正则表达式模式在 VB 脚本中不起作用

问题描述

我有这个 VBS 代码:

I have this VBS code:

Option Explicit

   Dim reMethod, reInterface
    Dim vaction
    Dim fileService
    Dim mService
    Dim lineService
    Dim objFSO

    Const ForReading = 1

    Set objFSO = CreateObject("Scripting.FileSystemObject")
    Set fileService = objFSO.OpenTextFile("GIISAssuredController.java" , ForReading)

    Set reMethod = new regexp
    reMethod.Pattern = """\w+?""\.equals\(ACTION\)[\s\S]*?\{[\s\S]*?\.([^(]*)\("
    reMethod.IgnoreCase = True
    reMethod.Global = True

    Do Until fileService.AtEndOfStream
        lineService = fileService.ReadLine
        For Each mService In reMethod.Execute(lineService)
           vaction = mService.Submatches(0)
            Set reInterface = new regexp

            Wscript.Echo vaction

        Next
    Loop

和'GISAssuredController.java':

And 'GIISAssuredController.java':

} else if ("hello".equals(ACTION))         {
   Integer assuredNo = giisAssuredService.saveAssured(assured);

正则表达式模式不起作用.

The regex pattern is not working.

我期望输出是:

saveAssured

但相反，它没有回响任何东西.我在这里尝试了正则表达式模式 > https://regex101.com/r/kH3aZ4/1，它正在获取saveAssured"字符串.

But instead, it's not echoing anything. I tried the regex pattern here > https://regex101.com/r/kH3aZ4/1, and it's getting the 'saveAssured' string.

这个问题与:Multiline REGEX using VB Script有关

推荐答案

如果表达式需要匹配一个生成多行的文本，但是你逐行读取文件并逐行测试，永远不会有匹配.

If the expression needs to match a text that spawns over multiple lines, but you read the file line by line and test line by line, there will never be a match.

Option Explicit

    Const ForReading = 1

Dim code
    code = CreateObject("Scripting.FileSystemObject" _
           ).OpenTextFile("GIISAssuredController.java" , ForReading _
           ).ReadAll()

Dim mService

    With new RegExp
        .Pattern = """\w+?""\.equals\(ACTION\)[\s\S]*?\{[\s\S]*?\.([^(]*)\("
        .IgnoreCase = True
        .Global = True
        For Each mService in .Execute(code)
            WScript.Echo mService.Submatches(0)
        Next
    End With
