@priyanga,

Thanks for your inquiry. Your document contains the GroupShape node. Please use the following code example to get the desired output.

Document doc = new Document(MyDir + "test3.docx");
int i = 1;

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

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

        if (node != null &&  node.getNodeType() == NodeType.PARAGRAPH
                && ((Paragraph)node).getChildNodes(NodeType.GROUP_SHAPE, true).getCount()>0)
        { 
            Document dstDoc = new Document();
            NodeImporter importer = new NodeImporter(doc, dstDoc, ImportFormatMode.KEEP_SOURCE_FORMATTING);
            Node newNode = importer.importNode(node, true);
            dstDoc.getFirstSection().getBody().appendChild(newNode);
            dstDoc.save(MyDir + "output"+i+".docx");
            i++;
        }
    }
}

@priyanga,

Thanks for your inquiry. In this case, you need to get the Fig caption from text box. We shared the code example in following forum link.

@priyanga,

Thanks for your inquiry. Please note that the code example shared in this forum thread will not work for all your cases. First you need to list down all your use cases and then write the code accordingly.

We suggest you please check the code example of document explorer from Aspose.Words for Java examples repository at GitHub. You can check the nodes of imported document in document explorer.

For the shared document, the shapes are in GroupShape. You need to use NodeImporter to export the GroupShape into new document.
