让我把场景： 如果学生＆＃39;节点具有相同的子元素，然后合并学生＆＃39;节点。在这种情况下，如果姓名＆＃39;节点可以在其他“学生”中找到具有相同值的节点然后是那些2＆＃39;学生＆＃39;节点需要与唯一元素合并。在这种情况下，＆＃39;名称＆＃39;节点相同来一次和地址＆＃39;节点来了2次。 此外，输入xml可以具有不同的子节点集，并且每次都可以具有不同的名称。 下面是输入xml

我尝试使用以下代码实现。我知道它效率不高。
var newdoc = XDocument.Parse(input);
// 'restriction' is the concerned node
foreach (var element in newdoc.Descendants("restriction"))
{
if (skiptimes > 0)
{
skiptimes--;
continue;
}
//Get distinct node names for 'element'
var distinctNodeName = element.Elements().Select(cc => cc.Name).Distinct();
//delete if found 'freetext' node as the this do not need to be comapared
distinctNodeName = distinctNodeName.Where(n => n.LocalName.ToString() != "FreeText");
//Get distinct elements
var distinctElementName = element.Elements().Select(xx => xx).Distinct();
foreach (var nextelement in element.ElementsAfterSelf())
{
if (!nextelement.IsEmpty)
{
//Get distinct node names for 'nextelement'
var distinctNodeName2 = nextelement.Elements().Select(xx => xx.Name).Distinct();
//delete if found 'freetext' node as the this do not need to be comapared
distinctNodeName2 = distinctNodeName2.Where(n => n.LocalName.ToString() != "FreeText");
//Get distinct elements
var distinctElements2 = nextelement.Elements().Select(xx => xx).Distinct();
//From 'element' excluding the 'StopoverSegs' node which by default always come as last node
var subelements = element.Elements().Take(distinctNodeName.Count() - 1);
//From 'nextelement' excluding the 'StopoverSegs' node which by default always come as last node
var sub2 = nextelement.Elements().Take(distinctNodeName2.Count() - 1);
// Compare node name counts which are selected as distinct
if (distinctNodeName.Count() == distinctNodeName2.Count())
{
ArrayList fir = new ArrayList();
int arrcount = 0; ArrayList sec = new ArrayList();
//Add 'element' to array list for comparison
foreach (var firstSet in subelements)
{
fir.Add(firstSet.ToString()); arrcount++;
}
//Add 'nextelement' to array list for comparison
foreach (var secondSet in sub2)
{
sec.Add(secondSet.ToString());
}
//comparison . I could not get through to compare via SequenceEqual or other custom
//extension
for (int i = 0; i < arrcount; i++)
{
if (fir[i].ToString().Trim() != sec[i].ToString().Trim())
{
GotEqual = false;
break;
}
else
{
GotEqual = true;
}

这是一个可怕的代码，我没有时间来清理它，但这很有效。
