We have been helping you. Apparently, you are not listening. You cannot do this. It makes no sense. You cannot insert data into the middle of a file, period, ever. That's not what a file is.
Databases, on the other hand, support this kind of operation just fine. Use a database. Insert your data with an INSERT SQL statement. Then when you need your XML (assuming you do need it at all!), use one or more SELECT statements to find the data you need, and construct your XML. Don't use XML to store data you will be adding to. That's just not what it's for.
