how to import xml documentos using pyhton to read the data from it?

i have a xml document that is an output of a nmap scan, now I'm trying to import into python to be able to read the file by different elements for example:

<?xml version="1.0"?>

<data>

<country name="Liechtenstein">

<rank>1</rank>

<year>2008</year>

<gdppc>141100</gdppc>

<neighbor name="Austria" direction="E"/>

<neighbor name="Switzerland" direction="W"/>

</country>

<country name="Singapore">

<rank>4</rank>

<year>2011</year>

<gdppc>59900</gdppc>

<neighbor name="Malaysia" direction="N"/>

</country>

<country name="Panama">

<rank>68</rank>

<year>2011</year>

<gdppc>13600</gdppc>

<neighbor name="Costa Rica" direction="W"/>

<neighbor name="Colombia" direction="E"/>

</country>

</data>

if im using this file and i just want to print the countries i can do something like:

>>> for country in countr:

... print country.get('name')

...

Liechtenstein

Singapore

Panama

I'm able to do most of the thing with the element tree, like find, finfall, etc, my main problem is how to import my file into python to be able to read the data

the file is in: C:/Users/Heleno/Desktop/results/primeiro.xml

im trying to do the tutorial:

http://docs.python.org/2/library/xml.etree.element...

but still dont understand how they manage to import the file.

the bit of code i have:

import xml.etree.ElementTree as ET

tree = ET.parse('primeiro.xml')

root = tree.getroot()

i put this into python idle but i think i need to be more specific with the root where the file is
