Read XMP from existing PDF with iTextSharp

问题

How can I read XMP from an existing PDF file using iTextSharp?

回答1:

I'm dangerously ignorant of itextSharp but this did the job for me:

    PdfReader pdf = new PdfReader(fileName);
    string metadataXml = System.Text.Encoding.Default.GetString(pdf.Metadata);

回答2:

I'd encourage you to check out the iTextSharp.text.xml.xmp namespace.

I've never done what you're trying to do but the XmpReader class looks promising.
