StringRegExReplace

15 posts in this topic

Hello,

i have a huge amount of data to process. My goal is it to turn this

This is a text @1234@ seperated by some @7890@ strange looking @8755@ constructions.

into this

This is a text @1@ seperated by some @2@ strange looking @3@ constructions.

I am able to replace the @####@ data with this piece of code:

$sString = "This is a text @1234@ seperated by some @7890@ strange looking @8755@ constructions."
$sResult = StringRegExpReplace($sString, "@[0-9]{4}@", "\n", 0)

Is there anyway to achieve my goal using StringRegExReplace?

Thanks for some hints.

HurleyShanabarger,

Welcome to the AutoIt forums. :)

I fear you may have to do some additional processing: :(

#include <StringConstants.au3>

$sString = "This is a text @1234@ seperated by some @7890@ strange looking @8755@ constructions."

; Replace all instances of "@nnnnn@" with a single unique string
$sReplaced = StringRegExpReplace($sString, "@[0-9]{4}@", "@#####@", 0)

; Split the string on that unique string
$aSplit = StringSplit($sReplaced, "@#####@", $STR_ENTIRESPLIT)

; Reconstruct the string adding the increasing count value
$sResult = ""
For $i = 1 To $aSplit[0] - 1
    $sResult &= $aSplit[$i] & "@" & $i & "@"
Next
$sResult &= $aSplit[$i]

ConsoleWrite($sResult & @CRLF)
But no doubt some RegEx guru will be along in a minute to show us mere mortals how it can be done. :D

The specification is ambiguous. Do you want to replace successive occurrences of @dddd@ by successive values @1@, @2@, @3@, ... like mikell did

or do you pick digits from the first occurrence for replacement?

In other words, what should be the outcome of:

This is a text @6543@ seperated by some @7890@ strange looking @8755@ constructions.

This?

This is a text @1@ seperated by some @2@ strange looking @3@ constructions.

That?

This is a text @6@ seperated by some @5@ strange looking @4@ constructions.

Also,

Does a "@" always delimit the chars you want to replace?

Is the replaced pattern always 4 digits?

edit:

A real life example (sample of your file) might b helpful.

Hi there,

the solution of mikell is exactly what I need. Thanks a lot, mate.

I am sorry, that the description was not very clear.

The speed is also awesome - exactly what I needed!

Hey guys,

I got another one for you. The data that I want to examine now is build similar like this:

<field XXXXXXX>Text<More nested stuff></field><field YYYYYY>test</field>

What i want to retrieve now is this:

[0] = <field XXXXXXX>Text<More nested stuff></field>
[1] = <field YYYYYY>test</field>

I tried it with this piece of code, but that is not helping me:

$_l_sString = '<field XXXXXXX>Text<More nested stuff></field><field YYYYYY>test</field>'
$_l_aResult = StringRegExp($_l_sString , "(?<=\<field)(.*)(?=\<\/field>)", 1)

Any hints for me?

Thanks again!

That?

#include <Array.au3>

$_l_sString = '<field XXXXXXX>Text<More nested stuff></field><field YYYYYY>test</field>'
$_l_aResult = StringRegExp($_l_sString , "(<field.*?/field>)", 3)
_ArrayDisplay($_l_aResult)

@Mikell : the OP said i have a huge amount of data to process, so maybe it's possible to have more than 999 replacements. In this case, your code won't work properly. :laser:

But Melba's code will do the job perfectly. :P

Sorry for the joke ... Just add a replacement to avoid this (a mix of Melba's and Mikell's code):

$sString = "This is a text @1234@ seperated by some @7890@ strange looking @8755@ constructions."

$n = 0
While 1
    $n += 1
    $sString = StringRegExpReplace($sString, "(?<=@)\d{4}(?=@)", "#" & $n & "#", 1)
    If @extended = 0 Then Exitloop
Wend
$sString = StringRegExpReplace($sString, "@#(\d+)#@", "@$1@")

Msgbox(0,"", $sString)

I tried to launch the replacement with my code with a file containing 10000 lines : it's very slow :(

With this following code, it's really faster (just one global remplacement and one Execute) :

$sString = "This is a text @1234@ seperated by some @7890@ strange looking @8755@ constructions."

$sOutput = "'" & StringReplace($sString, "'", "''") & "'"
$sOutput = Execute ( StringRegExpReplace($sOutput  , "(?<=@)\d+(?=@)", "' & Assign(""iReplace"", Eval(""iReplace"") + 1) * 0 + Eval(""iReplace"") & '") )
MsgBox(0, "", $sOutput)

I doubt I'm at the root of Execute(StringRegexp...), in AutoIt ot whatever other language. We just borrow/inherit from piles of geniuses.
