Problem when addinag a RibbonLabel to the Ribbon in word 2007

Hi all,

        Currently i am working on Ms-Word 2007 Addin. Here I am using an xml file to generate the Ribbon labels dynamically. Please find the attached xml code.

<Groups>

      <LabelGroup>

        <GroupName>grpDocumentInformationGroupName>

        <GroupLabel>Document  InformationGroupLabel>

        <Labels>

          <Label>

            <LabelName>lblReferenceNoLabelName>

            <LabelText>Reference No:LabelText>

          Label>

          <Label>

            <LabelName>lblReferenceTypeLabelName>

            <LabelText>Reference Type:LabelText>

          Label>

          <Label>

            <LabelName>lblCreatedByLabelName>

            <LabelText>Created ByLabelText>

          Label>

          <Label>

            <LabelName>lblDocumentTypeLabelName>

            <LabelText>Document Type:LabelText>

          Label>

        Labels>

      LabelGroup><Groups>

        I am getting this xml and my code follows like this:
       
        

XmlNodeList labelGroupsList = xmlDoc.DocumentElement.SelectNodes("//Groups/LabelGroup");

 

foreach (XmlNode group in labelGroupsList)

            {

                rGroup = new RibbonGroup();

                rGroup.Name = group.SelectSingleNode("GroupName").InnerText;

                rGroup.Label = group.SelectSingleNode("GroupLabel").InnerText;

 

                XmlNodeList labelElements = group.SelectNodes("Labels");

                foreach (XmlNode labelList in labelElements)

                {

                    XmlNodeList labels = labelList.SelectNodes("Label");

                    foreach (XmlNode label in labels)

                    {

                        rLabel = new RibbonLabel();

                        rLabel.Name = label.SelectSingleNode("LabelName").InnerText;

                        rLabel.Label = label.SelectSingleNode("LabelText").InnerText;

                        rLabel.Enabled = true;

                        rLabel.ShowLabel = true;

                        rGroup.Items.Add(rLabel);

                    }

                }

                tab1.Groups.Add(rGroup);

            }

  I am getting  problem when i am adding the Label to the Group(as indicated in green color).if  that line is commented, i will get an empty group.

  Please help me adding the label to the group.

Thanks,
