XML Events - Advantages of XML Events

Advantages of XML Events

XML Events uses a separation of concerns design pattern, and is technology-neutral with regard to handlers. It gives authors freedom in organizing their code and allows separation of document content from scripting.

Legacy HTML and early SVG versions bind events to presentation elements by encoding the event name in an attribute name, such that the value of the attribute is the action for that event at that element. For example (with Javascript’s onclick attribute):

This design has three drawbacks:

  1. it hard-wires the events into the language, so that adding new event types requires changes to the language
  2. it forces authors to mix the content of the document with the specifications of the scripting and event handling, rather than allowing them to separate them.
  3. it restricts authors to a single scripting language per document.

Famous quotes containing the words advantages of, advantages and/or events:

    “When the manipulations of childhood are a little larceny, they may grow and change with the child into qualities useful and admire in the grown-up world. When they are the futile struggle for love and concern and protection, they may become the warped and ruthless machinations of adults who seek in the advantages of power what they could never win as children.”
    —Leontine Young (20th century)

    “Can you conceive what it is to native-born American women citizens, accustomed to the advantages of our schools, our churches and the mingling of our social life, to ask over and over again for so simple a thing as that “we, the people,” should mean women as well as men; that our Constitution should mean exactly what it says?”
    —Mary F. Eastman, U.S. suffragist. As quoted in History of Woman Suffrage, vol. 4 ch. 5, by Susan B. Anthony and Ida Husted Harper (1902)

    “When the world was half a thousand years younger all events had much sharper outlines than now. The distance between sadness and joy, between good and bad fortune, seemed to be much greater than for us; every experience had that degree of directness and absoluteness which joy and sadness still have in the mind of a child”
    —Johan Huizinga (1872–1945)
