Split document into multiple documents on special character

Hi,
I need help splitting my document into 2 documents at a special character.

My document contains 6 pages.
At the start of every page (not counting the header), a “special line”, with smaller font/white color is located (press CTRL+A to see it) - the line always starts with ¤¤¤

At page 1 the line reads:
¤¤¤D_5_20170118142159768biege_1_FD82449C-10FE-4D21-BF80-2764A01383DA

At page 4 another line is located.

I want to split my documents into 2 documents (with 3 pages in each).
How is this possible?

Hope you can help :slight_smile:


Hi Thomas,

Thanks for your inquiry. Please refer to the following articles:
Find and Repalce
How to Extract Selected Content Between Nodes in a Document

Please use the following code example to split the shared document into two documents. Hope this helps you.

Document doc = new Document(MyDir + "AsposeSplitTest.docx");

DocumentBuilder builder = new DocumentBuilder(doc);

//Find the text and insert a bookmark.

doc.Range.Replace("¤¤¤D_5_20170118142159768biege_1_A3E79C04-783D-4658-ADF7-52177CD9276F", "", new FindReplaceOptions(new FindAndInsertBookmark()));

Bookmark bookmark = doc.Range.Bookmarks["BM_0"];

//Bookmark the contents from start of document to matached node.

builder.MoveToDocumentStart();

builder.StartBookmark("FirstDoc");

builder.MoveToBookmark("BM_0", true, false);

builder.EndBookmark("FirstDoc");

//Bookmark the contents from matached node to the end of document

builder.MoveToBookmark("BM_0", false, true);

builder.StartBookmark("SecondDoc");

builder.MoveToDocumentEnd();

builder.EndBookmark("SecondDoc");

//Split the documebt by extracting the contents between bookmarks

Bookmark DocStart = doc.Range.Bookmarks["FirstDoc"];

Bookmark DocEnd = doc.Range.Bookmarks["SecondDoc"];

//Remove the contents of first part of document

Document dstDoc1 = (Document)doc.Clone(true);

dstDoc1.Range.Bookmarks["FirstDoc"].Text = "";

dstDoc1.Save(MyDir + "First Document.docx");

//Remove the contents of second part of document

Document dstDoc2 = (Document)doc.Clone(true);

dstDoc2.Range.Bookmarks["SecondDoc"].Text = "";

dstDoc2.Save(MyDir + "Second Document.docx");

public class FindAndInsertBookmark : IReplacingCallback

{

int i;

ReplaceAction IReplacingCallback.Replacing(ReplacingArgs e)

{

Paragraph para = (Paragraph)e.MatchNode.ParentNode;

DocumentBuilder builder = new DocumentBuilder((Document)e.MatchNode.Document);

builder.MoveTo(e.MatchNode);

builder.StartBookmark("BM_"+i);

builder.EndBookmark("BM_" + i);

i++;

// Signal to the replace engine to do nothing

return ReplaceAction.Skip;

}

}

Hi,
Thanks for the example! :slight_smile:
I have a couple of things:

1) Instead of splitting on the whole “¤¤¤D_5_20170118142159768biege_1_A3E79C04-783D-4658-ADF7-52177CD9276F” string - I need only to split on "¤¤¤"

Im gussing this is enough?:
doc.Range.Replace(“¤¤¤”, “”, new FindReplaceOptions(new FindAndInsertBookmark()));

2) The “Second document” contains 4 pages (a blank one) - how can this be fixed, so both documents only contain the needed 3 pages

3) I have documents with more than 2 pages (3,4,…100 maybe)
I have attached another test-document which should be split into 4 documents (contains 4x ¤¤¤)

Can you make an example doing this? Would be much appreciated :slight_smile:



Hi Thomas,

Please use the following code example to achieve your requirements. This code example does the followings:

1) Find the text ¤¤¤ and insert bookmark with name start with "BM_".
2) Extract the contents between two bookmarks e.g. "BM_0" and "BM_1"

Please get the code of GenerateDocument and ExtractContent methods from Aspose.Words for .NET examples repository at GitHub.

Document doc = new Document(MyDir + "AsposeSplitTest2.docx");

DocumentBuilder builder = new DocumentBuilder(doc);

//Find the text and insert a bookmark.

doc.Range.Replace("¤¤¤", "", new FindReplaceOptions(new FindAndInsertBookmark()));

ArrayList bookmarks = new ArrayList();

foreach (Bookmark bookmark in doc.Range.Bookmarks)

{

if (bookmark.Name.StartsWith("BM_"))

bookmarks.Add(bookmark.Name);

}

builder.MoveToDocumentEnd();

builder.StartBookmark("BM_" + bookmarks.Count + 1);

builder.EndBookmark("BM_" + bookmarks.Count + 1);

bookmarks.Add("BM_" + bookmarks.Count + 1);

for (int i = 0; i < bookmarks.Count - 1; i++)

{

BookmarkStart bookmarkStart = doc.Range.Bookmarks[bookmarks[i].ToString()].BookmarkStart;

BookmarkStart bookmarkEnd = doc.Range.Bookmarks[bookmarks[i + 1].ToString()].BookmarkStart;

ArrayList extractedNodes = Common.ExtractContent(bookmarkStart, bookmarkEnd, false);

Document doc2 = Common.GenerateDocument(doc, extractedNodes);

doc2.Save(MyDir + "output" + i + ".docx");

}


If you want to remove the last empty page of document, please use following code example.

