public class D04_ParseHtmlCss {

    public static final String HTML = "src/walden.html";
    public static final String CSS = "src/walden.css";
    public static final String DEST = "src/xmlworker/hasil.pdf";

    public void createPdf(String file) throws IOException, DocumentException {
        // step 1
        Document document = new Document();

        // step 2
        PdfWriter writer = PdfWriter.getInstance(document, new FileOutputStream(file));
        writer.setInitialLeading(12.5f);

        // step 3
        document.open();

        // step 4

        // CSS
        CSSResolver cssResolver = new StyleAttrCSSResolver();
        CssFile cssFile = XMLWorkerHelper.getCSS(new FileInputStream(CSS));
        cssResolver.addCss(cssFile);

        // HTML
        HtmlPipelineContext htmlContext = new HtmlPipelineContext(null);
        htmlContext.setTagFactory(Tags.getHtmlTagProcessorFactory());

        // Pipelines
        PdfWriterPipeline pdf = new PdfWriterPipeline(document, writer);
        HtmlPipeline html = new HtmlPipeline(htmlContext, pdf);
        CssResolverPipeline css = new CssResolverPipeline(cssResolver, html);

        // XML Worker
        XMLWorker worker = new XMLWorker(css, true);
        XMLParser p = new XMLParser(worker);
        p.parse(new FileInputStream(HTML));

        // step 5
        document.close();
    }

    /**
     * Main method
     */
    public static void main(String[] args) throws IOException, DocumentException {
        File file = new File(DEST);
        file.getParentFile().mkdirs();
        new D04_ParseHtmlCss().createPdf(DEST);
    }
