I like how your user name illustrates the fact that we are all just numbers in a government spreadsheet!

The difficult we do right away...

I had the joy to take my first steps with Regular Expressions today (I have tried to avoid them, but I eventually got that they are absolutely inavoidable, especially when it comes to parsing complex strings).
So I present you my first RegEx:

([0-9]{4})-([1-9]|[1][0-2])-([0-2]?[0-9]|[3][0-1])[T]([0-1]?[0-9]|[2][0-3])[:]([0-5]?[0-9])[:]([0-5]?[0-9])?.?([0-9]{1,6})[Z]([+-][0-9][\.|,]?[0-9]?|[0-9]{2}?|[+-]?[0][1][0-2][\.]?[0-9]?|[0-9]{2}?)

Beautiful, isn't she? Blush | :O

And that's the string it will parse: 2014-2-5T21:36:14.315Z+1.5

Well done!

Get a copy of this: Expresso[^] - it's free, and it explains, tests and helps create regexes. I use it all the time and I wish I'd written it!

Just tried it out - And I hand-crafted my RegEx! Well, learning it from scratch has never caused any damage.

The site OriginalGiff mentioned is very good. Another very helpful site is regexlib[^]; they have a large library of Regular Expressions. They also have a RegEx tester[^].

Just because the code works, it doesn't mean that it is good code.

Thank you. Thank you. Thank you.

I endorse that. Expresso is a very good regex utility.

Strange...I downloaded it here and ran a scan on the MSI and it showed nothing.
So I uploaded it to Dropbox: https://www.dropbox.com/s/3fwe3wtop741hpf/ExpressoSetup3.msi[^] - does that help?

i suppose it's a right of passage everyone has to go through. but whew Smile | :)

me, i avoid regex like the plague. finite state machines are so much easier to understand and maintain.

I had a bit help from an experienced colleague Laugh | :laugh:

The challenge is that it validates a Syslog-Timestamp.

Problem? Yes. Here are some examples of valid timestamps:

2014-2-5T21:36:14.315Z-1.5
2014-2-5T21:36:14Z-1
2004-2-28T21:36:14.315Z+1.75
2004-2-29T21:36:14.315315Z+0

You see the problem Dead | X|

If it was written to some sort of log file by some application, why would you doubt it?

Edit: Now that I have perused the timestamp part of the RFC, I can state, "those are not valid timestamps".

I am probably misinterpreting the RFC 5424 spec that you mentioned below and/or a case of complete RegEx ignorance, but from this site[^] it states that a timestamp can be a NILVALUE (where: NILVALUE = "-"). Do you account for this in your code?

Marco Bertschi5-Feb-14 20:01

5-Feb-14 20:01

You are right - The timestamp can be a NILVALUE!
The RegEx is used within the class SyslogTimestamp (see the discussion [^] why I don't use System.DateTime).
There is another class, called SyslogMessageHeader, which has a field of type SyslogTimestamp.
I plan to handle a NILVALUE as null, and also treat null objects as if they represent a NILVALUE.
