How to extract PDF attachments

Question

I receive PDF files (electronic invoices), and there are xml files embedded inside the PDF files I would like to extract and process in a Logic App. I could not find a way to extract the files embedded in PDFs. Any idea? Thanks.

Hello @KaziNad , Sorry for the delay in my response. Currently none of the pdf connectors for logic app support the functionality to extract attached files from the pdf document. An alternate method to extract the attached ‘xml’ file will be to integrate a Function app within your Logic App. You can find more information here about how to call a function app using your logic app. We found this thread which we think might be helpful in implementing the code required to extract the ‘xml’ attachment in pdf using C# language.
Please let me know if you need any additional information, I will be glad to continue with our discussions.

1.Install Nuget Package of IronPdf into your project
2.Follow the link: reading-pdf-text

PdfDocument PDF = PdfDocument.FromFile(@"D:\demoSp.pdf"); // D:\demoSp.pdf full path of your input pdf file
FileContent.Text = PDF.ExtractAllText();

You could try Spire.PDF library to extract attachments from PDF using C#.

//Load PDF
PdfDocument pdf = new PdfDocument("Attachment1.pdf");
//Get the first attachment
PdfAttachment attachment = pdf.Attachments[0];
//Write to file
File.WriteAllBytes(attachment.FileName, attachment.Data);
