i have a thing on my site where the user can receive a password reminder if thye have forgot theyre password

i was wondering how i would do that

i have this so far

<%
Dim xmlDocument, path, nodes
set xmlDocument = CreateObject("MSXML2.FreeThreadedDOMDocument")
xmlDocument.async = "false"
xmlDocument.load(Server.MapPath("/speirsy/db/user.xml"))
xmlDocument.setProperty "SelectionLanguage", "XPath"

path = "/records/details[username='" & Request.Form("userQuery") & "']"
set nodes = xmlDocument.selectNodes(path)

If nodes.length = 0 Then
   Response.write("Please enter a valid username")
End If

For Each Node In nodes
   For Each Node2 In Node.childNodes
    If Node2.nodeName = "username" Then
         If Node2.text = Request.Form("UserQuery") Then
Response.Write("extratc from xml file")
else
Response.Write(" please enter a valid password")
         End If
      End If
   Next
Next


what code would i put to replace the 'extract from xml file' part
thanks
