Is it possible to remove empty html Tags like


from RTE, because they are getting inserted very easy and destroying the design.

The best would be automaticaly :-) on save or publish.

You can use item:saving event. Be aware that in some cases saving of the item can be intercepted so not necessarily your changes will be saved.

    <event name="item:saving">
      <handler type="My.Assembly.Namespace.RemoveEmptyParagraphsFromRichTextProcessor,
        My.Assembly" method="OnItemSaving" />

and the code

public class RemoveEmptyParagraphsFromRichTextProcessor
    protected void OnItemSaving(object sender, EventArgs args)
        Item newItem = Event.ExtractParameter(args, 0) as Item;

        if (newItem == null || newItem.Database.Name != "master")

        Item originalItem = newItem.Database.GetItem(newItem.ID, newItem.Language, newItem.Version);

        var differences = FindDifferences(newItem, originalItem);

        foreach (var fieldName in differences)
            var value = newItem[fieldName];
            if (!string.IsNullOrEmpty(value))
                newItem[fieldName] = RemoveParagraphWithSpace(value);

    private List<string> FindDifferences(Item newItem, Item originalItem)

        return newItem
            .Where(x => x.Type.Equals("Rich Text"))
            .Select(f => f.Name)
            .Where(fieldName => newItem[fieldName] != originalItem[fieldName])

    private string RemoveParagraphWithSpace(string html)
        // you can be more creative here
        return html.Replace("<p>&nbsp;</p>", "");

    Only thing I would suggest is to consider using HtmlAgilityPack instead of a string replace. Aug 30, 2019 at 18:02

    @MatthewFitzGerald-Chamberlain that's why I used "you can be more creative here" comment. Question was only about removing p tag with space in it. If that's the only requirement then string.replace is much faster. If more complex processing of html is needed, HtmlAgilityPack is the good way. You're right.
