StringReplace/StringRegExpReplace function problem

#1 ·  Posted (edited)

Hi coders,
Hi Melba23 :sweating: ,

I have got a string (a href) "index.php?app=core&module=global"
all I need to do is assign php variables to autoit variables like
 

$app = "core"
$module = "global"

To get rid of string parts which I don't need, I tried to use function StringRegExpReplace but I got the following issue (as seen below the code):

StringRegExpReplace($sInput, "index.php?", "")

this should replace "index.php?" with nothing, but there is a logical operator "?" which remains untouched by the function.
 

I didn't find any help about ignoring logical operators so I tried some things and I found that [?] makes ? ignore.

StringRegExpReplace($sInput, "index.php[?]", "")

so this works (the function returns "" (nothing), that's what I need)

Is that the right way to do it, though?

Change your:

index.php?

To:

index.php?

The question mark in regular expression is used for a multitude of special functions. The backslash escapes the question mark in the regular expression and makes the function treat it as a normal character to use in the matching. Check the help for StringRegExp for more information.

knuxfighter,

Welcome to the AutoIt forums - and there is no need to sweat over my presence unless you post something against the rules. ;)

I would do something like this:

$sInput = "index.php?app=core&module=global"

; Extract the "var=value" pairs
$aExtract = StringRegExp($sInput, "(\w*=\w*)", 3)

; Now loop through them
For $i = 0 To UBound($aExtract) - 1
    $sPHP = $aExtract[$i]
    ; Split on the "="
    $aSplit = StringSplit($sPHP, "=")
    ; Construct the new line
    $sAU3 = "$" & $aSplit[1] & ' = "' & $aSplit[2] & '"'
    ; And display it
    ConsoleWrite($sAu3 & @CRLF)
Next
You should see the required lines in the SciTE console. :)

#Include <Array.au3>

$sInput = "index.php?app=core&module=global"

$aExtract = StringRegExp($sInput, "(?:app|module)=(\w*)", 3)
 _ArrayDisplay($aExtract)

Many ways to get the results, depending on their wanted further use

$sInput = "index.php?app=core&module=global"

$aArr = StringRegExp($sInput, "(\w*)=(\w*)", 3)

for $i = 0 to ubound($aArr) - 1 step 2
 assign($aArr[$i] , $aArr[$i + 1] , 2)
next

msgbox (0, '' , "$app = " & eval("app") & @CRLF & "$module = " & eval("module"))

Thank you all a lot for your answers, but this doesn't work if I do it with numbers (include minus numbers, too), I didn't know that one could be so complicated.
btw by the $app etc I mean putting the extracted values into variables for further use and assigning.

$sInput = "index.php?var1=value1&var2=&var3=15&var4=-5"

$aExtract = StringRegExp($sInput, "[?&]([^=]+)=([^&]*)", 3)
For $i = 0 To UBound($aExtract) - 1 Step 2
    ; ConsoleWrite("$" & $aExtract[$i] & "=" & $aExtract[$i + 1] & @CRLF)
    Assign($aExtract[$i], $aExtract[$i + 1])

And again, without the For-Next loop.

Local $sInput = "index.php?var1=value1&var2=&var3=15&var4=-5"

Local $sExtract = Execute("'" & StringRegExpReplace($sInput, ".*?[?&]([^=]+)=([^&]*)", "'&Assign('${1}','${2}')&'") & "'")

ConsoleWrite("$var1=" & $var1 & @CRLF & _
        "$var2=" & $var2 & @CRLF & _
        "$var3=" & $var3 & @CRLF & _
        "$var4=" & $var4 & @CRLF)

....

And with quotes ?

Local $sInput = "index.php?var1='value1'&var2=&var3=15&var4=-5"
:P

 

The following example covers the two possibilities.  The variable value has either double quotes or single quotes.

;Local $sInput = 'index.php?var1="value1"&var2=&var3=15&var4=-5' ; Variable value with double quotes.
;Or
Local $sInput = "index.php?var1='value1'&var2=&var3=15&var4=-5" ; Variable value with single quotes.
;ConsoleWrite($sInput & @LF)

; If the variable value with no quotes, either Execute(string) can be used.
If StringInStr($sInput, '"') Then ; has double quotes
    ;ConsoleWrite("'" & StringRegExpReplace($sInput, ".*?[?&]([^=]+)=([^&]*)", "'&Assign('${1}','${2}')&'") & "'" & @LF)
    Local $sExtract = Execute("'" & StringRegExpReplace($sInput, ".*?[?&]([^=]+)=([^&]*)", "'&Assign('${1}','${2}')&'") & "'")
Else ; variable has single quotes
    ;ConsoleWrite('"' & StringRegExpReplace($sInput, ".*?[?&]([^=]+)=([^&]*)", '"&Assign("${1}","${2}")&"') & '"' & @LF)
    Local $sExtract = Execute('"' & StringRegExpReplace($sInput, ".*?[?&]([^=]+)=([^&]*)", '"&Assign("${1}","${2}")&"') & '"')
EndIf

ConsoleWrite('$var1=' & $var1 & @CRLF & _
        "$var2=" & $var2 & @CRLF & _
        "$var3=" & $var3 & @CRLF & _
        "$var4=" & $var4 & @CRLF)

Should the variable values have both double quotes and single quotes, then use jguinch's example.
