Regular Expression Result differs from StringInString

[philkryder]

The brief reproducer below produces different results for  StringInStr as contrasted with StringRegExp.

I had expected both would find the string at offset 21.
Why would StringRegExp give a value of 1 - with zero @error?

Local $iOffsetStringInString = StringInStr($sHTML,$sPattern)
$ierrorSave = @error
$iextendedSave = @extended
ConsoleWrite(@CR & "$iOffsetStringInString>" & $iOffsetStringInString & @cr & $ierrorSave & @CR & $iextendedSave & @CR)

Local $iOffsetStringRegExp = StringRegExp($sHTML,$sPattern)
$ierrorSave = @error
$iextendedSave = @extended
ConsoleWrite(@CR & "$iOffsetStringRegExp>" & $iOffsetStringRegExp & @cr & $ierrorSave & @CR & $iextendedSave &@CR)

Perhaps one is 0 based while the other is 1 based.

StringInStr is 1 based I believe, meaning the first character is 1, not 0.

EDIT: mis-read.

stringregexp return is

1 = it found a match

0 = No ErrorLevel set (or set to 0)

0 = there were no errors found so no offset of error (so either not set or set to 0)

Flag = $STR_REGEXPARRAYMATCH (1)
@error=0 Array is valid. Check @extended for next offset  

Local $sHTML = 'class="groupHeader">Special Circumstances</h2>'

Local $sPattern = 'Special Circumstances'

Local $iOffsetStringInString = StringInStr($sHTML,$sPattern)
ConsoleWrite("$iOffsetStringInString>" & $iOffsetStringInString & @CR)

Local $iOffsetStringRegExp = StringRegExp($sHTML,$sPattern, 1) ;<<<< flag 1
$iextendedSave = @extended/2
ConsoleWrite("$iOffsetStringRegExp>" & $iextendedSave &@CR)

thanks much - gosh, I read that and just didn't get it.

Here though is an extended reproducer that exhibits more closely the problem I'm grappling with.

In this case, I don't see why StringRegExp doesn't return a 1 for the last example.

how can String in string  match 'groupheader">Special Circumstances'
But StringRegExp not match with 'groupheader">Special Circumstances'
