MS Access Extract all text between brackets to new query - regex

Question

I have a multi-line string variable that holds a large data string. Some of that data is enclosed between square brackets.
Example data variable:
[text 123]
text [text] 234 [blah] blah
some more [text 123]
I need to extract all the data between the square brackets into a query or table, so it would be something like this:
text 123
test
blah
text 123
Here is my VBA code below:
Dim dataString As String
dataString = "test [field 1] mroe text [field 2] etc"
Dim searchStr As String
Dim regExp As Object
Dim colregmatch As MatchCollection
Dim match As Variant
searchStr = dataString
Set regExp = CreateObject("vbscript.regexp")
With regExp
.pattern = "(?<=\[)(.*?)(?=\])"
.IgnoreCase = True
.Global = True
.Multiline = True
End With
Set colregmatch = regExp.Execute(searchStr)
If colregmatch.Count <> 0 Then
For Each match In colregmatch
MsgBox match.Value
Debug.Print match.Value
Next
End If
Set colregmatch = Nothing
Set regExp = Nothing
UPDATE: I get a 5017 run time error when using this pattern. If I use "[([^]]+)]" as the pattern, it works but the brackets are not removed...

The following regex should work:
/(?<=\[).*?(?=\])/gm
See Regex Demo of the regex in action.
Regex Breakdown:
(?<=\[): Positive lookbehind
\[: matches the character [ literally (case sensitive)
.*?: matches any character (except for line terminators) lazily (as few as possible)
(?=\]): Positive lookahead
\]: matches the character ] literally (case sensitive)
gm: global and multi-line modifiers
