Find Identical Bookmarks & Extract or Copy Bookmark's Content into another Word Document using C# .NET

SangeeN · May 14, 2022, 7:49am

I have two documents with same bookmark name and wanted to copy bookmark content from one document to another document.But Bookmark end throwing exception.

public void CopyBookmarkContentBetweenDocuments(List<string> bookmarkNames, string sourceFileName, string destinationFileName)
{
	var sourceDocument = new Document(sourceFileName);
	var destinationDocument = new Document(destinationFileName);

	foreach (var bookmarkName in bookmarkNames)
	{

		Bookmark bookmarkSourceDocument = CommonFunction.FindBookmark(sourceDocument, bookmarkName);
		if (bookmarkSourceDocument == null)
			continue;

		Bookmark bookmarkDestinationDocument = CommonFunction.FindBookmark(destinationDocument, bookmarkName);
		if (bookmarkDestinationDocument == null)
			continue;
		bookmarkDestinationDocument.Text = "";  // Remove possibly nodes enclosed by bookmark in destination document
		bookmarkDestinationDocument = CommonFunction.FindBookmark(destinationDocument, bookmarkName); // Get bookmark again. Necessary?

		NodeImporter imp = new NodeImporter(sourceDocument, destinationDocument, ImportFormatMode.KeepSourceFormatting);


		foreach (Node node in bookmarkSourceDocument.BookmarkStart.ParentNode)
		{
			Node impNode = imp.ImportNode(node, true);
			bookmarkDestinationDocument.BookmarkStart.ParentNode.AppendChild(impNode);
		}

	}
	destinationDocument.Save(destinationFileName);
}

@SangeeN,

After an initial test with the licensed latest (20.6) version of Aspose.Words for .NET , we were unable to reproduce any exception on our end. Please see this output DOCX document and try running the following code:

Output DOCX produced using 20.6.zip (12.6 KB)

C# Code:

var sourceDocument = new Document("E:\\Temp\\26dbb9c8-59fc-4862-8630-6fd08d3a3669\\Saksfremlegg.docx");
var destinationDocument = new Document("E:\\Temp\\26dbb9c8-59fc-4862-8630-6fd08d3a3669\\SaksprotokollElements.docx");

StringBuilder sb = new StringBuilder();
foreach (Bookmark bm in sourceDocument.Range.Bookmarks)
    sb.Append(bm.Name + ",");

string[] bookmarkNames = sb.ToString().Split(new char[] { ',' });

foreach (string bookmarkName in bookmarkNames)
{
    if (bookmarkName == "")
        continue;

    Bookmark bookmarkSourceDocument = sourceDocument.Range.Bookmarks[bookmarkName];
    if (bookmarkSourceDocument == null)
        continue;

    Bookmark bookmarkDestinationDocument = destinationDocument.Range.Bookmarks[bookmarkName];
    if (bookmarkDestinationDocument == null)
        continue;
    bookmarkDestinationDocument.Text = "";  // Remove possibly nodes enclosed by bookmark in destination document
    bookmarkDestinationDocument = destinationDocument.Range.Bookmarks[bookmarkName]; // Get bookmark again. Necessary?

    NodeImporter imp = new NodeImporter(sourceDocument, destinationDocument, ImportFormatMode.KeepSourceFormatting);

    foreach (Node node in bookmarkSourceDocument.BookmarkStart.ParentNode)
    {
        Node impNode = imp.ImportNode(node, true);
        bookmarkDestinationDocument.BookmarkStart.ParentNode.AppendChild(impNode);
    }

}
destinationDocument.Save("E:\\Temp\\26dbb9c8-59fc-4862-8630-6fd08d3a3669\\20.6.docx");

So, we suggest you please upgrade to the latest version.

Hi @awais.hafeez In Oppsummering part the whole content should be copied but only one line is copied to the destination document.

Output document should be like attachedSaksprotokollElements_after.zip (12.6 KB)

@SangeeN,

I think, you can implement the following workflow to meet this requirement:

Extract complete content from a Bookmark in source document
Move cursor to matching Bookmark’s location in destination document
Insert extracted Document at destination bookmark’s place

@awais.hafeez I have already tried this approach and I am getting exception in Extract when there is no nextSection. image.png (35.0 KB)

public void CopyBookmarkContentBetweenDocuments(List<string> bookmarkNames, string sourceFileName, string destinationFileName)
{
	var sourceDocument = new Document(sourceFileName);
	var destinationDocument = new Document(destinationFileName);
	var builder = new DocumentBuilder(destinationDocument);
	string fileName = Path.Combine(Path.GetDirectoryName(Assembly.GetExecutingAssembly().Location), "Data\\ExtractFile.doc");
	Document extractDoc = new Document(fileName);
	foreach (var bookmarkName in bookmarkNames)
	{
		try
		{
			Bookmark bookmarkSourceDocument = CommonFunction.FindBookmark(sourceDocument, bookmarkName);
			if (bookmarkSourceDocument == null)
				continue;

			Bookmark bookmarkDestinationDocument = CommonFunction.FindBookmark(destinationDocument, bookmarkName);
			if (bookmarkDestinationDocument == null)
				continue;
			bookmarkDestinationDocument.Text = "";  // Remove possibly nodes enclosed by bookmark in destination document
			bookmarkDestinationDocument = CommonFunction.FindBookmark(destinationDocument, bookmarkName); // Get bookmark again. Necessary?

			ArrayList extractedNodesInclusive = CommonFunction.ExtractContent(bookmarkSourceDocument.BookmarkStart, bookmarkSourceDocument.BookmarkEnd, true);
			Document dstDoc = CommonFunction.GenerateDocument(extractDoc, extractedNodesInclusive);
			builder.MoveToBookmark(bookmarkName, false, true);
			builder.InsertDocument(extractDoc, ImportFormatMode.KeepSourceFormatting);



		}
		catch (Exception ex)
		{

		}
	}
	destinationDocument.Save(destinationFileName);
}
