Note 5 for XML

Watch & Read:

Lets make a XML file from a DTD

The W3C definition: An XML namespace is a collection of names, identified by a URI reference, which are used in XML documents as element types and attribute names.

Namespaces and DTDs: A namespace allows you to create predefined names that help with element naming conventions. Namespaces eliminates naming problems (collisions) such as element names that are the same but used differently!

You declare a name space as an attribute of your root element! xmlns:namespace-prefix="URL-of-namespace"

<jon:TV xmlns:jon="http://www.pvc.maricopa.edu/~storslee/xml/xml" >

Namespace Syntax is at W3schools. An example of a namespace is XS is the default namespace for Schema's

CSS give you the ability to customize your tags (or Elements). The syntax is

selector {property: value} or element name {property: value}
example: H2 {color:red} or Channel{color:blue}

Examples of CSS used with HTML (A Very Good Reference is located at W3Schools )

Just Like HTML and CSS, in XML applies to a style to each element you create.
