Regex - NewLine

[Krish]

Hi,

In our application we need to replace the text \n to \r\n, but few of
our text has \r\n. I am not sure how to handle the case.

for eg; Test\rOneMore\r\n.

I need the output has Test\r\nOneMore\r\n.

I know I can do this using String.Replace method... but I need to use
Regex.

I tried using

String str = "Test\nOneMore\r\n";
Regex rx = new Regex("[^\r]\n",RegexOptions.IgnoreCase |
RegexOptions.Compiled);
str = rx.replace(str, "\r\n");

Output:
Tes\r\nOneMore\r\n. ** "t" from test is missing. I think it is
expected behaviour"

Anyhelp is appreciated.

Thanks,
Krish

Learn some patience. No one here is obliged to help you at all, let alone
within six hours.

It's an area I have not used extensively so I won't try to give you the
precise solution, but I think that you need to look at something called a
"zero width look behind assertion" - or something similar. These are
described under "Grouping Constructs" in msdn documentation:
http://msdn.microsoft.com/en-us/library/bs2twtah.aspx

You may have to look at the MultiLine and SingleLine options too.

If you have to experiment a bit and iterate yourself to the solution you
will find Expresso from Ultrapico (it's free) extremely helpful.

Regex rx1 = new Regex("<BR/?>|(?<!\r)\n", RegexOptions.IgnoreCase |
RegexOptions.Compiled);
