I search for a few days how to parse my xml file.
So my problem I will want to recover all the key-values of the root element .

Exemple of file:

```
<?xml version="1.0" ?>
<!DOCTYPE ....... SYSTEM ".....................">
<coverage x="y1"  x2="y2"  x3="y3"  x4="y4">
    <sources>
      <source>.............</source>
    </sources>
    .....
<\coverage>

```

Here, i will want to Recover all the value of "coverage" : x1 and his value , x2 and his value, x3 and his value x3...
I have already tried using "XmlReader" with all the tutorial i have could find but it still does not work.
All tutorials I've could tried, recover a value in a certain node (tag), but never all the values of the root element.

Maybe a tutorial with this same problem already exist but i haven't found him.

Thank you in advance for your help.
