xml parsing memory leak

[keepyourstupidspam]

In the code below I am trying to read text in an xml file, this works
fine but creates a memory leak of about 400K each time. This code is
called from a loop in a windows service so I can not just terminate the
app to cleanup, any ideas how to free this memory.
