Issue with Bookmark range

Aspose.Words Product Family
#1

I am having an issue with exporting a bookmark from one document to another. If you look at the attached Word document, you will see that I am bookmarking all of the 1st line and only part of the 2nd line. But when I export the bookmark to the target document, all of the 2nd line gets copied over, even though part of the 2nd line is not part of the bookmark (namely: "THIS SENTENCE IS NOT A PART OF THE BOOKMARK.").

If I remove the first line, then it works fine, but not as is. Any suggestions here?

Thanks in advance!

Here is my code:

// This method is used to export a bookmark to a document.
private void ExportBookmarkToDocument(Bookmark bookmark, ref Aspose.Words.Document targetDocument)
{
// Get node that containd BookmarkStart and BookmarkEnd
Node currentNode = bookmark.BookmarkStart.ParentNode;
Node endNode = bookmark.BookmarkEnd.ParentNode;

// if bookmarkStart and bookmarkEnd are children of different nodes, then import nodes between parent nodes of bookmark start and bookmark end
if (currentNode != endNode)
{
// import nodes between BookmarkStart and BookmarkEnd Parent nodes
while (currentNode != endNode)
{
Node newNode = targetDocument.ImportNode(currentNode, true, ImportFormatMode.KeepSourceFormatting);
targetDocument.FirstSection.Body.AppendChild(newNode);
currentNode = currentNode.NextSibling;
}

targetDocument.FirstSection.Body.AppendChild(targetDocument.ImportNode(endNode, true, ImportFormatMode.KeepSourceFormatting));
}

// else import nodes between bookmark start and bookmark end
else
{
currentNode = bookmark.BookmarkStart.NextSibling;

// import nodes between BookmarkStart and BookmarkEnd
while (currentNode != bookmark.BookmarkEnd)
{
Node newNode = targetDocument.ImportNode(currentNode, true, ImportFormatMode.KeepSourceFormatting);
targetDocument.FirstSection.Body.FirstParagraph.AppendChild(newNode);
currentNode = currentNode.NextSibling;
}
}
}

Hi<?xml:namespace prefix = o ns = "urn:schemas-microsoft-com:office:office" />

Thanks for your inquiry. In your code you import BookmarkStart.ParentNode and BookmarkEnd.ParentNode. Parent node of Bookmark end is whole paragraph and not sentence. So you should import only part of BookmarkEnd parent paragraph. You can open your document using DocumentBuilder (Aspose.Words demo app) to see its structure.

Best regards.

Alexey,

Thanks for the reply, and I'll take a stab at it, though one thing about your statement is a little confusing for me: "So you should import only part of BookmarkEnd parent paragraph". My question here is: how do I extract the part that I need, specifically the content within the bookmark?

Also note that the code that I have included in this post is pretty much a verbatim copy of code you sent me early to export a bookmark. Is the code simply incomplete, or not geared towards the task I have in mind.

In general I have found Aspose very useful and easy to use, but Bookmarks has been the one exception to that rule. E.g., in the Microsoft Primary Interop Assemblies, you can copy the range of the whole bookmark in a single method call (Bookmark.Range.Copy()) and paste it in the next line using Document.Content.Paste. So it surprised me a little when I found that there was no easy way to just copy the whole bookmark range and paste it in another document (or is there???.. or any plans to implement that??).

Thanks again!

Hi<?xml:namespace prefix = o ns = "urn:schemas-microsoft-com:office:office" />

Thanks fro your inquiry. Actually this code was just example how you can achieve this.

