I need to fetch searchResultsRecord node for 50 times

XmlNodeList nodesInfo = responseXml.SelectNodes("./searchResultsList/searchResultsRecord");
foreach (XmlNode result in responseXml.SelectNodes("Payload"))
{
XmlDocument doc1 = new XmlDocument();
result.AppendChild(doc1);
}

My xpath is wrong it seems. How can i get proper xpath after the payload everynode is null.
