VBScript RegEx : Replace Content - vbscript

Question

I want to update the Unbound_DNS configuration file from a raw source but I can not get the desired result.
I would like to format each entry (each line):
address=/abc.com/0.0.0.0
To
local-zone: "abc.com" redirect
local-data: "abc.com 86400 IN A 0.0.0.0"
Here is what I did (thanks to hackoofr):
Option Explicit
Dim URL,Save2File,ws
If Not WScript.Arguments.Named.Exists("elevate") Then
CreateObject("Shell.Application").ShellExecute WScript.FullName _
, """" & WScript.ScriptFullName & """ /elevate", "", "runas", 1
WScript.Quit
End If
URL = "https://raw.githubusercontent.com/notracking/hosts-blocklists/master/domains.txt"
Set ws = CreateObject("wscript.Shell")
Save2File = ws.ExpandEnvironmentStrings("%Windir%\Temp\test")
Call Download(URL,Save2File)
'**********************************************************************************************
Sub Download(URL,Save2File)
Dim File,Line,BS,ws,RegExp
On Error Resume Next
Set File = CreateObject("MSXML2.XMLHTTP")
File.Open "GET",URL, False
File.Send
If err.number <> 0 then
Line = Line & vbcrlf & "Error Getting File"
Line = Line & vbcrlf & "Error " & err.number & "(0x" & hex(err.number) & ") " & vbcrlf &_
err.description
Line = Line & vbcrlf & "Source " & err.source
MsgBox Line,vbCritical,"Error getting file"
Err.clear
wscript.quit
End If
If File.Status = 200 Then
'**********************************************************************************************

File.ResponseBody = RegExp.Replace(File.ResponseBody, "local-zone: \""$1\"" redirect $1" & ret & ">local-data: \""$1 3600 IN A $2\""")

Else
MsgBox "UpdateHostname.vbs : Unknown Error : " & File.Status,vbCritical,"UpdateHostname.vbs : Error getting file"
End If
End Sub

Thank you in advance for your help.
Edit 1:
The content does not change. File.ResponseBody returns the content correctly, but no modification by the regexp!

Answer 1

Replace the following code:
Set RegExp = CreateObject("VBScript.RegExp")
RegExp.IgnoreCase = True
RegExp.Global = True
RegExp.Pattern = "address=/(.*)/([0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3})"
File.ResponseBody = RegExp.Replace(File.ResponseBody, "local-zone: \""$1\"" redirect $1" & ret & ">local-data: \""$1 3600 IN A $2\""")
Set RegExp = Nothing
with this:
Dim objReg, strTest, objMatches, objMatch
Set objReg = New RegExp
strTest = File.ResponseBody 'address=/abc.com/0.0.0.0
objReg.Global = True
objReg.Pattern = "address=/(.*?)/(\d{1,3}(?:\.\d{1,3}){3})" 'abc.com gets stored in Group 1 and the IP address gets stored in Group 2
Set objMatches = objReg.Execute(strTest)
For Each objMatch In objMatches
strTest = "local zone: """ & objMatch.Submatches.Item(0) & """ redirect" & vbCrLf &_
"local data: """ & objMatch.Submatches.Item(0) & " 86400 in A " & objMatch.Submatches.Item(1)&""""
Next
File.ResponseBody = strTest
set objReg = Nothing
Click for Regex Demo(in the demo, / is escaped by \)
Regex Explanation:
address=/(.*?)/(\d{1,3}(?:\.\d{1,3}){3})
address=/ - matches address=/ literally
(.*?) - matches 0+ occurrences of any character(except a newline), as few as possible. The parenthesis are used to capture this match as group 1
/ - matches / literally
(\d{1,3}(?:\.\d{1,3}){3}) - matches a string of the pattern 12.222.212.33 and captures it in Group 2
Update:
Here is my final solution. From what I could understand from your code, you first get the response body from the server, modify and store the updated response in a file called test in the temp folder. Below is the code I have written to do the same thing. I have tested it on my system and the final output which gets stored in the C:\Windows\Temp\test.txt file looks correct as shown in the attached screenshot. Now, this may not be exactly what you want but you can get an idea from this. Store this code in a new vbs file and run it directly as it is.
Note: Since the response text from the server is very long, It takes a bit long to get executed. If you just want to see if it is working or not, uncomment the code inside the for loop. You will be able to see that you are getting the desired result for the first few URLs

Here is the update of the code that works very well based on the response of #Gurman and the comment of #Ansgar Wiechers. Thank you for your help