Please try using the following code:

// This method is used to export a bookmark to a document.

private void ExportBookmarkToDocument(Bookmark bookmark, ref Aspose.Words.Document targetDocument)

{

// Get node that containd BookmarkStart and BookmarkEnd

Node currentNode = bookmark.BookmarkStart.ParentNode;

Node endNode = bookmark.BookmarkEnd.ParentNode;

// if bookmarkStart and bookmarkEnd are children of different nodes, then import nodes between parent nodes of bookmark start and bookmark end

if (currentNode != endNode)

{

//Import part of first paragraph if this is needed

if (!(currentNode as CompositeNode).FirstChild.Equals(bookmark.BookmarkStart))

{

CompositeNode firstNode = (CompositeNode)targetDocument.ImportNode(currentNode, true, ImportFormatMode.KeepSourceFormatting);

while (firstNode.HasChildNodes)

{

if (firstNode.FirstChild.NodeType != NodeType.BookmarkStart)

firstNode.FirstChild.Remove();

else if ((firstNode.FirstChild as BookmarkStart).Name != bookmark.Name)

firstNode.FirstChild.Remove();

else

break;

}

targetDocument.FirstSection.Body.AppendChild(firstNode);

currentNode = currentNode.NextSibling;

}

// import nodes between BookmarkStart and BookmarkEnd Parent nodes

while (currentNode != endNode)

{

Node newNode = targetDocument.ImportNode(currentNode, true, ImportFormatMode.KeepSourceFormatting);

targetDocument.FirstSection.Body.AppendChild(newNode);

currentNode = currentNode.NextSibling;

}

if ((endNode as CompositeNode).LastChild.Equals(bookmark.BookmarkEnd))

{

targetDocument.FirstSection.Body.AppendChild(targetDocument.ImportNode(endNode, true, ImportFormatMode.KeepSourceFormatting));

}

//import part of last paragraph if this is needed

else

{

CompositeNode lastNode = (CompositeNode)targetDocument.ImportNode(endNode, true, ImportFormatMode.KeepSourceFormatting);

while (lastNode.HasChildNodes)

{

if (lastNode.LastChild.NodeType != NodeType.BookmarkEnd)

lastNode.LastChild.Remove();

else if ((lastNode.LastChild as BookmarkEnd).Name != bookmark.Name)

lastNode.LastChild.Remove();

else

break;

}

targetDocument.FirstSection.Body.AppendChild(lastNode);

}

}

// else import nodes between bookmark start and bookmark end

else

{

currentNode = bookmark.BookmarkStart.NextSibling;

// import nodes between BookmarkStart and BookmarkEnd

while (currentNode != bookmark.BookmarkEnd)

{

Node newNode = targetDocument.ImportNode(currentNode, true, ImportFormatMode.KeepSourceFormatting);

targetDocument.FirstSection.Body.FirstParagraph.AppendChild(newNode);

currentNode = currentNode.NextSibling;

}

}

}

Hope this helps.

Best regards.

That did the trick, thanks!

As a recommendation to the design/marketing team, I think this sort of functionality should be wrapped in a method as a standard part of the API; not specifically the method listed in this post (ExportBookmarkToDocument), but maybe a a method to copy/fetch the entire bookmark range and another one to copy/append it another document. So for example, this how I might expect to re-write my code this if this recommendation were to be implemented:

private void ExportBookmarkToDocument(Bookmark bookmark, ref Aspose.Words.Document targetDocument)<?xml:namespace prefix = o ns = "urn:schemas-microsoft-com:office:office" />

{
newNode = bookmark.Range;
targetDocument.FirstSection.Body.FirstParagraph.AppendChild(newNode);
}

... or something to that effect. I think it's great that Aspose has the flexibility in to do what you did in the code you showed me, but this could be taken a step further and encapsulated for more ease of use; I don't feel someone should have to do all this just to copy a bookmark. Just a suggestion though.

Thank you!

Hello Jafar!<?xml:namespace prefix = o ns = "urn:schemas-microsoft-com:office:office" />

Thank you for your thoughtful feedback. We’ll consider improvements allowing operation on a bookmark as a whole. But this task is not so frequent so we cannot give it high priority.

I have created a new issue in our defect database:

#5299 – Allow operation on bookmark as a whole

Also there could be interesting for you to track this issue:

#502 – Allow to get and set bookmark text when start and end have different grand parents

Have a nice day!

Sounds good, thanks!

One final question: How track/view the issues you've listed above?

Thank you.
