</table>

推荐答案
Html Agility Pack构造了一个读/写DOM,因此您可以按自己的方式对其进行重建.这是一个似乎可行的示例代码:
The Html Agility Pack constructs a Read/Write DOM, so you can rebuild it the way you want. Here is a sample code that seems to work:
HtmlDocument doc = new HtmlDocument();
doc.Load("MyTest.htm");
// get the first TR
CloneAsParentNode(doc.DocumentNode.SelectNodes("table/tr[1]"), "thead");
// get all remaining TRs but the last
CloneAsParentNode(doc.DocumentNode.SelectNodes("table/tr[position()<last()]"), "tbody");
// get the first TR (it's also the last, since it's the only one at that level)
CloneAsParentNode(doc.DocumentNode.SelectNodes("table/tr[1]"), "tfoot");
static HtmlNode CloneAsParentNode(HtmlNodeCollection nodes, string name)
{
HtmlNode parent = nodes[0].ParentNode;
// create a new parent with the given name
HtmlNode newParent = nodes[0].OwnerDocument.CreateElement(name);
// insert before the first node in the selection
parent.InsertBefore(newParent, nodes[0]);
// clone all sub nodes
foreach (HtmlNode node in nodes)
{
HtmlNode clone = node.CloneNode(true);
newParent.AppendChild(clone);
}
// remove all sub nodes
foreach (HtmlNode node in nodes)
{
parent.RemoveChild(node);
}
return newParent;
}
