Hi Joebet,

Thanks for your inquiry. Please use following code example to achieve your requirements. Hope this helps you.

Document doc = new Document(MyDir + "in.docx");
doc.Range.Replace(new Regex(@"##mymergefield##"), new FindandInsertHtml(@"<b>my cool text</b>"), false);
doc.Save(MyDir + "Out.docx");

class FindandInsertHtml : IReplacingCallback
{
    private String mhtml;
    public FindandInsertHtml(String html)
    {
        mhtml = html;
    }
    /// 
    /// This method is called by the Aspose.Words find and replace engine for each match.
    /// 
    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))
        {
            runs.Add(currentNode);
            remainingLength = remainingLength - currentNode.GetText().Length;
            // Select the next Run node.
            // Have to loop because there could be other nodes such as BookmarkStart etc.
            do
            {
                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);
            runs.Add(currentNode);
        }
        // create Document Buidler and insert MergeField
        DocumentBuilder builder = new DocumentBuilder(e.MatchNode.Document as Document);
        builder.MoveTo((Run)runs[runs.Count - 1]);
        builder.InsertHtml(mhtml);
        // Now remove all runs in the sequence.
        foreach (Run run in runs)
            run.Remove();
        // 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);
