Using CSS - overrule everything.

From management center you can remove editing options from the user - so they cannot use colors, fonts etc.

Hi!

But is it possible to get the user input as clean text, no formatting at all, just the text.

Like <!--@Ecom.Product.ShortDescription.Clean-->

Best regards,

Per

No - not possible...

Hi Per,

You could go wild and use a NotificationSubscriber that responds to OnBeforeRender. Inside the OnNotify method, you can grab the HTML, clean it, and reassign it. Something like the following would give you clean text without any HTML:

using System;
using System.Text.RegularExpressions;
using Dynamicweb.Extensibility;
 
namespace Dynamicweb.Samples.Lib
{
  static class Helpers
  {
    public static string StripHtml(this string html)
    {
      if (html == null) throw new ArgumentNullException("html");
      var re = new Regex(@"<[\/!A-z]+(?:.*?(?:=\s?(?:(""|')[^\1]*\1|[^\s>]*))?)+(?:>|(<))");
      return re.Replace(html, @"${2}");
    }
  }
 
  [Subscribe(Dynamicweb.Notifications.Standard.Paragraph.OnBeforeRender)]
  public class OnBeforeRenderNotificationSubscriber : NotificationSubscriber
  {
    public override void OnNotify(string notification, NotificationArgs args)
    {
      Dynamicweb.Notifications.Standard.Paragraph.OnBeforeRenderArgs myArgs = 
               args as Dynamicweb.Notifications.Standard.Paragraph.OnBeforeRenderArgs;
      myArgs.Paragraph.Paragraph.ParagraphText = myArgs.Paragraph.Paragraph.ParagraphText.StripHtml();
    }
  }
}

Note: this strips away ALL HTML, so may want to alter StripHtml to only remove styling related stuff.

Also note: this fires for each and every request, so may want to build in some if stataements that 
makes this code only run when you really need it.

Hope this helps,

Is it possible to do this using regular expressions in XSLT?

Best regards,

Per

Don't know. Me and XSLT don't mix very well.... ;-)

BTW: you could also create a tag and only render the stripped content when the tag exists:

if (myArgs.template.TagExists("Custom:ParagraphTextClean"))
{
  myArgs.template.SetTemplateValue("Custom:ParagraphTextClean", myArgs.Paragraph.Paragraph.ParagraphText.StripHtml());
}
else
{
  myArgs.template.SetTemplateValue("Custom:ParagraphTextClean", String.Empty);
}

Now, stripping only takes place when your template file contains the tag: Custom:ParagraphTextClean.

Not sure how future proof this is though. The template property is the "old" template object and not 
a TemplateV2 instance. It works fine like this, but it might break in the future.

Hope this helps,

Imar
