多行文本的 Vbscript 正则表达式？

Question

"value:=This customer has one or more active tax exemptions available\.
\n
 \n
Do you want to apply a tax exemption to this transaction\?"

我试过像 "Value:=This.*" 这样的正则表达式，但它不能识别整个文本。请告诉我如何通过仅验证整个文本中的第一个单词来使用 VbScript 正则表达式识别整个文本。谢谢。

Answer 1

参见：How do I match any character across multiple lines in a regular expression?

例如：

Dim s : s = "value:=This customer has one or more active tax exemptions available." & vbCrLf & vbCrLf & "Do you want to apply a tax exemption to this transaction?"
With New RegExp
    .Pattern = "^value:=This(.|\n|\r)*"
    With .Execute(s)
        WScript.Echo .Item(0).Value
    End With
End With

...其 .Pattern 以 (^) 'value:=This' 开头，后跟任意字符 (.)、换行符（又名换行符) (\n)，或回车 return (\r) 重复零次或多次 (*).

输出：

value:=This customer has one or more active tax exemptions available.

Do you want to apply a tax exemption to this transaction?

希望这对您有所帮助。

Answer 2

我猜，

value:=This\b[\s\S]*

可能工作正常。
