XML - Why use it?

• Key issue is the separation of structure from presentation
• Tags can be arbitrary, and have no meaning. Hence they can be chosen by the author to reflect the logical organization of the document.

  Example 2

• Document has high level of structure, so more meaningful searches are possible.

  Example 3 Search for images of 1210: look in <descr> field, not <size>

• Rendering the document for presentation is kept entirely separate, and can be done more than one way for different display purposes.
