Hello @yuejunhi ,

This is by purpose since closing is invalid in HTML 5. See the following answer: https://stackoverflow.com/a/54412209

If you wish, we could check if that's possible to add an option to force the "close" which I believe will make sense for many people.

Just let us know if you need this option or not.

Best Regards,

Jon

Hello @JonathanMagnan ,

If you can add an option to force the "close",please like "<img src="123.jpg"/>".

Hello @yuejunhi ,

Look like we already have this options. See the following example:

HtmlDocument htmlDocument = new HtmlDocument();
htmlDocument.OptionWriteEmptyNodes = true;
htmlDocument.LoadHtml(@"<div><img src=""123.jpg"" />");
var test = htmlDocument.DocumentNode.OuterHtml;

Let me know if that's what you were looking for.

Hello @JonathanMagnan ,

Could you override the method of “HtmlNode.CreateNode(string html)” ，like "HtmlNode.CreateNode(string html, bool OptionWriteEmptyNodes)”？
Let me set htmlDocument.OptionWriteEmpty value equal true or false！

Oh I see,

I copied the code from my developer but that doesn't fit 100% for your requirement.

Sure, we will look at it.

Hello @JonathanMagnan ,

Please see the following example:
HtmlNode node = HtmlNode.CreateNode("<img src="123.jpg" />");
string htmlStr = node.OuterHtml;
The result "htmlStr",we want , is equal "<img src="123.jpg"/>",
but we get "<img src="123.jpg">" ,lose "/";

Hello @yuejunhi ,

The v1.11.31 has been released.

It's now possible to pass a builder to choose some options such as OptionWriteEmptyNodes

Here is an example:

HtmlNode node2 = HtmlNode.CreateNode(@"<img src=""123.jpg"" />", options => options.OptionWriteEmptyNodes = true);

Let me know if you successfully implemented the solution.

Best Regards,

Jon
