You can use a XPath query to locate the element based on the id. For example something like:

C#

System.Xml.XmlDocument xmlDoc = new System.Xml.XmlDocument();

         xmlDoc.LoadXml(@"
<DataDownload>
  <ClusterId id=""00 15"">
    <attrib>00 00</attrib>
    <attrib>01 00</attrib>
    <attrib>02 00</attrib>
    <attrib>03 00</attrib>
  </ClusterId>
  <ClusterId id=""00 00"">
    <attrib>00 00</attrib>
    <attrib>04 00</attrib>
    <attrib>05 00</attrib>
    <attrib>07 00</attrib>
  </ClusterId>
  <ClusterId id=""07 02"">
   <attrib>00 00</attrib>
    <attrib>00 02</attrib>
    <attrib>00 03</attrib>
    <attrib>03 03</attrib>
    <attrib>06 03</attrib>
  </ClusterId>
</DataDownload >");

         System.Xml.XmlNodeList result = xmlDoc.SelectNodes("//ClusterId[@id='00 15']");

         if (result.Count > 0) {
            // Here you go through the child nodes of the first result (result[0])
         }
