This example shows how to export AcroForm data (interactive form data) from a PDF document to XML format.
You can also export the AcroForm data to FDF, XFDF, and TXT formats using the approach described below.
To export AcroForm to XML format:
- load a document containing interactive forms (e.g., from a file path) into the PDF Viewer using the PdfViewer.LoadDocument method;
- call one of the PdfViewerExtensions.Export overloaded methods, for example, with a specified XML file name including a file path where the exported document will be located, and the XML data format.
Note
You may need to add the DevExpress.
using System.Windows.Forms;
using DevExpress.Pdf;
namespace ExportAcroFormDocument {
public partial class Form1 : Form {
public Form1() {
InitializeComponent();
// Load a PDF document with AcroForm data.
pdfViewer1.LoadDocument("..\\..\\AcroForm.pdf");
// Export the document to the xml format.
pdfViewer1.Export("..\\..\\AcroForm.xml", PdfFormDataFormat.Xml);
}
}
}
