Call the arraylists add method.

Dim nlEqObjName As Xml.XmlNodeList =
doc.SelectNodes("/AutomationControl/EquipmentObjects/EquipmentObject/GeneralProperties/@ObjectName")
        Dim nEqObjName As Xml.XmlNode
        For Each nEqObjName In nlEqObjName
            arlsEqObjName.Add(nEqObjName.InnerText)
        Next
        Dim nlEqObjInstNum As Xml.XmlNodeList =
doc.SelectNodes("/AutomationControl/EquipmentObjects/EquipmentObject/GeneralProperties/@InstanceNumber")
        Dim nEqObjInstNum As Xml.XmlNode
        For Each nEqObjInstNum In nlEqObjInstNum
            arlsEqObjInstNum.Add(nEqObjInstNum.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.
