What are namespaces in XML?

Each tag in an XML file should have a unique name. However, you might have a tag name that means one thing in one context, but a different thing in a different context. For this, you have namespaces to uniquely identify the tags.

Example

<education:onlineCourse>

In the above example:

  • education is the namespace.
  • onlineCourse is the tag.
  • The namespace acts as a "prefix" to the tag. They are separated by a colon.
