Move Cursor in between word (inside any word in run)

I am using latest Aspose. dll 15.X.X.X.

I have one paragraph and one run inside it. This run can spread over multiple lines in word document.
I want to insert bookmark in the middle somewhere.

For e.g “The document contains this text”.
Kindly note this is in one Run Only

I want to insert bookmark before and after word “contains”.

After going through some samples on the forum i got few ideas, however i would like to know

  1. How to move cursor to the end of a given Run?
  2. How to move cursor to the end of a given Paragraph?
  3. How can i insert bookmark at the end of a run node?
  4. Can i insert bookmark after the Run or Paragraph node?


Thanks for your inquiry. You can insert bookmark by using the following code:

Document doc = new Document(MyDir + @"in.docx");
doc.Range.Replace(new System.Text.RegularExpressions.Regex("contains"), new ReplaceEvaluator(), false);
doc.Save(MyDir + @"15.4.0.docx");
private class ReplaceEvaluator : Aspose.Words.IReplacingCallback
    Aspose.Words.ReplaceAction Aspose.Words.IReplacingCallback.Replacing(Aspose.Words.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);
        DocumentBuilder builder = new DocumentBuilder((Document)e.MatchNode.Document);
        builder.MoveTo((Run)runs[runs.Count - 1]);
        return ReplaceAction.Skip;
    /// Splits text of the specified run into two runs.
    /// Inserts the new run just after the specified run.
    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;

Secondly, you can move cursor to any node in document. Please refer to the following article:

I hope, this helps.
