REGEX question

I'm very new to Regex, I've been strugling a lot to use it, hard to
find good material :)

I just need to find all matchs for something like this:
D00:00:00:00

leter D, following by 4 sequences of 2 digits separated by : (2
points)

How can I do that?

There is any software for windows that helps us newbies learn that
fabulous language?


Thanks!!

"D[0-9]{2}:[0-9]{2}:[0-9]{2}:[0-9]{2}"

A while back I used the .Net Regex Workbench. Can't seem to find a place
to download it from now though...

Him Tim, Thanks!

Thats wierd, your code works on my pspad regex search (if found a
example I type in my source-code), but when I run over php, this error
is returned:

Warning: preg_match_all() [function.preg-match-all]: Delimiter must
not be alphanumeric or backslash

You know why?

If you use the preg_* family, you have to use delimiters (any
non-alphanumeric character that's not the backslash) to surround your
pattern, so you can put modifiers behind the ending delimiter if you like.
'/' is the most commonly used.

preg_match_all('/D[0-9]{2}:[0-9]{2}:[0-9]{2}:[0-9]{2}/',$string,$matches);

Rik posted the answer to this, but I'd like to take this opportunity to put
in a recommendation for an excellent and somewhat underappreciated book:
Jeffrey Friedl's "Mastering Regular Expressions".

I got the book originally on a whim, thinking "what could he possibly have
to say about regular expressions that would take a whole book", but I find
that I have referred to it again and again. It is an excellent and
thorough treatise on the subject. The third edition even includes a
45-page chapter on PHP.

And as a bonus, he includes a regular expression that matches every legal
RFC 822 email address. It is several tens of thousands of characters long.
