Help with "StringRegExp" function

[Sam137]

Hi Guys

Can you please help me out with the pattern of the one which is below:

Pattern to look:

"filepath = "

There are 16 spaces between "filepath" and "= "

If StringRegExp($sStr, "(?im)^(filepathh*=h*[^v]+)") Then
    $sNewStr = StringRegExpReplace($sStr, "(?im)^(filepath)(h*=h*)([^v]+)", "$1$2" & _
      StringRegExpReplace("C:Multi DDt Delete Encounter MPIcleanup.in", "()", ""))

$sStr is the file which is returned from the Fileread command.

I Just want to know how the code the pattern.

Do you know "StringStripWS()"?

[jchd]

StringStripWS will remove WS from inside the path as well, I'm afraid.

@Sam137,

What does you input exactly look like and what do you expect as output, precisely?

[Sam137]

Okay well,

I am searching for the below string in the file.

"filepath****************= "

If this is found then i want to replace it with:

"filepath****************= C:Multi DDt Delete Encounter MPIcleanup.in"

NOTE: Please consider all * as spaces. For that i have the below coding. But its not working.

If StringRegExp($sStr, "(?im)^(filepathh*=h*[^v]+)") Then
    $sNewStr = StringRegExpReplace($sStr, "(?im)^(filepath)(h*=h*)([^v]+)", "$1$2" & _
      StringRegExpReplace("C:Multi DDt Delete Encounter MPIcleanup.in", "()", ""))

[funkey]

OK, and why not use StringReplace only?

[Sam137]

Well I can use String Replace, but the problem is :

Actual whole string in the file is: "filepath****************= e:autitMulti Encounter MPIcleanup.in"

First thing i want to search for the string:

"filepath****************= " Remember * as spaces and then i delete the remaining part of the string i.e."e:autitMulti Encounter MPIcleanup.in" then i replace with "filepath****************= C:Multi DDt Delete Encounter MPIcleanup.in". I think it will be a tedious job in string Replace. Any suggestions?

[funkey]

Maybe I don't understand your problem right, but why not

StringReplace($sStr, "e:autitMulti Encounter MPIcleanup.in", "C:Multi DDt Delete Encounter MPIcleanup.in")

??

[Sam137]

"e:autitMulti Encounter MPIcleanup.in" is not consistent with all the files it keeps on changing, the only thing which is consistent is :

"filepath****************="

sam137,

You are not defining your requirements logically or consistently. Give an example of 10+ filenames and what you need to change them to.

Edit: spelling

Ok, my requirement is:

I have a folder which contains 'n' number of files. I want to open the first file and search for the string "filepath****************= " Remember * as spaces and then i delete the remaining part of the string i.e."e:\autitMulti\ Encounter MPI\cleanup.in" , after deleting the second fragment we have only left with "filepath****************= " then i replace with "filepath****************= C:\Multi DDt Delete Encounter MPI\cleanup.in".

See an example of the file in the attachment.

Example.txt

[jchd]

Does this work as you expect?

Local $text = FileRead("Example.txt")
Local $newtext = StringRegExpReplace($text, "(?im)(^s*filepath[^=]*=)(.*)", "$1C:Multi DDt Delete Encounter MPIcleanup.in")
ConsoleWrite($newtext & @LF)
Local $hdl = FileOpen("Changed.txt", 2)
FileWrite($hdl, $newtext)
FileClose($hdl)

I tried code from jchd and I discovered it needs doubled to work correctly:

Local $newtext = StringRegExpReplace($text, "(?im)(^s*filepath[^=]*=)(.*)", "$1C:Multi DDt Delete Encounter MPIcleanup.in")

I believe the script in post #1 works perfectly.

If the file being read (with FileRead()) is not in the same directory or folder as the script that you are using then the full path of the file to be read (or a path relative to the script) should be used in the FileRead() function.

Because I had the test ".in" file in the same directory as the script this has always worked for me.

See the modified script see if the results returned are as per your requirements.

@Zedna

Sure backslashes need doubling there (reference to captured groups may use $1 or 1 syntax.) They're doubled in my copy. I don't get it how they got de-doubled magically during copy/paste.

jchd,

It is this wonderful "upgraded" editor we now have.

I use it in basic mode all the time - the WYSIWYG version is just too flaky.

Oh shitty modernity.

[Sam137]

@jchd - Thanks for the help.

I like to get the information how to modify it when i have a 2 or more strings to seach and replace with another.

Currently what i have given is to search only for "filepath****************= ". Now i have more strings to search for example "logpath****************= " and "errorpath****************= ". The problem is I dont have a starndard replacement string for all the three.

In one single file:

"filepath****************= " has to be replaced by "C:Multi DDt Delete Encounter MPIcleanup.in"

"logpath****************= " has to be replaced by "D:Testtestup.in"

"errorpath****************= " has to be replaced by "E: Encounter MPItesting.in"

how can i change the below string to cater this.

Local $newtext = StringRegExpReplace($text, "(?im)(^s*filepath[^=]*=)(.*)", "$1C:Multi DDt Delete Encounter MPIcleanup.in")

[funkey]

Last try from my side:

#Include <File.au3>

Global $aFile

_FileReadToArray("Example.txt", $aFile)

For $i = 1 To $aFile[0]
    If StringInStr($aFile[$i], "filepath****************=") Then $aFile[$i] = "filepath****************= C:Multi DDt Delete Encounter MPIcleanup.in"
    If StringInStr($aFile[$i], "logpath****************=") Then $aFile[$i] = "logpath****************= D:Testtestup.in"
    If StringInStr($aFile[$i], "errorpath****************=") Then $aFile[$i] = "errorpath****************= E: Encounter MPItesting.in"
Next

_FileWriteFromArray("Example_new.txt", $aFile, 1)

[Sam137]

But the alignment is getting changed. Its going to the first position. I would want something like in the attacheed file.

Example.txt

That's a standard ini file, are you absolutely 100% sure you need the spaces to remain in the file when it's read by whatever needs to read that file? If not, you can probably just use Iniwrite to rewrite those values, and you won't need any regexp to do it. You might even be able to do it with the spacing, but I don't guarantee that it will keep the spacing.
