String subtraction

[mohammadezazi]

Excuse me for my weakness.

What is the quick way to subtract a string from another.

For example:

$sMain = "quick way to subtract a string from another"

$sSubString = "y to subt"

How I can get this result:

$sResult = $sMain - $sSubString = "quick waract a string from another"

StringReplace.

This example gives options to deal with more than one occurrence of the $sSubString in $sMain to be substracted.

This gives more than you required because I would not have been motivated to reply otherwise. And I put that remark in anticipating the "too complicated", "over thinking" statements I hope won't follow.

Local $sMainMinusSubString
Local $sMain = "quick way to subtract a string from another"
Local $sSubString =  "y to subt" ; "a" ;
Local $iOccur = 0 ; 2 for 2nd occurrence; 0 for all occurrences; Negatives numbers count the occurrence from end of string.

If $iOccur Then ; Not 0 is True
    $sMainMinusSubString = StringRegExpReplace($sMain, "(?is)(^.{" & (StringInStr($sMain, $sSubString, 0, $iOccur) - 1) & "})(" & $sSubString & ")(.*$)", "\1\3")
Else
    $sMainMinusSubString = StringReplace($sMain, $sSubString, "")
EndIf

MsgBox(0, "Result", $sMainMinusSubString)
