iText样式将HTML解析为PDF

Question

I've a problem with iText. 我的iText有问题。

I've followed this link: How to export html page to pdf format? 我点击了以下链接：如何将html页面导出为pdf格式？

My snippet: 我的片段：

    String str = "<html><head><body><div style=\"width:100%;height:100%;\"><h3 style=\"margin-left:5px;margin-top:40px\">First</h3><div style=\"margin-left:15px;margin-top:15px\"><title></title><p>sdasdasd shshshshdffgdfgd</p></div><h3 style=\"margin-left:5px;margin-top:40px\">The dream</h3><div style=\"margin-left:15px;margin-top:15px\"></div></div></body></head></html>";
    String fileNameWithPath = "/Users/cecco/Desktop/pdf2.pdf";


    com.itextpdf.text.Document document =
            new com.itextpdf.text.Document(com.itextpdf.text.PageSize.A4);
    FileOutputStream fos = new FileOutputStream(fileNameWithPath);
    com.itextpdf.text.pdf.PdfWriter pdfWriter =
            com.itextpdf.text.pdf.PdfWriter.getInstance(document, fos);

    document.open();

    document.addAuthor("Myself");
    document.addSubject("My Subject");
    document.addCreationDate();
    document.addTitle("My Title");

    com.itextpdf.text.html.simpleparser.HTMLWorker htmlWorker =
            new com.itextpdf.text.html.simpleparser.HTMLWorker(document);
    htmlWorker.parse(new StringReader(str.toString()));

    document.close();
    fos.close();

and work fine. 工作正常

But tag style into h3 and div aren't considered. 但是不考虑将标签样式添加到h3和div中。

在此处输入图片说明

But if I copy my html into http://htmledit.squarefree.com/ all is correct. 但是，如果我将html复制到http://htmledit.squarefree.com/，则一切正确。

How can I solve this problem? 我怎么解决这个问题？

iText isn't the best Html Parser, but you can use Flying-Saucer for this. iText不是最好的HTML解析器，但是您可以为此使用Flying-Saucer 。 Flying-Saucer is build on top of iText but has a capable Xml / (X)Html parser. Flying-Saucer是在iText之上构建的，但具有功能强大的Xml /（X）Html解析器。 Short: Flying Saucer is perfect if you want html -> Pdf. 简短：如果需要html-> Pdf，飞碟是完美的选择。

Here's how to generate the pdf from your string: 这是从字符串生成pdf的方法：

/*
 * Note: i filled something in the title-tag and fixed the head tag (the whole body-tag was in the head)
 */
String str = "<html><head></head><body><div style=\"width:100%;height:100%;\"><h3 style=\"margin-left:5px;margin-top:40px\">First</h3><div style=\"margin-left:15px;margin-top:15px\"><title>t</title><p>sdasdasd shshshshdffgdfgd</p></div><h3 style=\"margin-left:5px;margin-top:40px\">The dream</h3><div style=\"margin-left:15px;margin-top:15px\"></div></div></body></html>";

OutputStream os = new FileOutputStream(new File("example.pdf"));

ITextRenderer renderer = new ITextRenderer();
renderer.setDocumentFromString(str);
renderer.layout();
renderer.createPDF(os);

os.close();

But: FS supports only valid Html / Xhtml / xml, so make shure it is. 但是： FS仅支持有效的 HTML / Xhtml / xml，因此请确保它是。
