我想在div结束后直接插入一些自己的html.这个div里面还有其他div. Dim HtmlNode As HtmlNode = HtmlNode.CreateNode("span class=""label""Those were the friends/span") Dim FriendDiv = htmldoc.DocumentNode.SelectSingleNode("//
Dim HtmlNode As HtmlNode = HtmlNode.CreateNode("<span class=""label"">Those were the friends</span>")
Dim FriendDiv = htmldoc.DocumentNode.SelectSingleNode("//div[@class='profile_friends']")
Dim NewHTML As HtmlNode = htmldoc.DocumentNode.InsertAfter(HtmlNode, FriendDiv)
每次运行该代码时,我都会收到异常节点“< div class =”profile_topfriends“>< / div>”没有在该系列中找到
与XmlNode‘s InsertAfter()类似,您需要在引用节点的公共父节点上调用此方法并插入节点.尝试这样的事情：
Dim NewHTML As HtmlNode = FriendDiv.ParentNode.InsertAfter(HtmlNode, FriendDiv)
为我工作得很好.这是我在C#中做的一个简单的测试(翻译成VB)：
Dim html = "<body><div></div></body>"
Dim doc As New HtmlDocument()
doc.LoadHtml(html)
Dim div = doc.DocumentNode.SelectSingleNode("//div")
Dim span = HtmlNode.CreateNode("<span class=""label"">Those were the friends</span>")
Dim newHtml = div.ParentNode.InsertAfter(span, div)
Console.WriteLine(XDocument.Parse(doc.DocumentNode.OuterHtml).ToString())
< span>出现在< div>之后在控制台.
