Dear Team,
We need to extract part figures from word document. Please find the attached input and expected output document.
Input : input.zip (28.5 KB)
Current Output : Current OP.zip (28.4 KB)
Expected Output : Expected OP.zip (34.8 KB)
Please provide the solution for above scenarios.
Thanking You.
Thanks for your inquiry. Please use the following code example to get the desired output. Hope this helps you.
Document doc = new Document(MyDir + "PartfigProblem.docx");
doc.updateListLabels();
int i = 1;
ArrayList nodes = new ArrayList();
for (Paragraph paragraph : (Iterable<Paragraph>) doc.getChildNodes(NodeType.PARAGRAPH, true))
{
if(paragraph.toString(SaveFormat.TEXT).trim().startsWith("Figure"))
{
Node previousPara = paragraph.getPreviousSibling();
while (previousPara != null
&& previousPara.getNodeType() == NodeType.PARAGRAPH
&& previousPara.toString(SaveFormat.TEXT).trim().length() == 0)
{
if(previousPara != null)
nodes.add(previousPara);
previousPara = previousPara.getPreviousSibling();
}
if(nodes.size() > 0)
{
//Reverse the node collection.
Collections.reverse(nodes);
//Extract the consecutive shapes and export them into new document
Document dstDoc = new Document();
for (Paragraph para : (Iterable<Paragraph>)nodes)
{
NodeImporter importer = new NodeImporter(doc, dstDoc, ImportFormatMode.KEEP_SOURCE_FORMATTING);
Node newNode = importer.importNode(para, true);
dstDoc.getFirstSection().getBody().appendChild(newNode);
}
//Remove the first empty paragraph
if(dstDoc.getFirstSection().getBody().getFirstParagraph().toString(SaveFormat.TEXT).trim().length() == 0)
dstDoc.getFirstSection().getBody().getFirstParagraph().remove();
dstDoc.save(MyDir + "output"+i+".docx");
i++;
nodes.clear();
}
}
}Thanks for your quick update. Its working fine for some documents. But some of the document part figures are not extracted. I have attached the document for your reference. Please find and give solution for this scenario.

Thank you.
Thanks for your inquiry. We suggest you please read following articles.
Aspose.Words Document Object Model
Extract Selected Content Between Nodes
You can use the same approach shared in my previous post to get the desired output. In your case, you need to iterate over paragraphs and get the previous sibling nodes of paragraph whom text starts with “Figure”. Here is the description of API used in the code example.
Please check Aspose.Words for Java - API Reference.
Thanks for your inquiry. Please give us some time. We will write the code example for your scenario and share it here soon.
Please use the following code example to get the desired output. Hope this helps you.

}Thanks for your support. I will check and update. Before that i have used previous extraction code but they have extract some empty pages and paras. please give solution for this scenario.

We need to remove empty pages and empty paragraphs in extracted output.
Thank you.
Thanks for your inquiry. Please check the following IF condition in the code example shared in my previous post. Please use it in your code to avoid empty documents.
if(dstDoc.getFirstSection().getBody().getFirstParagraph().getChildNodes(NodeType.SHAPE, true).getCount() > 0)
{
