<Component Id="2"><Color></Color>
<Component Id="2"><Color></Color>
<Component Id="4"><Color></Color>
<Component Id="5"><Color></Color>
<Component Id="6"><Color></Color>
<Component Id="6"><Color></Color>
<Component Id="8"><Color></Color>
<Component Id="9"><Color></Color>
</Model>

IN the above XML code Id="2" and Id="6" is repeated.
Do I want to find out the missing values from sequence.
I have to replace the repeated values with nearest possible values

Example:

The Output should be:

XML

<Model>
<Component Id="1"><Color></Color>
<Component Id="2"><Color></Color>
<Component Id="3"><Color></Color>
<Component Id="4"><Color></Color>
<Component Id="5"><Color></Color>
<Component Id="6"><Color></Color>
<Component Id="7"><Color></Color>
<Component Id="8"><Color></Color>
<Component Id="9"><Color></Color>

Please refer following code, i have added closing tags for Component tags:-

XML

string szXML = "<Model>" +
                           "<Component Id='1'><Color></Color></Component>" +
                           "<Component Id='2'><Color></Color></Component>" +
                           "<Component Id='2'><Color></Color></Component>" +
                           "<Component Id='4'><Color></Color></Component>" +
                           "<Component Id='5'><Color></Color></Component>" +
                           "<Component Id='6'><Color></Color></Component>" +
                           "<Component Id='6'><Color></Color></Component>" +
                           "<Component Id='8'><Color></Color></Component>" +
                           "<Component Id='9'><Color></Color></Component>" +
                        "</Model>";

           XmlDocument objDOM = new XmlDocument();
           objDOM.LoadXml(szXML);//you can specify file name here
           for (int iIndex = 0; iIndex < objDOM.DocumentElement.ChildNodes.Count; iIndex++)
           {
               objDOM.DocumentElement.ChildNodes[iIndex].Attributes["Id"].Value = (iIndex + 1).ToString();
           }
           //objDOM.Save(szFileName) //if xml loaded from File
