ASP經典正則表達式在.Net中的行爲不同於.net

Question

我有這個正則表達式，它在.Net中工作 - 但不在ASP Classic中。它也適用於RegExr

它用於用逗號替換空格，除非空格在引號內。

dim strSearch 
dim strPattern 
strPattern = "\s(?=(?:[^\x22]*\x22[^\x22]*\x22)*[^\x22]*\z)" '\x22 = " (dbl quotes) 

strSearch = The "quick brown" fox jumps 

strSearch = ereg_replace(strSearch, pattern, ",", true) 

response.write(strSearch) 

'Expect: The,"quick brown",fox,jumps 
'Actual: The "quick brown" fox jumps 

function ereg_replace(strOriginalString, strPattern, strReplacement, varIgnoreCase) 
    dim objRegExp : set objRegExp = new RegExp 
    with objRegExp 
    .Pattern = strPattern 
    .IgnoreCase = varIgnoreCase 
    .Global = False 
    .Multiline = False 
    end with 
    ereg_replace = objRegExp.replace(strOriginalString, strReplacement) 
    set objRegExp = nothing 
end function 

我需要改變什麼才能使模式適應ASP Classic？

Answer 1

我敢肯定這樣做的原因是，\z錨不受ASP正則表達式的支持，請嘗試更換與$：

\s(?=(?:[^\x22]*\x22[^\x22]*\x22)*[^\x22]*$)
