StringRegExp flags

[ffdshow]

I want to find a filename from a registry value after using the regread command; for example:

[HKEY_CURRENT_USER\Software\Classes\http\DefaultIcon]

@="\"C:\\Program Files\\Opera\\Opera.exe\",1"

or

[HKEY_CURRENT_USER\Software\Classes\http\shell\open\command]

@="\"C:\\Program Files\\Internet Explorer\\IEXPLORE.EXE\" -nohome"

or

[HKEY_CURRENT_USER\Software\Classes\http\shell\open\command]

@="\"C:\\Program Files\\Mozilla Firefox\\firefox.exe\" -requestPending -osint -url \"%1\""

So, I want to find the executable filename whatever it may be, but I don't know how to use the flags or delimiters in StringRegExp.

Search for _GetDefaultBrowser() by wakillon, he uses a well constructed SRE.

ffdshow,

This works for the strings you posted:

$sKey = '@=""C:Program FilesOperaOpera.exe",1"'
$sFileName = StringRegExpReplace($sKey, '.*(.*)"[s,].*', "$1")
ConsoleWrite($sFilename & @CRLF)

$sKey = '@=""C:\Program Files\Internet Explorer\IEXPLORE.EXE" -nohome"'
$sFileName = StringRegExpReplace($sKey, '.*(.*)"[s,].*', "$1")
ConsoleWrite($sFilename & @CRLF)

$sKey = '@=""C:Program FilesMozilla Firefoxfirefox.exe" -requestPending -osint -url "%1""'
$sFileName = StringRegExpReplace($sKey, '.*(.*)"[s,].*', "$1")
ConsoleWrite($sFilename & @CRLF)

SRE explanation:

.*    - Characters up to a  (we need to escape  with another  so we need  to match )
(.*)      - Capture the characters until...
"[s,]  - another backslash followed by a " and either a space or a comma (again we need to escape the )
.*        - And then another bunch of characters

$1        - Replace all the above with the captured group

Because SREs are naturally greedy, the initial section goes all the way to the last on its own.

All clear?

Easy way could also be:

#include <array.au3>
;~ $str = '@=""C:\Program Files\Internet Explorer\IEXPLORE.EXE" -nohome"'
;~ $str = '@=""C:Program FilesOperaOpera.exe",1"'
$str = '@=""C:Program FilesMozilla Firefoxfirefox.exe" -requestPending -osint -url "%1""'
$re = StringRegExp($str, '(?i)([^]*.exe)', 3)
_ArrayDisplay($re)

Thanks! Both scripts works fine. This was the hard part.
