how to allow all data- attributes about htmlsanitizer

[mganss]

This was at a time when we still used CsQuery, so it no longer works with AngleSharp which is what we are currently using. Now you can just use the AllowDataAttributes property:

sanitizer.AllowDataAttributes = true;

Yes. Data attributes are by default removed, this will allow them:

var sanitizer = new HtmlSanitizer();
sanitizer.RemovingAttribute += (s, e) => e.Cancel = e.Attribute.Key.StartsWith("data-");

Hello @mganss.
I came across this thread because I was looking into how to enable data-* attributes.
I tried this

sanitizer.RemovingAttribute += (s, e) => e.Cancel = e.Attribute.Key.StartsWith("data-");

But am getting an error saying:

Error CS1061 'IAttr' does not contain a definition for 'Key' and no accessible extension method 'Key' accepting a first argument of type 'IAttr' could be found (are you missing a using directive or an assembly reference?)

I looked into IAttr's definition and there is not a Key property, but there is Name.

Will this achieve the same results?

sanitizer.RemovingAttribute += (s, e) => e.Cancel = e.Attribute.Name.StartsWith("data-");

For anyone who might run into this:
Just tested it and it does work.
