Menu
Say I want to remove the span tag from this html:
<html><span>we do like <b>bold</b> stuff</span></html>
I'm expecting this chunk of code to do what I'm after
string html = "<html><span>we do like <b>bold</b> stuff</span></html>";
HtmlDocument doc = new HtmlDocument();
doc.LoadHtml(html);
HtmlNode span = doc.DocumentNode.Descendants("span").First();
span.ParentNode.RemoveChild(span, true); //second parameter is 'keepGrandChildren'
But the output looks like this:
<html> stuff<b>bold</b>we do like </html>
It appears to be reversing the child nodes within the span. Am I doing something wrong?

Looks like a bug in HtmlAgilityPack - see their issue register:

Interestingly this was raised 4 years ago...
Here's a snippet that will remove all span tags (or any other tag you specify) and keeps other nodes in the correct order.
void Main()
{
string html = "<html><span>we do like <b>bold</b> stuff</span></html>";
HtmlDocument doc = new HtmlDocument();
doc.LoadHtml(html);
RemoveTags(doc, "span");
Console.WriteLine(doc.DocumentNode.OuterHtml);
}
public static void RemoveTags(HtmlDocument html, string tagName)
{
var tags = html.DocumentNode.SelectNodes("//" + tagName);
if (tags!=null)
{
foreach (var tag in tags)
{
if (!tag.HasChildNodes)
{
tag.ParentNode.RemoveChild(tag);
continue;
}
for (var i = tag.ChildNodes.Count - 1; i >= 0; i--)
{
var child = tag.ChildNodes[i];
tag.ParentNode.InsertAfter(child, tag);
}
tag.ParentNode.RemoveChild(tag);
}
}
}
