使用带有CSS的iText API时无法生成PDF

Question

我正在尝试从具有CSS的HTML生成pdf。

以下是代码段

        Document document = new Document();
        PdfWriter pdfWriter = PdfWriter.getInstance(document, new FileOutputStream(outFileName));

        document.open();

        String htmlTxt = FileUtils.readFileToString(new File(dirPath + inpFileName), "UTF-8");
        ByteArrayInputStream fis = new ByteArrayInputStream(htmlTxt.getBytes("UTF-8"));
        XMLWorkerHelper worker = XMLWorkerHelper.getInstance();
        // worker.parseXHtml(pdfWriter, document, fis);

        worker.parseXHtml(pdfWriter, document, new FileInputStream(dirPath + inpFileName),
                new FileInputStream(CSS));

        // close the document
        document.close();
        // close the writer
        pdfWriter.close();

我尝试使用生成pdf worker.parseXHtml（pdfWriter，document，fis）; PDF没有

生成

工作正常然后使​​用 worker.parseXHtml（pdfWriter，document，new FileInputStream（dirPath + inpFileName），new FileInputStream（CSS））; 在这种情况下，pdf会生成但没有任何内容。

我还尝试了如iText Parse HTML with CSS Example

中建议的那样使用CSS解析器

重要说明 - HTML已从jTidy API生成。 这是HTML和CSS文件
