dynamic table name

I would like to be able to write a generic select statement where I can pass in data elements and a tablename. Example:

IS

tableName varchar2(10);
dataElements varchar2(60);

tableName := getTableName(arg);
dataElements := getDataElements(args);

// dataElements could have "element1,element2,element3,element4".
//tableName could have "msgType"

select dataElements from tableName where ...

Can this be done??? If so, how???
