Hi,

I want to convert a word document into HTML string and store it in a DB. This stored Html string will show in UI. And also have to insert in another word document. While converting to Html, the numbered and bullet list is not coming properly. And some other issues also. So can you please help to solve the issue.
Attaching the input doc

Regarding the exception you are facing, we suggest you please use the HtmlSaveOptions as shown below.

HtmlSaveOptions options = new HtmlSaveOptions();
options.setSaveFormat(SaveFormat.HTML);
options.setExportImagesAsBase64(true);

html[0] += node.toString(options);

Regarding the list items issue, please use the following code example.

Document outputDocument = new Document();
outputDocument.removeAllChildren();

Document document = new Document(MyDir + "input_doc.docx");
HtmlSaveOptions options = new HtmlSaveOptions();
options.setSaveFormat(SaveFormat.HTML);
options.setExportImagesAsBase64(true);

Document pdfDocument = new Document();
DocumentBuilder builder = new DocumentBuilder(pdfDocument);
//  Get Paragraph Collection
NodeCollection<Paragraph> paragraphColl = document.getChildNodes(NodeType.PARAGRAPH, true);
List<Paragraph> headings = getHeadingFromParagraph(paragraphColl);
ArrayList<Node>  extractedNodes = new ArrayList();
List<String> html = new ArrayList<>();
for (int i=0;i<headings.size();i++){
    Paragraph startNode = headings.get(i);
    if(headings.size()> (i + 1)){
        Paragraph endNode = headings.get(i + 1);
        ArrayList<Node> nodes = Extract_contents.extractContent(startNode,endNode,false);
        Document dstHTML = Extract_contents.generateDocument(document, nodes);
        html.add(dstHTML.toString(options));
        //html.add(convertNodeToHtmlStr(nodes));
    }else{

    }
}
outputDocument = generateDocument(html);
outputDocument.save(MyDir + "20.4.docx", SaveFormat.DOCX);

Hi,

In my document may contains the hidden contents(it could be paragraph, table, etc…).I wants to identify each hidden item and have to extract it. I am using java, I tried with the code specified in the documentation, but unfortunately I am getting error with the code. Can you please tell me the proper code.

@Gptrnt

Please iterate over Run nodes as shown below and remove the hidden formatting of text. Hope this helps you.

Document doc = new Document(MyDir + "in.docx");
for (Run  run : (Iterable<Run>) doc.getChildNodes(NodeType.RUN, true))
{
    if(run.getFont().getHidden())
        run.getFont().setHidden(false);
}

HtmlSaveOptions options = new HtmlSaveOptions();
options.setSaveFormat(SaveFormat.HTML);
options.setExportImagesAsBase64(true);
doc.save(MyDir + "output.html", options);
