Hello Bruno,

 

Topic: Creating a PDF file using String object with HTML content

 

I am getting an error (see below) when I parse my HTML string using HTMLWorker

 

ERROR

--------------

java.lang.IllegalArgumentException: The number of columns in PdfPTable constructor must be greater than zero.

          at com.lowagie.text.pdf.PdfPTable.<init>(Unknown Source)

          at com.lowagie.text.html.simpleparser.IncTable.buildTable(Unknown Source)

          at com.lowagie.text.html.simpleparser.HTMLWorker.parse(Unknown Source)

          at PDF.main(PDF.java:25)

CODE

--------------

Transform trans = new Transform();

String htmlOP = trans.transform("D:\\work\\SEACR.xsl","D:\\work\\SEACR.xml");

System.out.println(htmlOP);

StringReader strReader = new StringReader(htmlOP);

PdfWriter.getInstance(document, new FileOutputStream("test.pdf"));

document.open();

document.resetPageCount();

//document.add(new Paragraph("Hi, this is your PDF file!"));

HTMLWorker html = new HTMLWorker(document);

html.parse(strReader);

--------------

 

My AIM is to create a PDF file with the html string “htmlOP”. Thank you very much.

 

Regards

Subject: Creating a PDF file using String object with HTML content

 

Dear Users,

 

I have transformed my XML and XSL to a StringWriter object like this

 

// Transformation code

StringWriter writer = new StringWriter();

transformer.transform(new StreamSource(xml), new StreamResult(writer));

 

String str_with_html_tags = writer.toString();

 

The result of the transformation i.e “str_with_html_tags” is then passed to the PDF generation code.

 

// PDF Generation code

PdfWriter.getInstance(document, new FileOutputStream("filename.pdf"));

document.open();

document.add(str_with_html_tags);

 

 

But as a result when I open the PDF document I could see text with all HTML tags embedded in it.

 

My Questions.

 

  1. Why the PDFWriter doesn’t understand the HTML tags and format the text accordingly in the PDF document?
  2. Is there any other way to generate a PDF document from a String object having HTML tags embedded in it?

 

Note: I am using HTML in my XSL document.

 

Please ask me if you have any questions.

 

Thanks and regards,

 

Mazhar Shaikh
