Search for some values in XML files

I'm trying to retreive some data from an XML file. For example (shown below), I'm trying to get the filenumber (123456), UserID (654321), all file types (Local, network, email) and file destinations (C:\, X:\, [email protected]) to display on a form. What's the fastest and most efficient way to do it?

<FILEGROUPID>
.
.
.
<KEY>
<KeyName>FileNumber</KeyName>
<KeyValue>123456</KeyValue>
</KEY>
<KEY>
<KeyName>UserID</KeyName>
<KeyValue>654321</KeyValue>
</KEY>
.
.
.
</FILEGROUP>
.
.
.
<FileType = "LOCAL">
<FileDestination>"C:\Temp\Example.xml"<FileDestination>
</FileType>
.
.
.
<FileType = "NETWORK">
<FileDestination>"X:\Temp\Example.xml"<FileDestination>
</FileType>
.
.
.
<FileType = "EMAIL">
<FileDestination>[email protected]<FileDestination>
</FileType>
.
.
.


Thanks in advance!!!!!!!
