XML What is it good for?

We use XML all the time, but it depends on the data what is the best for your project.

HTML is maybe the best example, so your using a form of XML when opening a website.

<HTML>
<BODY>
Hello World!
</BODY>
</HTML>

XML can be used for many things and is ideal if every object have a different amount of options.

<OBJECT1>
<OPTION1>
</OPTION1>
<OPTION2>
</OPTION2>
</OBJECT1>
<OBJECT1>
<OPTION1>
</OPTION1>
</OBJECT1>

If I want to use the same options for object I would rather go for a CSV type of data file.

"OBJECT1","OPTION1","OPTION2"
"OBJECT2","OPTION1","OPTION2"
"OBJECT3","OPTION1","OPTION2"
