Find & Hide all Text in Word DOCX Document which is Inside the Curly Brackets using C# .NET Code

Dear Community and lovely Support!

I would like to hide the text within the curly bracket with those curly brackets in the docx file, please find an attached sample. (14.3 KB)


The following C# code example of Aspose.Words for .NET API will hide all the text in Word DOCX document which is contained within curly brackets:

Document doc = new Document("C:\\Temp\\HideBracketText_test_file\\HideBracketText_test_file.docx");

FindReplaceOptions findReplaceOptions = new FindReplaceOptions();
findReplaceOptions.ReplacingCallback = new HandleReplacingCallback();
findReplaceOptions.Direction = FindReplaceDirection.Backward;

doc.Range.Replace(new Regex("\\{(.*?)\\}"), "", findReplaceOptions);

private class HandleReplacingCallback : IReplacingCallback
    public ReplaceAction Replacing(ReplacingArgs e)
        // This is a Run node that contains either the beginning or the complete match.
        Node currentNode = e.MatchNode;

        // The first (and may be the only) run can contain text before the match,
        // in this case it is necessary to split the run.
        if (e.MatchOffset > 0)
            currentNode = SplitRun((Run)currentNode, e.MatchOffset);

        // This array is used to store all nodes of the match for further removing.
        ArrayList runs = new ArrayList();

        // Find all runs that contain parts of the match string.
        int remainingLength = e.Match.Value.Length;
        while (
        (remainingLength > 0) &&
        (currentNode != null) &&
        (currentNode.GetText().Length <= remainingLength))
            remainingLength = remainingLength - currentNode.GetText().Length;

            // Select the next Run node.
            // Have to loop because there could be other nodes such as BookmarkStart etc.
                currentNode = currentNode.NextSibling;
            while ((currentNode != null) && (currentNode.NodeType != NodeType.Run));

        // Split the last run that contains the match if there is any text left.
        if ((currentNode != null) && (remainingLength > 0))
            SplitRun((Run)currentNode, remainingLength);

        //Now Hide all Run nodes in the sequence.
        foreach (Run run in runs)
            run.Font.Hidden = true;

        return ReplaceAction.Skip;

    private static Run SplitRun(Run run, int position)
        Run afterRun = (Run)run.Clone(true);
        afterRun.Text = run.Text.Substring(position);
        run.Text = run.Text.Substring(0, position);
        run.ParentNode.InsertAfter(afterRun, run);
        return afterRun;
