XML has also provided the base language for communication protocols such as XMPP. XML has come into common use for the interchange of data over the Internet.
IETF RFC 7303 gives rules for the construction of Internet Media Types for use when sending XML.
In the current XHTML 1.0 Recommendation document, as published and revised to August 2002, the W3C commented that, "The XHTML family is the next step in the evolution of the Internet.
By migrating to XHTML today, content developers can enter the XML world with all of its attendant benefits, while still remaining confident in their content's backward and future compatibility." However, in 2005, the Web Hypertext Application Technology Working Group (WHATWG) formed, independently of the W3C, to work on advancing ordinary HTML not based on XHTML.
To keep the example simple this program generates a XML file from a Vector preloaded with hard coded data.
The steps involved are a) Get an instance of DOM parser b) Create a new Document c) Load the Data d) Create a DOM tree with this Data e) Print the DOM tree which will be the XML file In detail a) Get an instance of DOM psrser to the same directory where you have downloaded these programs.
When a Sax parser parses a XML document and every time it encounters a tag it calls the corresponding tag handler methods when it encounter a Start Tag it calls this method public void start Element(String name, Attribute List attrs) when it encounter a End Tag it calls this method public void end Element(String name) This program also parses a XML file and prints it on the console . In this example, the Print Using Sax Class extends the Handler Base class and implemets the call back methods to handle the printing The steps involved are Get a instance of SAX parser, The previous program illustrated how to Parse an existing XML file using both SAX and DOM Parsers.
XHTML documents are well-formed and may therefore be parsed using standard XML parsers, unlike HTML, which requires a lenient HTML-specific parser.In computing, Extensible Markup Language (XML) is a markup language that defines a set of rules for encoding documents in a format that is both human-readable and machine-readable.The W3C's XML 1.0 Specification It is a textual data format with strong support via Unicode for different human languages.a) Construction of DOM tree b) Traversing the DOM tree It does a Depth First Pre Order Traversal , for more on tree traversal techniques see here As it goes through each node it prints it contents.This snippet explains how to handle the element Node parses a XML document and prints it on the console.
