Extract text between paragraphs

priyadharshini · May 19, 2017, 2:30am

Hi team,

With regard to extract content between paragraphs, I am able to get total paragraph count.

My requirement is to get the paragraph index/node of all shapes in docx file.

Hi Priya,

Thanks for your inquiry. The image and chart are imported as Shape node in Aspose.Words DOM. After extracting the contents, please use Document.GetChildNodes method to extract the Shape nodes from the document.

If you want to get the index of specified node, please use NodeCollection.indexOf method.

<pre style=“background-color: rgb(255, 255, 255); font-family: “Courier New”; font-size: 9pt;”>NodeCollection allShapes = doc.getChildNodes(NodeType.SHAPE, true);
int shapeIndex = allShapes.indexOf(shape);

If you still face problem, please share your input document and your desired output. We will then provide you more information about your query along with code.

Hi tahir,

Thank you for the quick response. But I request the immediate paragraph count before and after the shape.

I want to extract the shape (image) and image caption after the shape using paragraph index. Is it possible? We have an urgent requirement with extraction of all shapes with the figure caption. Hence I require paragraph index and not shape index.

Thank you

Priya

tahir.manzoor · May 19, 2017, 12:07pm

Hi Priya,

Thanks for sharing the detail. The figure caption (text after the image) is inside separate Paragraph node. Please use following code example to get the desired output. Hope this helps you.

Document doc = new Document(MyDir + "Bernardo_et_al_RevisedPaper.docx");
int i = 1;
NodeCollection shapes = doc.getChildNodes(NodeType.SHAPE, true);
for (Shape shape : (Iterable) shapes)
{
    if(shape.hasImage() && shape.getParentParagraph().getNextSibling() != null
            && shape.getParentParagraph().getNextSibling().getNodeType() == NodeType.PARAGRAPH)
    {
        if(shape.getParentParagraph().getNextSibling().toString(SaveFormat.TEXT).startsWith("Fig"))
        {System.out.println(shape.getParentParagraph().getNextSibling().toString(SaveFormat.TEXT));
            ArrayList nodes =  extractContent(shape.getParentParagraph(), shape.getParentParagraph().getNextSibling(), true);
	    generateDocument(doc, nodes).save(MyDir + "output "+ i + ".docx");
            i++;
        }
    }
}

Thank you so much Tahir and Aspose.

Aspose always surprises with it’s solutions.

I am very thankful for the quick and timely response.

You people have excellent solution to any problem.

Keep going.

priyadharshini · May 24, 2017, 7:21am

Hi tahir,

I further have a request to delete/remove the extracted content from the source word document to perform further processes.

Can you provide a workaround solution to remove content from start to end node extracted using above code from source word document?

tahir.manzoor · May 24, 2017, 11:39am

Hi Priya,

Thanks for your inquiry. We have noticed that you want to extract the contents from the document and remove them also. We suggest you please bookmark the contents that you want to remove or extract from document.

Following code example shows how to bookmark the contents and remove them. Hope this helps you.

Document doc = new Document(MyDir + "Bernardo_et_al_RevisedPaper.docx");
DocumentBuilder builder = new DocumentBuilder(doc);
int i = 1;
NodeCollection shapes = doc.getChildNodes(NodeType.SHAPE, true);
for (Shape shape : (Iterable) shapes)
{
    if(shape.hasImage() && shape.getParentParagraph().getNextSibling() != null
            && shape.getParentParagraph().getNextSibling().getNodeType() == NodeType.PARAGRAPH)
    {
        if(shape.getParentParagraph().getNextSibling().toString(SaveFormat.TEXT).startsWith("Fig"))
        {
            Paragraph fig = (Paragraph)shape.getParentParagraph().getNextSibling();
            shape.getParentParagraph().insertBefore(new BookmarkStart(doc, "Image_"+i), shape);
            fig.appendChild(new BookmarkEnd(doc, "Image_"+i));
            i++;
        }
    }
}

for(Bookmark bookmark : doc.getRange().getBookmarks())
{
    if(bookmark.getName().startsWith("Image_"))
    {
        bookmark.setText("");
    }
}
doc.save(MyDir + "output.docx");
