Sort XML File and use with asp dropdown

Hi

I've got an XML file that I use to populate an asp treeview control and a dropdown box. That works fine, although I now want to be able to sort the list of people in the dropdown list. Someone suggested using an XML template, but I'm a bit of an XML newbie and not sure how to do this. Can someone help.

This is what I've got to get the usernames out of the xml file and update fill the dropdown

Sub BuildXMLUsers()
'This loops thru the XML file and recursively calls ListXMLUSers to update the combo
'Restricts the combo to ONLY show the users listed in the XML file

dim oXMLNode
Dim sUniqueFileName
Dim iAdminUser, x, y, sDocument

'Gets the Querystring => retrieve the correct XML file
sDocument = document.location

x = instr(1,sDocument,"iAdmin=")
y = len(sDocument)

iAdminUser = right(sDocument, y - (x + 6))
sUniqueFileName = "XML/admin_users_" & iAdminUser & ".xml"

with oXML.XMLDocument
.async = false
if .load(sUniqueFileName) then
call ListXMLUsers(oXML.SelectSingleNode("/xml/user"))
else
msgbox "Couldn't load xml file because " & .parseError.reason
end if
end with

end sub

Sub ListXMLUsers(oXMLNode)
Dim oOption ' as object

set oOption = document.createElement("option")
call frmUser.cmbManager.options.add(oOption)

oOption.innerText = oXMLNode.selectSingleNode("@name").nodeValue
oOption.value = oXMLNode.selectSingleNode("@id").nodeValue

for each oXMLSubNode in oXMLNode.selectNodes("user")
Call ListXMLUsers(oXMLSubNode)
next

End Sub

Thanks
