Question
How can I delete a tag and add a new one after a certain tag?
I have this html example.
<p class="cs40314EBF"><span class="cs1B16EEB5">This is an ordinary text.</span></p>
and this is one potential result.
<p class="cs40314EBF"><b>This is an ordinary text.</b></p>
Here's my code.
HtmlDocument doc = new HtmlDocument();
doc.Load(htmlLocation);
foreach (var item in doc.DocumentNode.Descendants())
{
if (item.Name == "span")
{
HtmlNode div = doc.CreateElement("b");
//what do i need to do here?
}
}
I looked into it and discovered this
http://www.nudoq.org/#!/Packages/HtmlAgilityPack/HtmlAgilityPack/HtmlNode/M/InsertBefore
I can't, however, get it to function.
I am unable to
if (item.Name == "span")
{
item.Name = "newtag";
}
because I need the class value. to choose the tag I'm going to use
Accepted Answer
Please review the code below; you must setInnerHtml
and invoke the save function to save the HTML content.doc.Save(yourfilepath)
.
if (item.Name == "span")
{
HtmlNode div = doc.CreateElement("b");
div.InnerHtml = "Hello world";
item.AppendChild(div);
doc.Save(yourfilepath);
}

Can you give it a try?
var doc1 = new HtmlAgilityPack.HtmlDocument();
doc1.LoadHtml("<p class=\"cs40314EBF\"><span class=\"cs1B16EEB5\">This is an ordinary text.</span></p>");
foreach (var item in doc1.DocumentNode.Descendants())
{
if (item.Name == "span")
{
HtmlNode b = doc.CreateElement("b");
b.InnerHtml = item.InnerText;
item.ParentNode.AppendChild(b);
item.Remove();
}
}
