I want find The title that is fixed
Random random words1 that I want replace
random text words2 that I want replace
random word words3 that I want replace
The end.
Because I want to replace in the text of the text is random text, but the title of the random text in front is fixed,In sample text:I want find The title that is fixed,I hope to find a fixed by words,Then find a random text location

Hi there,

Thanks for sharing the detail. In your case, we suggest you following solution.

  1. Please implement IReplacingCallback interface.
  2. In IReplacingCallback.Replacing, create an instance of DocumentBuilder class.
  3. Move the cursor to the matched node.
  4. Insert the contents according to your requirements.
  5. Remove the matched text.

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

Document doc = new Document(MyDir + "input.docx");
doc.Range.Replace("Random", "", new FindReplaceOptions { ReplacingCallback = new ReplaceHandlerText(), Direction = FindReplaceDirection.Backward});
doc.Save(MyDir + "output.docx");

class ReplaceHandlerText : 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);
        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);
        }
        DocumentBuilder builder = new DocumentBuilder((Document)e.MatchNode.Document);
        builder.MoveTo((Run)runs[0]);
        builder.Write("Replace text with Random");
        // Remove matched text
        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);
        run.ParentNode.InsertAfter(afterRun, run);
        return afterRun;
    }
