最近做一个项目，要集成N多系统，单点登录和取待办任务，各个系统返回数据格式各不相同，有的是xml,有的是json,即便同样是返回xml或者json,其键值也可能不一样，因此，写了一个通用方法来解析xml和json,下面是代码
/// <summary>
/// 将xml解析成指定格式数据
/// </summary>
/// <param name="xmlstr">xml字符串</param>
/// <param name="xmlpath">xml路径</param>
/// <param name="xmlkey">xml键值</param>
/// <param name="tpath">xml总数路径</param>
/// <returns></returns>
public static TaskModel GetListByXml(string xmlstr,string xmlpath,string xmlkey,string tpath)
{
TaskModel tm = null;
if (string.IsNullOrEmpty(xmlstr)) return null;
XmlNodeList xnl = ConfigHelper.GetXmlNodeListByXmlDoc(xmlstr,xmlpath,null);
if (xnl == null) return null;
if (string.IsNullOrEmpty(xmlkey))
{
return null;
}
string[] colarr = xmlkey.Split('|');
if (colarr.Length != 2) return null;
List<TaskVM> tlist = new List<TaskVM>();
foreach (XmlNode xn in xnl)
{
TaskVM vm = new TaskVM();
XmlNodeList sxnl = xn.ChildNodes;
foreach (XmlNode sxn in sxnl)
{
string name = sxn.Name;
//string lname = sxn.LocalName;
if (colarr[0] == name)
{
vm.TaskName = sxn.InnerText;
continue;
}
if (colarr[1] == name)
{
vm.FqTime = sxn.InnerText;
continue;
}
}
tlist.Add(vm);
}
int tasknum = 0;
XmlNode txn = ConfigHelper.GetSingleXmlNodeByXmlDoc(xmlstr,tpath);
if (txn != null && ValidHelper.IsIntData(txn.InnerText))
{
tasknum = Convert.ToInt32(txn.InnerText);
}
if (tm == null) tm = new TaskModel();
tm.TaskList = tlist;
tm.Total = tasknum==0?tlist.Count:tasknum;
return tm;
}

public static TaskModel GetListByJson(string xmlstr,string tpath)
{
TaskModel tm = null;
if (string.IsNullOrEmpty(xmlstr)) return null;
string[] keycol = xmlpath.Split(new string[]{"/"},StringSplitOptions.RemoveEmptyEntries);

{

{

if (index >= keycol.Length)

//数据肯定是Jarray

{

foreach (JProperty jp in jobj)
{

{

}

if (tm == null) tm = new TaskModel();
tm.TaskList = tlist;

return tm;
}
其中xmlpath值就是相对于根的路径，xml的xmlpath就不说了，jsonpath,这里暂且这样叫吧，也按照数据相对于根的地址写，不同级的键，用/隔开就行。
xmlkey就是要取的键值，比如json的数据列表键值为：items,其中对应的标题键是Title,时间是date,xmlkey就写成：Title|date
tpath是取记录总数的路径
