ASP.NET/VB/REGEX: Two New Lines or Carriage Returns in a Row

I use this REGEX to identify two lines in a row:
(\r\n\r\n)

Open in new window

I use it in this context:
input = RegularExpressions.Regex.Replace(input, "(?=.{1,999}\n)([\S\S]*(?:(?: [!\S!\S]+)*)?)(\r\n\r\n)", "<strong class=""top"">$1 ...</strong>" + VbNewLine )

Open in new window


The problem is that if the data was input using some operating systems that REGEX does not work.

How can I identify two new lines lines or carriage returns in a row regardless of the OS?

Do you have an example of the output from the other OS?

It does not apply the strong tag from the other OS.

What is the "other OS"? What is the input?
This is the best money I have ever spent. I cannot not tell you how many times these folks have saved my bacon. I learn so much from the contributors.

My question is this:


(\r\n\r\n)

Instead of that, what can I do to detect two new lines in a row OR two Carriage Returns in a row?
