Dim myArrayList As New ArrayList
myArrayList.Add (WhateverDataOb jectHere)

Dim nlEqObjName As Xml.XmlNodeList =
doc.SelectNodes ("/AutomationContr ol/EquipmentObject s/EquipmentObject/GeneralProperti es/@ObjectName")
Dim nEqObjName As Xml.XmlNode
For Each nEqObjName In nlEqObjName
arlsEqObjName.A dd(nEqObjName.I nnerText)
Next
Dim nlEqObjInstNum As Xml.XmlNodeList =
doc.SelectNodes ("/AutomationContr ol/EquipmentObject s/EquipmentObject/GeneralProperti es/@InstanceNumber ")
Dim nEqObjInstNum As Xml.XmlNode
For Each nEqObjInstNum In nlEqObjInstNum
arlsEqObjInstNu m.Add(nEqObjIns tNum.InnerText)
Next

when the user click the select button again after chosing another xml file,
the pervious selected data from the pervious xml files are replace when
calling the above sub. how do i retain the pervious data and append the new
data.
