XMlSerialization - Append to existing object

[RJN]

Hi

I'm using XMlSerailizer to write certain content to file. If the file
exists, I'm supposed to append the xml to the file.

eg.,

<EmployeeList>
<Employee></Employee>
</EmployeeList>

Assume when serializing for the first time, I get an xml like the above.
When I further serialize employee records when the application is run
next time, I'm supposed to append it to the list of employees that
already exist. If I use streamwriter to append the file, it writes after
the closing tag of EmployeeList. One way is to deserialize the existing
xml, then add the new employees into this object and then again
serialize. But this will be a huge overhead. Is there better way of
doing this?

Regards
