How to read xml file automatically

Hello Everyone

I am starting new in Unity,and I have a question about xml .

I hava an xml file this shape.
<?xml version="1.0" encoding="utf-8"?>
<Personeller>
<bilgi>
<id>141</id>
<isim>özlem</isim>
<soyisim>özlem</soyisim>
<sehir>Afyon </sehir>
<sektor>Bilişim</sektor>

I need to read in Unity ,and ı dont know C# script.
By the way,Xml file is in Resources folder.
And,If I change xml file from outside ,actually on windows,
Xml needs to change in Unity.
I have a GUIbox about xml file.

you needs to tell so kindly ,because ı am new .
Thanks for helps.