Document doc = new Document(MyDir + "input.docx");

if (doc.LastSection.Body.Paragraphs.Count == 1 && doc.LastSection.Body.LastParagraph.ToString(SaveFormat.Text).Trim() == "")

doc.LastSection.Remove();

//get last section

Section lastSect = doc.LastSection;

//Remove empty paragraphs from the end of the document

while (string.IsNullOrEmpty(lastSect.Body.LastParagraph.ToString(SaveFormat.Text).Trim()))

{

lastSect.Body.LastParagraph.Remove();

}

doc.Save(MyDir + "Out.docx");

sanath-sample-test.zip (49.5 KB)

I tried the above solution with the word file attached inside the zip, i actually want to split the document from the word “Country=” to till the next word “Country=” appears so ideally document need to split to 4 separate documents

string dataDir = RunExamples.GetDataDir_WorkingWithDocument();
string fileName = “sanath-sample-test.docx”;
Document doc = new Document(dataDir + fileName);

        DocumentBuilder builder = new DocumentBuilder(doc);
        doc.Range.Replace("Country=", "", new FindReplaceOptions(new FindAndInsertBookmark()));
        ArrayList bookmarks = new ArrayList();
        foreach (Bookmark bookmark in doc.Range.Bookmarks)
        {
            if (bookmark.Name.StartsWith("BM_"))
                bookmarks.Add(bookmark.Name);
        }
        builder.MoveToDocumentEnd();
        builder.StartBookmark("BM_" + bookmarks.Count + 1);
        builder.EndBookmark("BM_" + bookmarks.Count + 1);
        bookmarks.Add("BM_" + bookmarks.Count + 1);
        for (int i = 0; i < bookmarks.Count; i++)
        {
            BookmarkStart bookmarkStart = doc.Range.Bookmarks[bookmarks[i].ToString()].BookmarkStart;
            BookmarkStart bookmarkEnd = doc.Range.Bookmarks[bookmarks[i + 1].ToString()].BookmarkStart;
            ArrayList extractedNodes = Common.ExtractContent(bookmarkStart, bookmarkEnd, false);
            Document doc2 = Common.GenerateDocument(doc, extractedNodes);
            doc2.Save(dataDir + "output" + i + ".docx");
        }

    }

@sanathjs

Please add space between “Country” and “=” as shown below to get the desired output.

doc.Range.Replace(“Country =”, “”, new FindReplaceOptions(new FindAndInsertBookmark()));

Thanks for the quick reply, much appreciated your solution is working for me now :slight_smile:

@sanathjs

Please feel free to ask if you have any question about Aspose.Words, we will be happy to help you.

When the document is split it is loosing it’s original style inside (like paragraph fonts etc… are changed) how to retain the original style of the document? or how to retain the original word template and split (like attach the same template even to the splited documents).

@sanathjs

Please ZIP and attach the screenshots of problematic sections of output document along with problematic and expected output documents. We will then provide your more information about your query.

test.zip (326.7 KB)

hi @tahir.manzoor,

I have attached the screen shot of original file before split and file after splitting also i have attached the file used to split and splitted files, you may notice the changes in font for paragraph after splitting please have a look at let me know the solution earliest as possible.

@sanathjs

We are investigating your issue and will get back to you soon.

@sanathjs

The style name of shared paragraph is not properly set in your input document. You can check it by unzipping the document in document.xml. Please open the document in MS Word and clear the formatting. MS Word creates new style for the shared paragraph.

Please use the following modified GenerateDocument method to get the desired output.

public static Document GenerateDocument(Document srcDoc, ArrayList nodes)
{
    Document dstDoc = srcDoc.Clone();

    dstDoc.RemoveAllChildren();
    dstDoc.EnsureMinimum();
    // Import each node from the list into the new document. Keep the original formatting of the node.
    NodeImporter importer = new NodeImporter(srcDoc, dstDoc, ImportFormatMode.KeepSourceFormatting);

    foreach (Node node in nodes)
    {
        Node importNode = importer.ImportNode(node, true);
        dstDoc.FirstSection.Body.AppendChild(importNode);
    }

    // Return the generated document.
    return dstDoc;
}
