StringRegExp Help

[ken82m]

I suck at this can someone please help me with this.

I just want to check the format of something to see if it is a properly formatted IP address.

so it should be xxx.xxx.xxx

each x has to be a number

and each section can be 1-3 numbers

Here's my poor attempt lol

$1 = "1.1.1.1"
$1 = StringRegExp("1.1.1.1", "[:digit:]/x00")
MsgBox(0,"is ip", $1)

Thanks,

Kenny

Check the list on the bottom, some nice patterns for known decimal inputs like IPv4 etc..

Edit: I see it's IPv4 pattern is broken so here it's anyway, fail faster in my opinion:

^(?>(?:\d|[01]?\d\d|25[0-5]|2[0-4]\d)\.){3}(?:\d|[01]?\d\d|25[0-5]|2[0-4]\d)$'

thanks for the string, and the site.

Wouldn't happen to know one to help me build one would you?

Here is another regexp that I think will do what you want. I could be wrong though. That happened once before.

"(\d{1,3}\.\d{1,3}\.\d{1,3}\.\d{1,3})"

It can match for sure, anything from "0.0.0.0somthinglong" to "999.999.999.999Somethingevenlonger...0.0.0.999999999and this"

That makes twice now (that I've been wrong).

Edit. Oooops, forgot to mention that I was talking about twice within a 3 minute time span.

GEOSoft, technically you're correct in looking for 4 1-3-digit pairs, but if you need to make sure it doesn't include any other characters in the string, you can just add the start-of-string and end-of-string characters to each side like this:

^(\d{1,3}\.\d{1,3}\.\d{1,3}\.\d{1,3})$

Of course, they are right about invalid IP addresses.. I really don't know the correct range of #'s myself

[Authenticity]

You don't need to care if this IP address exists as you may want to make sure it's first in the range 0-255 in all the fields, it's also true that 0.0.0.0 certainly does not exist as 255.255.255.255 for that matter neither. The rest of the check is using a data base or calling ping.

[GEOSoft]

It actually could be handled with a stringsplit too. Then just check that the number in each element is between 0 and 255. SmOke_Ns solution works. Just difficult to read with the AutoIt tags and smileys enabled.

This should work as well, not much different I'm sure from what I've posted before in the link provided:

Local $s_text = ClipGet()

Local $s_pattern = "((?:(?:[0-1][0-9]{2}|2[0-4][0-9]|25[0-5]|[0-9]){1,2}\.){3}" & _
                    "(?:[0-1][0-9]{2}|2[0-4][0-9]|25[0-5]|[0-9]))"

Local $a_sre = StringRegExp($s_text, $s_pattern, 3)
