string xpath = "/Field/FieldName[@FieldName='X']";
doc.GetElement(xpath )[0];

学学xpath（一般的定位最少要学会这个）或xquery吧
对xml操作很牛

foreach (var q in query)

最外面加一层/root
XmlDocument xmldoc=new XmlDocument （）；
xmldoc.Load("");//加载xml，""中为xml文档的路径，或者如一楼的将xml文档定义成string xml
加载就得写成xml.LoadXml(xml);
XmlNode xmlnode=xml.SelectSingleNode("/root");
XmlNodeList xnlNodelist=xmlnode.ChildNodes;
foreach(XmlNode item in xmlNodelist)
{
XmlNode xn=item.FirstChild;
string nodeValue=xn.InnerText;
}

你给的格式不正确吧，外面好像应该还有一层，根节点不能是多个
