Word VBA macro on parentheticals-CodePudding

I have been using the following macro to pull out items in parenthesis to comments in word:

'
' CommentBubble Macro
'
'
Dim myRange As Range
Set myRange = ActiveDocument.Content
searchtext = "\(*\)"

With myRange.Find
    .MatchWildcards = True
    Do While .Execute(findText:=searchtext, Forward:=True) = True
      If Len(myRange.Text) > 4 Then
        ActiveDocument.Comments.Add myRange, myRange.Text
        myRange.Text = ""
      End If
    Loop
 End With
End Sub

The reason I have the length of the text be > 4 is because these are legal documents and I don't want to isolate strings that have things like "in the following conditions: (i) condition 1, (ii) condition 2, etc."

However, here is a snippet of text for which the above code breaks:

This is sample text (with some additional text) that does stuff (with more stuff) and represents 39.4% of shares on the effective date (before giving effect, with some conditions such as ( some stuff (i) and some stuff (ii) with final stuff) and more final stuff) which is subject to  (some conditions here) and conclude here.

If you run this you will get the following result:

This is sample text  that does stuff  and represents 39.4% of shares on the effective date  and some stuff (ii) with final stuff) and more final stuff) which is subject to   and conclude here.

As you can see the nested parenthesis cause some trouble. Any advice?

Thanks!

CodePudding user response：

You are trying to match parentheses which in Word is a difficult and thankless task as Word only sees opening and closing parentheses as individual characters and not automatically matched by word. The code below finds matching parentheses, eliminates trailing spaces, habdles the case of no parentheses being present, and errors out if you have unbalanced errors. I've left in debugging statements so that you can uncomment them to see what is happening.

Option Explicit

Public Sub ttest()

    Dim myRange As Word.Range
    Set myRange = ActiveDocument.StoryRanges(wdMainTextStory)
    myRange.Collapse direction:=wdCollapseStart
    
    
    Set myRange = NextParenRange(myRange)
    
    Do Until myRange Is Nothing
    
        DoEvents
        
        Debug.Print myRange.Text
        Dim myDupRange As Word.Range
        Set myDupRange = myRange.Duplicate
        myRange.Collapse direction:=wdCollapseEnd
        If myDupRange.Characters.Last.Next.Text = " " Then myDupRange.MoveEnd Count:=1
        myDupRange.Delete
        Set myRange = NextParenRange(myRange)
        
    
    Loop
    
End Sub

Public Function NextParenRange(ByVal ipRange As Word.Range) As Word.Range

    Const OpenP As String = "("
    Const CloseP As String = ")"
    
    Dim myRange As Word.Range
    Set myRange = ipRange.Duplicate
    
    'If myRange.Start <> myRange.End Then myRange.Collapse direction:=wdCollapseStart
    
    'exit if no parentheses exist
    'Debug.Print myRange.Start
    If myRange.MoveUntil(cset:=OpenP) = 0 Then
    
        Set NextParenRange = Nothing
        Exit Function

        ' allows VBA to respond to a break key press
        DoEvents
        
        ' if we run out of parentheses before we get back to zero then flag an error
        If myRange.MoveEndUntil(cset:=OpenP & CloseP) = 0 Then
        
            VBA.Err.Raise 17, "Unbalanced parentheses in document"

        myParenCount = myParenCount   IIf(myRange.Characters.Last.Text = OpenP, 1, -1)
        
    
    Loop
