@akshayapria,

Thanks for your inquiry. In this scenario, your document contains the GroupShape. Please use following code example to extract the GroupShape. Hope this helps you.

Document doc = new Document(MyDir + "test.doc");
int i = 1;
NodeCollection paragraphs = doc.getChildNodes(NodeType.PARAGRAPH, true);

for (Node paragraph : (Iterable<Paragraph>) paragraphs)
{
    if(paragraph.toString(SaveFormat.TEXT).trim().startsWith("Fig"))
    {
        Node node = paragraph.previousPreOrder(doc);
        while (node != null &&  node.getNodeType() != NodeType.GROUP_SHAPE && node.getNodeType() != NodeType.BODY)
        {
            node = node.previousPreOrder(doc);
        }
        if(node != null &&  node.getNodeType() == NodeType.GROUP_SHAPE)
        {
            Document dstDoc = new Document();
            NodeImporter importer = new NodeImporter(doc, dstDoc, ImportFormatMode.KEEP_SOURCE_FORMATTING);
            Node newNode = importer.importNode(node, true);
            dstDoc.getFirstSection().getBody().getFirstParagraph().appendChild(newNode);
            dstDoc.save(MyDir + "output"+i+".docx");
            i++;
            continue;
        }
    }
}

@akshayapria,

Thanks for your inquiry. Please use following code example to get the desired output.

Document doc = new Document(MyDir + "test.doc");
int i = 1;
java.util.List<Node> al = new ArrayList<Node>();
Set<Node> hs = new HashSet<>();

NodeCollection paragraphs = doc.getChildNodes(NodeType.PARAGRAPH, true);

for (Node paragraph : (Iterable<Paragraph>) paragraphs)
{
    if(paragraph.toString(SaveFormat.TEXT).trim().contains("Fig"))
    {
        Node node = paragraph.previousPreOrder(doc);

        while (node != null &&  node.getNodeType() != NodeType.GROUP_SHAPE && node.getNodeType() != NodeType.BODY)
        {
            node = node.previousPreOrder(doc);
        }
        if(node != null &&  node.getNodeType() == NodeType.GROUP_SHAPE)
        {
            al.add(node);
        }
    }
}

hs.addAll(al);
al.clear();
al.addAll(hs);

for(Node node : al)
{
    System.out.println(node);
    Document dstDoc = new Document();
    NodeImporter importer = new NodeImporter(doc, dstDoc, ImportFormatMode.KEEP_SOURCE_FORMATTING);
    Node newNode = importer.importNode(node, true);
    dstDoc.getFirstSection().getBody().getFirstParagraph().appendChild(newNode);
    dstDoc.save(MyDir + "output"+i+".docx");
    i++;
}

@akshayapria,

Thanks for your inquiry. Your input document contains eight group shapes. The code example shared in my previous post generates the correct output. We have attached the output documents with this post for your kind reference. output docs.zip (158.9 KB)

Please make sure that you are using the same code and latest version of Aspose.Words for Java 17.11.

@akshayapria,

Thanks for your inquiry.

In this case, we suggest you following solution.

  1. Iterate through all paragraphs.
  2. If paragraph starts with text “Fig”, get the previous nodes from this paragaph until it is not shape node into ArrayList. In this case, please also add paragraphs into ArrayList that have text (a), (b) etc.
  3. Please use NodeImporter to import the extracted nodes into new document.

Please refer to the following article.
