Unable to parse form XML from PDF file

We are attempting to pull the XML(or even just the FORM XML) from the following file but we get an error on the sceen.

Could not execute the test pdf parser activity due to one or more errors:
AsposeWrapper.Asposepdf.reflectedInvokeMethod: AsposeWrapper.Asposewords.acceptAllRevisions() Exception occurred System.IO.IOException: Read pdf error:Trailer is not found. at xeb116a323308e2f7.x7759a935a2782a02.readPdf() at xeb116a323308e2f7.x7759a935a2782a02..ctor(String filename, SByte[] ownerPassword) at Aspose.Pdf.Kit.Form.xedff4d4fd296f454() at Aspose.Pdf.Kit.Form..ctor(String srcFileName) at AsposeWrapper.Asposepdf.extractXML(EntityType context, String sourceFilePathNew)


Thank you for considering Aspose.

Can you please provide your code and let us check it?

Aspose.Pdf.Pdf asposePDF = new Aspose.Pdf.Pdf();

String sourceFilePath="c:\\installers\\test.pdf";

Aspose.Pdf.Kit.Form frm= new Aspose.Pdf.Kit.Form(sourceFilePath);

//Manipulate the paths and files
String sourceFileName = Path.GetFileName(sourceFilePath);

String tempFilePath = Path.Combine(tempDirectory, outputFileName);

//Create a new xml file to contain the content of the pdf.
System.IO.FileStream xmlOutputStream = new FileStream(tempFilePath, FileMode.Create);
//Export all the pdf fields' value into the xml file.


I have tested with Aspose.Pdf.Kit v and was not able to reproduce the error.


Following the upgrade of both PDF and PDF Kit the file is returning XML:

<?xml version="1.0" encoding="utf-8" ?>

<fields />


However, Adobe Acrobat Exports a different file when you export it. Try

Menu item Document:Forms:Export Data looks like the following

How can I extract this XML?

<?xml version="1.0" encoding="UTF-8" ?>

Dear djgilles

Thanks for considering our products!

Please try Form.ExportXml( ) instead of Form.ExportXfdf( ). I would like to remind you that XFDF and XML are two different kinds of data formats.

Best regards.

Changing the call to exportXML gave me the correct XML as you suggested. Thanks!

However, there is another issue. The XML when extracted from Adobe PDF viewer is complete. The Aspose exported version gives the following error.
