Why is my pattern wrong in StringRegExp?

[Noobster24]

Hi,

my program creates a txt-file with info from a website, sometimes there is '&' (HTML &), now i want to replace this '&'...

This is the function to pick the names and id's from the txt-file:

Func _SRE_Between($s_FilePath, $s_Start, $s_End)
    $h_FRead = FileRead($s_FilePath, FileGetSize($s_FilePath))
    $a_Array = StringRegExp($h_FRead, '(?:' & $s_Start & ')(.*?)(?:' & $s_End & ')', 3)
    If Not @error Then Return $a_Array
EndFunc

I thought that I could do it like this:

Func _SRE_Between($s_FilePath, $s_Start, $s_End)
    $h_FRead = FileRead($s_FilePath, FileGetSize($s_FilePath))
    $a_Array = StringRegExp($h_FRead, '(?:' & $s_Start & ')(.*?)(?:' & $s_End & ')', 3)
    $a_Array = StringRegExpReplace($a_Array, '(?:&)', '&')
    If Not @error Then Return $a_Array
EndFunc

But that isn't working, what's the right pattern? (Yes, I have read this article: http://www.autoitscript.com/forum/index.ph...l=stringregexp)

could you post a sampling of the data to be parsed?

If the 2nd $a_Array = is an array you aren't using it as an array but a only as a string, if it isn't an $a_Array then the string returned would be blank anyway.

$s = 'this is a test & only a test'
$Test = _SRE_Between($s, 'this', 'only')
If IsArray($Test) Then
    For $i = 0 To UBound($Test) - 1
        MsgBox(0,'info', $Test[$i])
    Next
EndIf

Func _SRE_Between($s_FilePath, $s_Start, $s_End)
  ;Local $h_FRead = FileRead($s_FilePath, FileGetSize($s_FilePath))
    Local $h_FRead = $s_FilePath
    Local $a_Array = StringRegExp($h_FRead, '(?:' & $s_Start & ')(.*?)(?:' & $s_End & ')', 3)
    If IsArray($a_Array) And Not @error Then
        For $iCount = 0 To UBound($a_Array) - 1
            $a_Array[$iCount] = StringRegExpReplace($a_Array[$iCount], '(?:&)', '&')
        Next
        Return $a_Array
    EndIf
    Return 0
EndFunc

Edit:

And now that I "really" look at it, this would be much faster I'm sure:

$s = 'this is a test & only a test'
$Test = _SRE_Between($s, 'this', 'only')
If IsArray($Test) Then
    For $i = 0 To UBound($Test) - 1
        MsgBox(0,'info', $Test[$i])
    Next
EndIf

Func _SRE_Between($s_FilePath, $s_Start, $s_End)
   ;Local $h_FRead = FileRead($s_FilePath, FileGetSize($s_FilePath))
    Local $h_FRead = $s_FilePath
    $sReplace = StringRegExpReplace($h_FRead, '(?:&)', '&')
    Local $a_Array = StringRegExp($sReplace, '(?:' & $s_Start & ')(.*?)(?:' & $s_End & ')', 3)
    If IsArray($a_Array) And Not @error Then Return $a_Array
    Return 0
EndFunc

Damn, that looks complicated, i'll taak a look at that later, must go now, thank you all
