Remove Extra Line Break while Inserting HTML in Word Document after a Hidden Character using Java Code

Hi,
While creating a document, I am adding a hidden word (using builder.write()) , then I am inserting a html string (using builder.insertHtml()) and after that again i am adding an another hidden word with builder.write(). I want the html to start just after the hidden word (without any line break ) and the ending hidden character also have to bind with the html end (No need of any line space after the html content). This making lot of unwanted line break.

I am attaching My sample code input and output below.

It’s a very critical issue for me. So please help me to find out a solution ASAP.

Thank You

@Gptrnt,

This seems to be an expected behavior. But, you can workaround this problem by using the following code:

public static Document generateDocument(Item item) throws Exception {
    // Create a blank document.
    Document dstDoc = new Document();
//        dstDoc.protect(ProtectionType.READ_ONLY);
    // Creating builder for the document
    DocumentBuilder builder = new DocumentBuilder(dstDoc);
    double tokenSize = builder.getFont().getSize();
    Color tokenColor = builder.getParagraphFormat().getStyle().getFont().getColor();
    String tokenFontName = builder.getFont().getName();
    int tokenParagraphAlignment = builder.getParagraphFormat().getAlignment();
    boolean isTokenInItalicFont = builder.getFont().getItalic();
    Style tokenStyle = builder.getParagraphFormat().getStyle();
    item.getItemDetails().forEach(details -> {
        try {
            builder.getFont().setBold(true);
            builder.getParagraphFormat().setAlignment(ParagraphAlignment.LEFT);
            builder.getParagraphFormat().setKeepTogether(true);
            String title = null;
            if (details.getTitle() != null) {
                String serialNum = details.getSlNo() + ": ";
                title = serialNum + details.getTitle();
            }
            builder.getParagraphFormat().setStyleIdentifier(StyleIdentifier.HEADING_1);
            builder.getParagraphFormat().getStyle().getFont().setColor(tokenColor);
            builder.getFont().setSize(tokenSize);
            builder.getParagraphFormat().getStyle().getFont().setUnderline(Underline.NONE);
            builder.getFont().setName(tokenFontName);
            builder.getParagraphFormat().setAlignment(tokenParagraphAlignment);
            builder.getFont().setItalic(isTokenInItalicFont);
            builder.getParagraphFormat().setSpaceAfterAuto(true);
            addHiddenWord(builder, details.getSlNo(), false, Constant.HIDDEN_TITLE_KEY);
            builder.write(title);
            addHiddenWord(builder, details.getSlNo(), true, Constant.HIDDEN_TITLE_KEY);

            builder.getParagraphFormat().setStyle(tokenStyle);
            builder.getFont().setBold(false);
            builder.getFont().setUnderline(Underline.NONE);
            builder.getParagraphFormat().setSpaceAfterAuto(false);

            if (details.getNote() != null) {
                addHiddenWord(builder, details.getSlNo(), false, Constant.HIDDEN_NOTE_KEY);
                // builder.insertHtml(details.getNote().trim() + "</p>", Constant.USE_BUILDER_FORMATTING);

                String htmlString = details.getNote().trim();
                if (htmlString != "") {
                    ByteArrayInputStream bais = new ByteArrayInputStream(htmlString.getBytes());
                    Document tempDoc = new Document(bais);
                    builder.insertDocument(tempDoc, ImportFormatMode.KEEP_SOURCE_FORMATTING);
                }

                addHiddenWord(builder, details.getSlNo(), true, Constant.HIDDEN_NOTE_KEY);
            }
            addHiddenWord(builder, details.getSlNo(), false, Constant.HIDDEN_DESCRIPTION_KEY);
            builder.insertHtml((details.getDescription() != null ? details.getDescription().trim() : Constant.ONE_SPACE) + "</p>", Constant.USE_BUILDER_FORMATTING);
            addHiddenWord(builder, details.getSlNo(), true, Constant.HIDDEN_DESCRIPTION_KEY);

            builder.getFont().setUnderline(Underline.NONE);
            builder.getParagraphFormat().setSpaceAfterAuto(false);
        } catch (Exception e) {
            System.out.println("Error while insert html to the doc");
        }
    });
    return dstDoc;
}

Hi awais,

I tried with your solution. I am also using ckeditor html content for download in default(If the user not import the word). That time this solution getting issue. I am attaching the issued output along with sample code to reproduce(ckeditor content hard coded inside the code.). and expected output.

SampleIssue.zip (591.1 KB)

For removing thus issue, I used a solution(commented in the above uploaded sample code)

    if (!htmlString.startsWith("<html>")){
                Document tempDoc = new Document();
                DocumentBuilder tempBuilder = new DocumentBuilder(tempDoc);
                tempBuilder.insertHtml(htmlString);
                htmlString = tempDoc.toString(saveOption);
     }

But with this code content is printing but at the end getting one extra enter(line break). Please help me with an optimized solution.

Thank you

@Gptrnt,

Please try specifying the HTML Load Options and then load the HTML document/string. Here is sample code:

...
...
if (htmlString != "") {
    ByteArrayInputStream bais = new ByteArrayInputStream(htmlString.getBytes());
    LoadOptions opts = new LoadOptions();
    opts.setLoadFormat(LoadFormat.HTML);
    Document tempDoc = new Document(bais, opts);
    builder.insertDocument(tempDoc, ImportFormatMode.KEEP_SOURCE_FORMATTING);
}
...
...

Hope, this helps.

@Gptrnt,

As can be seen in following screenshot, the formatting is applied via Style and by using “direct attributes”:

So, the reason is that you set both the Style and Paragraph properties, therefore some of the style properties are overridden. To avoid this, you should simply either use only style or only paragraph properties. We suggest to use only Style, remove all this ‘builder.getFont().setSize(tokenSize);’ and leave only ‘builder.getParagraphFormat().setStyleIdentifier(StyleIdentifier.HEADING_1);’. It should work as expected.

Also some code looks a bit strange, and you may want to remove it. For example:

Color tokenColor = builder.getParagraphFormat().getStyle().getFont().getColor();
skipped
builder.getParagraphFormat().getStyle().getFont().setColor(tokenColor);

We are planning to close linked issue (WORDSNET-20644) with “Not a Bug” status.

P.S. Please note that Formatting is applied on a few different levels. For example, let’s consider formatting of simple text. Text in documents is represented by Run element and a Run can only be a child of a Paragraph. You can apply formatting 1) to Run nodes by using Styles e.g. a Glyph Style, 2) to the parent of those Run nodes i.e. a Paragraph node (possibly via paragraph Styles) and 3) you can also apply ‘direct formatting’ to Run nodes by using Run attributes (Font). In this case the Run will inherit formatting of Paragraph Style, a Glyph Style and then direct formatting.
