Hello,
Is it possible without using bookmarks remove text between two lines?
Please see attached file.
First line with words: APPENDIX “A”
Second line with words: END OF APPENDIX “A”
Then insert another document between these two lines.
Thanks,
RK

Hi Rudolf,
Thanks for your request. I think, you can use a similar approach suggested here to extract/remove content between user defined strings and then insert new content:
https://forum.aspose.com/t/99344However, you should note that there were few changes in Aspose.Words API. So you should use IReplacingCallback instead of ReplaceEvaluator:

Hope this helps. Please let me know if you need more assistance, I will be glad to help you.
Best regards,

Hi, Alexey,
Can I programmatically create bookmark in the existing document?
For instance, programmatically find word “Appendix”, highlighted it and create new bookmark.
Thanks,
RK

Hello
Thanks for your inquiry. I think in your case you can try using IReplacingCallback. Please see the following link for more information and to find some code examples:

Hello
Thanks for your request. Please try using the following code:

Document doc = new Document("C:\\Temp\\sample.doc");
// We want the "your document" phrase to be highlighted.
Regex regex1 = new Regex("APPENDIX \"A\"");
Regex regex2 = new Regex("END OF APPENDIX \"A\"");
doc.Range.Replace(regex1, new ReplaceEvaluatorFindAndReplace(), true);
doc.Range.Replace(regex2, new ReplaceEvaluatorFindAndReplace(), true);
doc.Range.Bookmarks["APPENDIX"].Text = "New Content";
doc.Save("C:\\Temp\\out.doc");

private class ReplaceEvaluatorFindAndReplace: IReplacingCallback
{
    ///
    /// This method is called by the Aspose.Words find and replace engine for each match.
    ///
    ReplaceAction IReplacingCallback.Replacing(ReplacingArgs e)
    {
        DocumentBuilder builder = new DocumentBuilder((Document) e.MatchNode.Document);
        // This is a Run node that contains either the beginning or the complete match.
        Node currentNode = e.MatchNode;
        builder.MoveTo(currentNode);
        bool bookmarkInserted = false;
        foreach(BookmarkStart bookmarkStart in e.MatchNode.Document.GetChildNodes(NodeType.BookmarkStart, true))
        {
            if (bookmarkStart.Bookmark.Name == "APPENDIX")
            {
                bookmarkInserted = true;
                builder.EndBookmark("APPENDIX");
            }
        }
        if (!bookmarkInserted)
            builder.StartBookmark("APPENDIX");
        // 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 highlighting.
        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);
        }
        // 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.Stop;
    }
}
///
/// 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;
}
