Under the DOM model, the first child node in <server> is a text node 
containing the whitespace between <server> and <config>.  If you know there 
is only one threads element under each server you can use:

for server in serverelements:
    print server.getElementsByTagName('threads')[0].childNodes[0].data

But you will probably find ElementTree a much more useful xml library:

from xml.etree import ElementTree
tree = ElementTree.parse("/home/grinder/grinder-3.0.1/data/reportsInfo.txt")
print tree.find('config/threads').text
