Hey bro, I have a question.
How do I clone anything between the two words “table2” and “table3” into a new document?

@quanghieumylo, you can use the following example:

Document doc = new Document("a.docx");

SearchOnlyCallback searchCallback = new SearchOnlyCallback();

FindReplaceOptions opts = new FindReplaceOptions()
{
    ReplacingCallback = searchCallback
};

// Find the node containing Table1.
doc.Range.Replace("Table1", "", opts);
Node table1Node = searchCallback.foundNode;
searchCallback.foundNode = null;

// Find the node containing Table3.
doc.Range.Replace("Table3", "" , opts);
Node table3Node = searchCallback.foundNode;

// Extract nodes between Table1 and Table3.
var nodes = ExtractContentHelper.ExtractContent(table1Node, table3Node, false);

// Add the found nodes to a new document.
Document newDoc = (Document)doc.Clone(false);
newDoc.RemoveAllChildren();
newDoc.EnsureMinimum();

NodeImporter importer =  new NodeImporter(doc, newDoc, ImportFormatMode.KeepSourceFormatting);

foreach(Node node in nodes)
    newDoc.LastSection.Body.AppendChild(importer.ImportNode(node, true));

newDoc.Save("new.docx");

internal class SearchOnlyCallback : IReplacingCallback 
{
    public ReplaceAction Replacing(ReplacingArgs args)
    {
        foundNode = args.MatchNode;
        return ReplaceAction.Stop;
    }

    public Node? foundNode = null;
}

The code for the ExtractContentHelper class can be found here.

I tried the code you sent and had success with the original file.
However, when I use that code with the new file, the data is still in a table.

@quanghieumylo, to make the example work with a.docx and a1.docx, please replace the ExtractContentHelper.GetAncestorInBody method with the following code:

private static Node GetAncestorInBody(Node startNode)
{
    while (startNode.ParentNode.NodeType != NodeType.Cell &&
           startNode.ParentNode.NodeType != NodeType.Body)
        startNode = startNode.ParentNode;
    return startNode;
}
