I have this text file that I need to check:
} else if ("saveAssured".equals(ACTION)) {
Integer assuredNo = giisAssuredService.saveAssured(assured);
The pattern will include a variable:
var = "saveAssured"
reMethod.Pattern = """& var &""[.]equals\(ACTION\).{\n.\w+?.=.\w+?[.](\w+?)\(\w+?\)"
I need to capture the second 'saveAssured' from the text file. And the '\n' (new line) seems to be not working. Did I used it right? What other steps can I try?

JavaScript and VBScript do not have an option to make the dot match line break characters. In those languages, you can use a character class such as
[\s\S]to match any character. This character matches a character that is either a whitespace character (including line break characters), or a character that is not a whitespace character. Since all characters are either whitespace or non-whitespace, this character class matches any character.
And have a look at https://regex101.com/r/kH3aZ4/1
Test is for JavaScript but since they have the same Regex flavor, that pattern will also work with VBScript.
Dim reMethod
Set reMethod = New RegExp
reMethod.IgnoreCase = True
reMethod.Pattern = """saveAssured""\.equals\(ACTION\)[\s\S]*?\{[\s\S]*?\.([^(]*)\("
MultiLine property? - Ref Regular Expression Programming (Scripting) - Section: Flags
dot matches newline behavior and the .Multiline property does not supply that. [\s\S] instead . is the way to go with VBScript.The information around multiline in VBScript expressions is a bit inconsistent. The VBScript RegExp object does support them but the property is not well documented.
From Regular Expression Programming (Scripting)
Flags
In the JScript regular expression /abc/gim, the g specifies the global flag, the i specifies the ignore case flag, and the m specifies the multiline flag.
In VBScript, you can specify these flags by setting the equivalent properties to True.
The following table shows the allowed flags.
JScript flag VBScript property If flag is present or property is True
g Global Find all occurrences of the pattern in the searched string instead of just the first occurrence. i IgnoreCase The search is case-insensitive. m Multiline ^ matches positions following a \n or \r, and $ matches positions before \n or \r. Whether or not the flag is present or the property is True, ^ matches the position at the start of the searched string, and $ matches the position at the end of the searched string.
Below is an example of using MultiLine.
Option Explicit
Dim rx: Set rx = New RegExp
Dim matches, match
Dim data: data = Array("This is two lines of text", "This is the second line", "Another line")
Dim txt: txt = Join(data, vbCrLf)
With rx
.Global= True
.MultiLine = True
.Pattern= "line$"
End With
Set matches = rx.Execute(txt)
WScript.Echo "Results:"
For Each match In matches
WScript.Echo match.Value
Next
Output:
Results:
line
line
The difference with MultiLine set to False.
Output:
Results:
line
