Is there any reason to compare XML to CSV?

Write

<root><![CDATA[

..contents of your CSV file..

]]></root>

and you have XML file.

Yes, need to escape "]]>".

Yes, need to add some funcionality to your CSV parser to skip first and last rows.

But yes, you can include all the family of CSV files, etc. This will need a little more logic from your parser.

But someone wrote and test this, and name it XML.
