The design goals for XML are:

1) XML shall be straightforwardly usable over the Internet.

2) XML shall support a wide variety of applications.

3) XML shall be compatible with SGML.

4) It shall be easy to write programs which process XML documents.

5) XML documents should be human-legible and reasonably clear.

6) The XML design should be prepared quickly.

7) XML documents shall be easy to create.

Main points

1) In XML you can creates meaningful tags that describes the data.

<web designer>          <fname>Travis </fname>          <lname>York   </lname> </web designer>

Some Code
This way, I can be pretty certain that anyone searching for an occurrence of "web designer" within a tag would come across my name Travis York. Furthermore, if my information was surrounded by tags like these - tags that make sense - I could tell other programs what to do with them. With just a touch of coding, I could pull the contents of the tag into an appropriate database field, then output it to a hard copy for a book.

2) You can make your own tag pairs, which allows you to describe the data you are marking up in a way that is meaningful to you.

<lname>York   </lname>

3) It provides a better way to organize data and use the data for other programs.
