StringRegExpReplace - start of file?

[Madness]

I need to search for a heading in a text file and delete everything from the beginning of the file to the heading. Is there coding in regular expressions to do this? I see some REs support ^^ as the beginning of a file. Or should I be doing this a different way. I'm reading the contents of a file using FileRead into a variable, then working on the variable, and writing this back to a file. I need to run numerous globals on this, plus remove some items.

Also, are there limits to the amount of text using FileRead that can be read into a string variable?

Looks like this does the trick:

(?s)(?m)^.*search item

Still would like to know if there are any limits in the file size that can be read with FileRead though.

$sStr = stringRegExpReplace(FileRead("somefile.txt"), "(?i)(?s)^.*?(search string.*)$", $1)

I wrote a function that behaves like string split except the deliminator is a regular expression.

You will just need to query the resulting array for what you want.

#include <Array.au3>

;~ ---for example
$sString="abc124bcd2cde3def4efg"

$sRegExp="[0-9]"
$aResult=_REsplit($sString,$sRegExp)
_arraydisplay($aresult)

$sRegExp="124"
$aResult=_REsplit($sString,$sRegExp)
_arraydisplay($aresult)

$sRegExp="[cd]"
$aResult=_REsplit($sString,$sRegExp)
_arraydisplay($aresult)
;~------

Func _RESplit($sString, $sRegExp, $iRegExBehave=3 )
    Local $aReturn[1]
    $aReturn[0]=$sRegExp

    $aSplits = StringRegExp($sString, $sRegExp,$iRegExBehave)

    For $x = 0 To UBound($aSplits) - 1
        if StringInStr($sString, $aSplits[$x]) then
            $iLeft = StringInStr($sString, $aSplits[$x])-1
            $iRight = StringLen($sString)-($iLeft+stringlen($aSplits[$x]))


            _ArrayAdd($aReturn, StringLeft($sString, $iLeft))
            $sString = StringRight($sString, $iRight)


        EndIf

    Next
    _ArrayAdd($aReturn, $sString)
    Return($aReturn)
EndFunc   ;==>_RESplit

Thanks George. I really like your Toolkit. Nice job!
