PDF.BindXML creating empty/blank PDF file


#1

Hi


I am trying to create a PDF file using the PDF.BindXml method. I am passing it two Memory streams, one for the XML file and the other for the XSLT. When I run the code I do not receive any errors and it creates a PDF file. However, that PDF file that it creates is just a blank document. Below is the code I am running and I have also attached a zip file with the XML and XSLT files. I am currently using the Aspose 8.5.0 version.

Code:
private void ConvertXmlXsltToPDF(MemoryStream msXml, MemoryStream msXslt)
{
msXslt.Position = 0;
msXml.Position = 0;

aGenPDF.Pdf pdfNew = new aGenPDF.Pdf();
pdfNew.BindXML(msXml, msXslt);

pdfNew.Save(@“C:\temp\xml\test.pdf”);
}


Thanks

Arthur

Hi Arthur,


Thanks for your patience.

We have further investigated the issue PDFNEWNET-35985 reported earlier and it does not seem to be an issue with Aspose.Pdf for .NET. Please note that BindXML expects that summery XML that it will get after applying XSLT to that supplied XML, will contain special tags related to PDF document object model. Something like this XML must be generated after translation.

However, as we can see from set of sample files, customer's set of XML+XSLT generates HTML, that will not (and should not) be correctly processed with BingXML method. Please get HTML from XML + XSLT and then use BindHTML method to get desired results.

Hi codewarior,

As per my requirement I have to take data from XML and use custom XSL to generate PDF Which I am able to do with first approach but not using second approach.

I have tried as below post

To generate the PDF, I have tried 2 approaches-

  1. Transformed XML data with XSL and converted into HTML then Using Aspose.HTML, converted HTML to PDF(It’s working as expected using same .xml and .xsl files)

  2. When I am trying to use Aspose.PDF please check below code. Pdf is generating and is not opening because it’s blank pdf. Even I have used same xml which suggested by Farhan (https://github.com/aspose-pdf/Aspose.PDF-for-.NET/blob/master/Examples/Examples.xml)
    and try to generate PDF using XML only it’s generating BLANK PDF.

If XML schema is not proper in attached snapshot please share the updated valid XML so I can use below code for my requirement.2.PNG (8.6 KB)

Document pdf = new Document();

        using (FileStream fs1 = new FileStream(xmlpath + "Examples.xml", FileMode.Open))
        using (FileStream fs2 = new FileStream(xmlpath + "Examples.xsl", FileMode.Open))
        {
            // Bind the XML file
            pdf.BindXml(fs1, fs2);
            // Save the resultant PDF
            pdf.Save(xmlpath + "Examples.pdf");
        }

I am achieving requirement using first approach but I don’t have ASPOSE.Html lic but I have for ASPOSE.Pdf.lic

Thanks in advance
