What database system are you using? Most relational database systems
provide some form of rel->XML mapping functionality that will take care
of the entitization. See the XML Publishing functions in Oracle or DB2
or the "FOR XML" clause in SQL Server...

In SQL Server 2005 for example, the following query would give you the
required transformation (with taking care of entitization of <,> etc):

SELECT "User name" as "name", description
FROM table
FOR XML PATH('person'), ROOT('Data')

Best regards
Michael
