XHTMLImporterImpl.convert() can't handle converting custom data attributes for br tags to xhtml

[JamaicanFriedChicken]

I have a data attribute that is appended in a <br> tag, for example <br data-suggestion="ef0oraskdmd">, when I am trying to convert it into a xhtml format, it gives me the below error:

ERROR org.docx4j.convert.in.xhtml.XHTMLImporterImpl - org.xml.sax.SAXParseException; lineNumber: 1; columnNumber: 55991; The element type "br" must be terminated by the matching end-tag "</br>"."

When I remove the data attribute data-*, XHTMLImporterImpl is able to convert it to a xhtml format. How can I mitigate this issue? Is there any temporary fix I can implement?

you can try like this,

  private static String preprocessHtml(String htmlContent) {
        Document doc = Jsoup.parse(htmlContent);
        Elements codeElements = doc.select("code");
        Map<String, String> codeReplacements = new HashMap<>();

        // Replace new lines with <br /> in <code> elements
        for (Element codeElement : codeElements) {
            String codeText = codeElement.html().replace("\n", "<br />");
            codeReplacements.put(codeElement.html(), codeText);
        }

        String processedHtml = doc.html();
        for (String key : codeReplacements.keySet()) {
            processedHtml = processedHtml.replace(key, codeReplacements.get(key));
        }

        processedHtml = processedHtml.replaceAll("<img(.*?)>", "<img$1 />");
        processedHtml = processedHtml.replaceAll("<br>", "<br />");
        processedHtml = processedHtml.replaceAll("<hr>", "<hr />");
        return processedHtml;
    }
