9.12. Extract XMP Data to XML

The utility program ExtractXMPData writes the document level XMP data from a PDF document into an XML file. This file can be used for the PDFUnit tests described in section 3.38: “XMP Data”.

XMP data can be found on other places in the PDF than just the document level. Such XMP data is currently not extracted. But it is intended to provide the extraction of all XMP data in the next release of PDFUnit.
