Using StringRegExp

[LocationUnknown]

First of all Hello ,

I'm currently trying to use StringRegExp() to match numbers in a string.

<----- THE DATA ($full) ------>

Memory Processes Infected: 2
Memory Modules Infected: 0
Registry Keys Infected: 1
Registry Values Infected: 0
Registry Data Items Infected: 5
Folders Infected: 100
Files Infected: 3

<----- THE CODE ------>

$memory_num = StringRegExp($full, '(?: *.Processes.*? )([0-9]{1,200})', 2)
$modules_num = StringRegExp($full, '(?: *.Modules.*? )([0-9]{1,200})', 2)
$regkey_num = StringRegExp($full, '(?: *.Keys.*? )([0-9]{1,200})', 2)
$regval_num = StringRegExp($full, '(?: *.Values.*? )([0-9]{1,200})', 2)
$regdata_num = StringRegExp($full, '(?: *.Data.*? )([0-9]{1,200})', 2)
$folders_num = StringRegExp($full, '(?:Folders.*?)([0-9]{1,200})', 2)
$files_num = StringRegExp($full, '(?:Files.*? )([0-9]{1,200})', 2)

I can read single digits fine but when it comes to "Folders Infected: 100". "1" is returned not "100" i have tried using

$folders_num = StringRegExp($full, '(?:Folders.*?): (\d+)', 2)

This still only returns "1"

Can someone please be kind and understanding and explain to me what I'm doing wrong.

Thanks

I think $folders_num[1] will be 100 using StringRegExp($full, '(?:Folders.*?): (\d+)', 2)

Silly me, it was an issue with the way i was feeding the data into $full

Thanks

Are you sure you're wanting to grab as many as 200 decimal digits? (Hint: probably not, and as shown by Martin, \d+ is better in your case.)

Result is an array. Also you don't need the non capturing groups. But now you've got it.

Thanks jchd, i understand that ([0-9]{1,200}) declares a range between 1 - 200. Your right that \d+ is much more suitable in this situation where the value could be just about anything. I realize that StringRegExp generates an array and there is no need for individual variables to be defined . This site helped me out when using regular expression http://regexpal.com/.

Cheers

Yes, 200 ... DIGITS!

A regexp quantifier as {x,y} applied to a metacharacter Z means Z repeated from x times to y times inclusive. So \d{1,200} means a string of at least 1 and up to 200 decimal digits. In general, regexp metacharacters don't look at content, but simply category. There is no interpretation of the successive characters matched or captured as a whole (here as an integer representation). Regexps are fairly formal.
