Regular Expression Help

Recommended Posts

gruntydatsun

Could someone please help with an regular expression?

I have a large string with lots of folder paths created using dir output sent to a variable.

There are no files in the listing, only folders.

Each path is on it's own line and terminated with @CRLF.

An example of one of the lines would be:

\\server\folder\folder\folder\folder\FOLDEr Site Name Etc

I need to extract paths from the string where:

* the last foldername starts with at least four capital letters

I am nine-tenths of the way to a regex-related rage-quit brain hemmorage. Please help.

I would first split the string and loop through the array like this.

#include <Array.au3> ; For array display purpooses

$sStringData = "serverfolderfolderfolderfolderFOLDEr Site Name Etc" & @CRLF & _
"serverfolderfolderfolderfolderfolder Site Name Etc" & @CRLF & _
"blah blah blah" & @CRLF & _
"serverfolderfolderfolderfolderFOLDEr Site Name Etc"

$aArray = StringSplit($sStringData, @CRLF, 1)
_ArrayDisplay($aArray) ; Test

For $i = 1 To $aArray[0]
    If StringRegExp($aArray[$i], "([A-Z])") Then MsgBox(0, "Match found", "Array Element " &$i)
Next

This is the simple solution. You could also build a more complicated regexp to create an array of matches in one hit. I don't really have a lot of time right now so perhaps someone else can assist you further.

gruntydatsun,

This works for me: :)

#include <Array.au3> ; For array display purpooses

$sStringData = "serverfolderfolderfolderfolderFOLDEr Site Name Etc" & @CRLF & _
                "serverfolderfolderfolderfolderfolder Site Name Etc" & @CRLF & _
                "blah blah blah" & @CRLF & _
                "serverfolderfolderfolderfolder2FOLDEr2 Site Name Etc"

$aRet = StringRegExp($sStringData, "(.*[[:upper:]]{4}.*)(?:z|v)", 3)

_ArrayDisplay($aRet)

And for you? ;)

Melba, you've missed the "at least" part before "4 capital letters".

So make it {4,} <--- Oops, that was pretty dumb (eyes not fully open!)

There is an issue: we still need to comply with the "last" requirement (last foldername).

@OP,

To make that work elegantly, may foldernames contain whitespaces?

Are site name etc optional?

If NO to both, try this:

#include <Array.au3> ; For array display purpooses
$sStringData =  "serverfolderfolderfolderfolderFOLDEr Site Name Etc" & @CRLF & _
    "serverfolderfolderfolderFOLDerfolder Site Name Etc" & @CRLF & _
    "serverfolderfolderfolderFOLDERfolder Site Name Etc" & @CRLF & _
    "serverfolderfolderfolderfolderfolder SITE Name Etc" & @CRLF & _
    "serverfolderfolderfolderfolderfolder WITH Site NAME Etc" & @CRLF & _
    "serverfolderfolderfolderfolderfolder WITH Site NAME Etc" & @CRLF & _
    "blah blah blah" & @CRLF & _
    "serverfolderfolderfolderfolder2FOLDEr2 Site Name Etc"
$aRet = StringRegExp($sStringData, "(.*[[:upper:]]{4,}[^s]*)s[^]*", 3)
_ArrayDisplay($aRet)
