StringRegExpReplace Help!!??

9 posts in this topic

#1 ·  Posted (edited)

I am needing to remove everything that is not a letter, number, non-breaking space or / or . or ? or : or -

I am trying this,

$result = StringRegExpReplace($string, "[^[:word:][:blank:]/.?:-]", "")

But not working. I am still getting all kinds of stuff like "@÷XÉ€ @·RÒð»3”%€ð‘ŽF" left in the string.

??

I could also use some assistance or pointers on replacing "/something.ext" with "/something.ext-cut-" so that I can trim after the extension in a url.

It would help immensly if you would post a couple of example strings and what you expect to be returned.

The strings should be complete lines that contain the urls.

Some of the lines I am trying to pull urls and text-only from cause problems when posting, but I will try...

Line would look like :

"®•mÁÖÌÅ`h”3@¼}3@¼}ï¾­Þres://ieframe.dll/background_gradient.jpg­Þbackground_gradient[2]Þï¾­Þï¾­Þï¾­Þï¾­Þï¾­Þï¾­Þï¾­Þï¾­Þï¾­Þï¾­Þï¾­Þï¾­Þï¾­Þï¾­Þï¾­Þï¾­Þï¾­Þï¾­Þï¾­Þï¾­Þï¾­ÞREDR€ˆ€­T2http://servername/Sumtotal/lang-en/management/registrationex/LMS_Registration_Post.aspae9ddabd­Þï¾­Þï¾­"

I want to pull "res://ieframe.dll/background_gradient.jpg" and "http://servername/Sumtotal/lang-en/management/registrationex/LMS_Registration_Post.asp" out of that line.

To trim the "_Post.aspae9ddabd­" down to just "_Post.asp" , I was hoping for something like :

$url = StringRegExpReplace($url, "/w*.[:alpha:]{0,4}", "$1-cut-")
$cut = stringinstr($url,"-cut-",1)
$len = stringlen($url)
$url = stringtrimright($url,$len-$cut)

Not that it is working as I would expect from reading the "help" file, but also, I could see having to put something to match .asp or .aspx or .html or .htm or .js or on and on...

EDIT:

$url = StringRegExpReplace($string, "(.)(jpg|gif|asp|htm|html|aspx|js|java|php|xhtml|xml|png)", "$1$2" & "-cut-")

Seems to be working fine for doing that. :)

Thank you! That is working better than :

$url = StringRegExpReplace($url,"[^[:word:][:blank:]/.?:-]f", "")

If you want to grep blanks too then you can replace

a-zA-Z0-9

Or if you don't want the blanks you can use [:alnum:]

If you look in my sig there is a toolkit that will allow you to load a web page as html and test against it.

Is it me or do the urls have a character encoding issue? I suspect it would be safer to solve that root cause instead.

Is it me or do the urls have a character encoding issue? I suspect it would be safer to solve that root cause instead.

Quite possibly.

The whole script is finding the index.dat file in Temporary Internet Files and trying to pull the info from there.

I have it working fairly well, but I know its getting a LOT of info, but not pulling all the urls from the file and it is giving me some blank entries - even though I have

If StringInStr($ln, "://") And StringLen($ln) > 6 Then

before returning the entry. So, the entry has "://" and is longer than six characters, but its displaying in msgbox and reports (csv) as blank??

I haven't even tried for getting the time stamps...

It is eventually going to be a function in another script, but if anyone wants to play with index.dat and getting info from it, here is what I've got so far.

; Some sample remote IE History locations
;
;ThatComputerc$UsersSomeUserAppDataLocalMicrosoftWindowsTemporary Internet FilesContent.IE5index.dat
;TheOtherPuterc$Documents and SettingsSomeUserLocal SettingsTemporary Internet FilesContent.IE5index.dat
;
;Registry keys of use
;
;HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindowsCurrentVersionExplorerShell Folders - gives all user folders
;HKEY_USERS.DEFAULTSoftwareMicrosoftWindowsCurrentVersionExplorerUser Shell Folders - gives the paths for user folders
#include <Array.au3>
$strComputer = @ComputerName
$user = @UserName
; the User Name for the folder may have the domain attached to it in some rare cases, ie "UserName.mybiz"
Global $logfile = FileOpen("Report.csv", 2)
$rprefix = "" & $strComputer & ""
$ProfilesPath = RegRead($rprefix & "HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindowsCurrentVersionExplorerShell Folders", "Common Documents")
; This gives something like C:UsersPublicDocuments or C:Documents and SettingsAll UsersDocuments - we just want the first part.
; So, find the second "" and remove everything after that
$2slash = StringInStr($ProfilesPath, "", 0, 2)
$len = StringLen($ProfilesPath)
$ProfilesPath = StringTrimRight($ProfilesPath, $len - $2slash)
$ProfilesPath = StringReplace($ProfilesPath, ":", "$")
; get the IE history folder path
$historypath = RegRead($rprefix & "HKEY_USERS.DEFAULTSoftwareMicrosoftWindowsCurrentVersionExplorerUser Shell Folders", "Cache")
; This gives us something like %USERPROFILE%AppDataLocalMicrosoftWindowsTemporary Internet Files or
; %USERPROFILE%Local SettingsTemporary Internet Files
; Strip out the %USERPROFILE% and we're in business!
$historypath = StringReplace($historypath, "%USERPROFILE%", "")
$indexdatpath = $rprefix & $ProfilesPath & $user & $historypath & "content.ie5index.dat"
$test = FileExists($indexdatpath)
;MsgBox(0,"Index.dat Path",$indexdatpath & @CRLF & $test)
_ParseIndexdat($indexdatpath)
;_OBOD_ParseIndexdat($indexdatpath)
FileClose($logfile)
Exit

Func _ParseIndexdat($indexdatpath)
; Parse index.dat file for useable info
; The tools I've seen don't grab all the info I want :(
$Bindexdat = FileOpen($indexdatpath, 16)
$indexdat = FileRead($Bindexdat);$indexdatpath)
