Hi Ken,

Thanks for your inquiry. You can try using code like the following to remove content before and after bookmark:

///
/// Removes all content before specified node
///
public void RemoveContentBeforeNode(Document doc, Node endNode)
{
    Node curNode = endNode.PreviousPreOrder(doc);
    while (curNode != null)
    {
        // Move to next node
        Node nextNode = curNode.PreviousPreOrder(doc);
        // Check whether current contains start node
        if (curNode.IsComposite)
        {
            if (!(curNode as CompositeNode).GetChildNodes(NodeType.Any, true).Contains(endNode))
            {
                nextNode = curNode.PreviousSibling;
                curNode.Remove();
            }
        }
        else
        {
            curNode.Remove();
        }
        curNode = nextNode;
    }
}
///
/// Removes all content after specified node
///
public void RemoveContentAfterNode(Document doc, Node startNode)
{
    Node curNode = startNode.NextPreOrder(doc);
    while (curNode != null)
    {
        // Move to next node
        Node nextNode = curNode.NextPreOrder(doc);
        // Check whether current contains start node
        if (curNode.IsComposite)
        {
            if (!(curNode as CompositeNode).GetChildNodes(NodeType.Any, true).Contains(startNode))
            {
                nextNode = curNode.NextSibling;
                curNode.Remove();
            }
        }
        else
        {
            curNode.Remove();
        }
        curNode = nextNode;
    }
}

In your case, startNode is BookmarkEnd of your bookmark, if you need to remove content after bookmark. If you need to remove content before bookmark endNode is BookmarkStart of your bookmark.
Best regards,

Hi

Thanks for your inqiry. You can use code like the following:

BookmarkStart start = doc.Range.Bookmarks["mybookmark"].BookmarkStart;
BookmarkEnd end = doc.Range.Bookmarks["mybookmark"].BookmarkEnd;

Hi

Thank you for additional information. Please try using the following modified version of the method:

///
/// Removes all content after specified node
///
public void RemoveContentAfterNode(Document doc, Node startNode)
{
    Node curNode = startNode.NextPreOrder(doc);
    while (curNode != null)
    {
        // Move to next node
        Node nextNode = curNode.NextPreOrder(doc);
        // Check whether current contains start node
        if (curNode.IsComposite)
        {
            if (!(curNode as CompositeNode).GetChildNodes(NodeType.Any, true).Contains(startNode))
            {
                if (curNode.NextSibling != null)
                    nextNode = curNode.NextSibling;
                curNode.Remove();
            }
        }
        else
        {
            curNode.Remove();
        }
        curNode = nextNode;
    }
}

Hope this helps.
Best regards,
