If your concern is the physical act of efficiently adding data to an
existing file (such as what happens to log files) then I think the two
ways to do this would be

-1- Dont add the closing tag until you're finished adding data to the
file. Simply append each xml-snippet as needed.  If you need to manipulate
the file before you're done then create a copy that has a closing tag.


-2- Each time you prepend the next set of data you need to truncate the
file slightly to remove the last line (containing the closing tag).  If
the closing tag is a constant then you know the length to truncate,
otherwise you need to examine the last N bytes to find the location of the
last tag, and truncate enough bytes to remove it before appending the new
data.
