Как я уже сказал, у меня есть набор узлов XML, каждый узел имеет атрибут ows_ID, теперь я хочу найти узел с максимальным идентификатором ows_ID.

Хорошо, я бы использовал LINQ to XML и, вероятно, MaxBy из MoreLINQ : 

XElement doc = XElement.Load(...); // Insert your filename or whatever here
XNamespace z = "#RowsetSchema";
XElement max = doc.Descendants(z + "row")
                  .MaxBy(x => (int) x.Attribute("ows_ID"));

В качестве альтернативы, без MoreLINQ: 

XElement doc = XElement.Load(...); // Insert your filename or whatever here
XNamespace z = "#RowsetSchema";
int maxId = doc.Descendants(z + "row")
               .Max(x => (int) x.Attribute("ows_ID"));
XElement max = doc.Descendants(z + "row")
                  .First(x => (int) x.Attribute("ows_ID") == maxId);

Может быть, это поможет: 

XElement element = XElement.Load("Your.xml");
int max = element.Elements("Element").Max(l => int.Parse(l.Attribute("ItemId").Value));
XmlNode node = xmlDocument.SelectSingleNode("Element[@ItemId='" + max+"']");
...
