Hi Tahir,

I have shared Input document and sample java code without compilation error.
Here we are saving extracted data in database based on Heading 1, so I am not going to attach output word file.
If you can see in below code it’s not going find Heading 1 from input document in if condition.

// Not getting all heading 1 for input document
if (para.getParagraphFormat().isHeading() && para.getParagraphFormat().getStyle().getName().equals(Constants.HEADING_STYLE)) {
System.out.println("Document heading 1 :: " + para.getText());
Paragraph paragraph = new Paragraph(doc);
para.getParentNode().insertBefore(paragraph, para);
builder.moveTo(paragraph);
builder.startBookmark(Constants.BOOKMARK_NAME + i);
builder.endBookmark(Constants.BOOKMARK_NAME + i);

				i++;
			}

Expected output: There are 9 Heading 1 in attached document, so It should go IF block 9 times.

Your input document contains the eight paragraph with “Heading 1” style. You shared in “9 heading 1.png” that following text has heading style. However, its style is not “Heading 1”. Please check the attached image for detail. Style Heading.png (60.2 KB)

Content of the AIR6516 RSA Model

Hi Tahir,

When you run attached java program with “AIR6516.docx”, it’s going to extract only 4 Heading 1 style instead of 8.

Please check and update me, If I missed something.

Thank you!

Could you please share the steps that you are using at your end? We will investigate the issue and provide you more information on it.

Hi Tahir,

I have check existing code and found “checkLicence()” method is not placed at right location.
