Summary: memory leak in pyexpat parser

Details: Hi,
I am having a problem with memroy when I am running a python program which
has a code similar to this. 

from xml.dom import minidom

while 1:
  doc = minidom.parse('text.xml')
  print doc
  del doc

The memory size keeps incrementing as the loop is executed.This is the
text.xml file

<?xml version="1.0"?>
  <Nesim>
    <config>
      <port>50008</port>
      <Sustained-alarm-rate>10</Sustained-alarm-rate>
      <Burst-alarm-rate>10</Burst-alarm-rate>
      <Burst-duration>10</Burst-duration>
      <Burst-frequency>10</Burst-frequency>
    </config>
   </Nesim>

I am trying to delete it manually even then the memory size is increasing.
Please I need some help .

Thanks
kishore

Comment:
This has to do with minidom, not pyexpat.  minidom creates internal
circular references which need to be cleared by calling the .unlink()
method on the document object.  See the development copy of the
documentation for more information:
