Hello all,
I'm quite new to PDFbox and currently figuring out how to extract metadata from PDF files which is in XMP format. I have a few files containing XMP metadata, but I can not get any of those to work. And I can't seem to figure out where I am failing. A code snippet (all non-relevant code was deleted): String inputFile = "/some/file.pdf" PDDocument pdfDocument = null; pdfDocument = new PDDocument(); pdfDocument = PDDocument.load(inputFile); PDMetadata pdfMetaData = new PDMetadata(pdfDocument); int metadataLength = pdfMetaData.getLength(); System.out.println(pdfMetaData.getLength()); pdfMetaData.exportXMPMetadata(); The getLength call always returns 0; the exportXMPMetadata call returns an error: [Fatal Error] :-1:-1: Premature end of file. Exception in thread "main" java.io.IOException: Premature end of file. at org.apache.jempbox.impl.XMLUtil.parse(XMLUtil.java:78) at org.apache.jempbox.xmp.XMPMetadata.load(XMPMetadata.java:554) at org.apache.pdfbox.pdmodel.common.PDMetadata.exportXMPMetadata(PDMetadata.java:86) at com.robindiederen.pdf.Extractor.extractMetaDataFromXMP(Extractor.java:124) at com.robindiederen.pdf.Extractor.main(Extractor.java:90) This happens for every PDF I test. Extracting metadata from the DocumentInformation table works as a charm. I'm using PDFbox 0.80 on Java 1.5. Any help would be appreciated! Best, Robin
