I have been using your product for more than 6 years and I finally upgradet to the latest veriosn. There was rather a lot of changes I had to do in my code and I have managed most of them. However, I need help with the following: I have this line of code;

doc.Range.Replace(new Regex((@"[[Lönetillägg]]"), RegexOptions.IgnoreCase), new Utskick.ReplaceEvaluator(), false);

which is marked as obsolete. The ReplaceEvaluator looks like this:

public class ReplaceEvaluator : IReplacingCallback
    ReplaceAction IReplacingCallback.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);

        // Create Document Buidler 
        DocumentBuilder builder = new DocumentBuilder(e.MatchNode.Document as Aspose.Words.Document);

        builder.MoveTo((Run)runs[runs.Count - 1]);

        string bookm = e.Match.Value.Replace("[[", "").Replace("]]", "");
        //Your code comes here
        // Now remove all runs in the sequence.
        foreach (Run run in runs)

        // Signal to the replace engine to do nothing because we have already done all what we wanted.
        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;

What shall I do instead?

Best regards

Hi Robert,

Thanks for your inquiry. Please note that ReplaceAction, IReplacingCallback and ReplacingArgs are now moved to Aspose.Words.Replacing namespace.Please refer to the release notes:
Aspose.Words for .NET 16.7.0 Release Notes

Please use the following code to find and replace the text.

FindReplaceOptions options = new FindReplaceOptions();
options.ReplacingCallback = new ReplaceEvaluator();
int count = doc.Range.Replace(new Regex((@"\[\[Lönetillägg\]\]")), "", options);
