML Processing (JAXP), two parsers are provided with the above API : Simple API for XML (SAX) & Document Object Model (DOM).
  2. Through the new API Java Architecture for XML Binding (JAXB): Using JDOM an open-source API & Using Apache Xerces
