Summary: Demonstrates how to modify an existing Flamingo nXt plant.

I am trying to figure out how to modify an existing Flamingo nXt plant. What can I do?

The following are examples of how to modify an existing Flamingo nXt plant so that it has 3 trunks.

RhinoScript

	If Err Then
		MsgBox Err.Description
		Exit Sub
	End If
	strObject = Rhino.GetObject("Select object")
  If Not IsNull(strObject) And Not strObject = "" Then
		Set plant = objPlugIn.PlantFromObject(strObject)
    If IsNull(plant) Then
      Rhino.Print("Object is not a plant")
    Else
      xml = plant.XmlWithoutHeader
      If IsNull(xml) Then
        Rhino.Print("Error extracting plant XML")
      Else
        Set xmlDoc = CreateObject("Microsoft.XMLDOM")
        If IsNull(xmlDoc) Then
          Rhino.Print("Error creating XML document")
        Else
          xmlDoc.LoadXml(xml)
          Set node = xmlDoc.SelectSingleNode("ArPlantDef/PlantDef/nTrunks")
          If IsNull(node) Or IsEmpty(node) Then
            Rhino.Print("Error getting plant XML")
          Else
            'Mofiy the trunk value changing it to 3 trunks
            node.Text = "3"
            If objPlugIn.ModifyPlantObject(strObject, xmlDoc.xml) Then
              Rhino.Print("Plant now has three trunks...")
            Else
