How to read the attributes of an XML file with VB.Net

Hello friends
I would love to have your help with a blocking for hours.
In summary, I have to read an XML file and retrieve information with the VB.Net language.
I would like to recover the "name", the "checkvalue" and the "compositekey"
That's the structure of my xml file:
<supercollection name="BF000000.hks"> <collections> <collection maxdukptkeyindex="17" maxmskeyindex="13" merchantid="" applicationcertificate="Only Collection Certificate" applicationname="Only Collection Application" name="Only Collection"> <mskeys> <key index="1" checkvalue="E8F71A" variantindex="0" verifycheckvalue="yes" keylength="32" compositekey="BA03BDBDF091092C26B9D22A2922F504" usage="1" encryptionmode="TECB" name="Key"> <type>Master</type> </key> </mskeys> <dukptkeys></dukptkeys> </collection> </collections> </supercollection>
