INI file - retrieve a section name by key name in VBS - vbscript

Question

I would like to retrieve a section name from an INI file with only a unique key name
My ini file :
...
[Area.104]
Title=Central North America
Local=Scenery\NAMC
Layer=104
Active=TRUE
Required=FALSE
[Area.105]
Title=Eastern North America
Local=Scenery\NAME
Layer=105
Active=TRUE
Required=FALSE
[Area.106]
Title=Western North America
Local=Scenery\NAMW
Layer=106
Active=TRUE
Required=FALSE
...
How can I get section name [Area.105] from unique key Title=Eastern North America ???
Thank you

Answer 1

I have two ways of finding the required Area code:
METHOD 1
Option Explicit
Dim strFilePath, ofso, ofile, strFileData, strKey, strPrev, strCurr
strFilePath="" '<-- Enter the absolute path of your .ini file in this variable
Set ofso = CreateObject("scripting.FileSystemObject")
Set ofile = ofso.OpenTextFile(strFilePath,1,False)
strKey = "Eastern North America" '<-- Enter Unique title for which you want the Area code
strPrev=""
strCurr=""
Do
strCurr = ofile.ReadLine
If InStr(1,strCurr,strKey)<>0 Then
Exit Do
End If
strPrev = strCurr
Loop Until ofile.AtEndOfStream
MsgBox strPrev
Set ofile = Nothing
Set ofso = Nothing
METHOD 2(Using Regular Expression)
Option Explicit
Dim strFilePath, ofso, ofile, strFileData, strKey, re, objMatches
strFilePath="" '<-- Enter the absolute path of your .ini file in this variable
Set ofso = CreateObject("scripting.FileSystemObject")
Set ofile = ofso.OpenTextFile(strFilePath,1,False)
strFileData = ofile.ReadAll()
ofile.Close
strKey = "Eastern North America" '<-- Enter Unique title for which you want the Area code
Set re = New RegExp
re.Global=True
re.Pattern="\[([^]]+)]\s*Title="&strKey
Set objMatches = re.Execute(strFileData)
If objMatches.Count>0 Then
MsgBox objMatches.Item(0).Submatches.Item(0)
End If
Set re = Nothing
Set ofile = Nothing
Set ofso = Nothing

Regex Explanation:
\[ - matches literal [
([^]]+) - capture 1+ occurrence of any character which is not ] in a group
] - matches literal ]
\s* - matches 0+ white-spaces(which include the newline characters)
Title= - matches the text Title=. This is then concatenated with the variable strKey containing the value of unique title.
