I'm looking for a function that will replace in all content/paragraphs on a given page.
Lets say that every where on the page where there is written "secret" - it should be replace with "urgent".

How can this be done?

I've had a look into both the PageTemplateExtender  and ContentModule with no luck.
Im not interessed in replacing it the actual database - only when it written to the client.

You can use the Standard.Page.AfterOutput notification subscriber:

Imports Dynamicweb
Imports Dynamicweb.Frontend
Imports Dynamicweb.Extensibility


<Subscribe(Dynamicweb.Notifications.Standard.Page.AfterOutput)> _
Public Class NotificationSubscriber1
 Inherits NotificationSubscriber

 Public Overrides Sub OnNotify(ByVal notification As String, ByVal args As Object())
  Dim t As Templatev2.Template = CType(args(0), Templatev2.Template)
  t.Html = t.Html.Replace("Oldstring", "Newstring")
  'TODO: Add code here
 End Sub
End Class

With the newest SR (19.0.3.0) you will be able to use the

Standard.Paragraph.OnBeforeRenderArgs notification to access the ParagraphText field directly.

<Subscribe(Dynamicweb.Notifications.Standard.Paragraph.OnBeforeRender)> _
Public Class NotificationSubscriber2
 Inherits NotificationSubscriber

 Public Overrides Sub OnNotify(ByVal notification As String, ByVal args As NotificationArgs)
  Dim arg As Dynamicweb.Notifications.Standard.Paragraph.OnBeforeRenderArgs = CType(args, Dynamicweb.Notifications.Standard.Paragraph.OnBeforeRenderArgs)
  If Not String.IsNullOrEmpty(arg.Paragraph.Paragraph.ParagraphText) Then
   arg.Paragraph.Paragraph.ParagraphText = arg.Paragraph.Paragraph.ParagraphText.Replace("oldstring", "newstring")
  End If

 End Sub
End Class
