FW: xmp parsing issue -- xmp should start with a processing
instruction
All,
This is a separate issue than I raised in PDFBox-2855. This, too, was initially noted by Jeremy Anderson on TIKA-1285. I'm not sure if this is a problem with the way our xmp was generated or with the xmp parser. I'm fairly confident the former, but wanted to check.
In our test suite, we have a file that is intended to test multi-lingual titles in xmp. I _think_ we generated this file with an older version of PDFBox+jempbox (vintage 1.6???), but I can't remember any more.
The XMP is:
<x:xmpmeta xmlns:x="adobe:ns:meta/">
<rdf:RDF xmlns:foaf="http://xmlns.com/foaf/0.1/" xmlns:rdf="http://www.w3.org/1999/02/22-rdf-syntax-ns#">
<rdf:Description xmlns:dc="http://purl.org/dc/elements/1.1/" rdf:about="">
<dc:creator rdf:resource="mailto:plindenbaum@yahoo.fr"/>
<dc:title>
<rdf:Alt>
<rdf:li xml:lang="x-default">Hello World</rdf:li>
<rdf:li xml:lang="fr-ca">Bonjour World</rdf:li>
<rdf:li xml:lang="zh-cn">????</rdf:li>
</rdf:Alt>
</dc:title>
<dc:date>2010-07-11</dc:date>
</rdf:Description>
</rdf:RDF>
</x:xmpmeta>
The stacktrace is:
org.apache.xmpbox.xml.XmpParsingException: xmp should start with a processing instruction
at org.apache.xmpbox.xml.DomXmpParser.parse(DomXmpParser.java:135)
at org.apache.tika.parser.pdf.PDFParser.extractMetadata(PDFParser.java:207)
at org.apache.tika.parser.pdf.PDFParser.parse(PDFParser.java:127)
The original file PDF file is available here: http://svn.apache.org/repos/asf/tika/trunk/tika-parsers/src/test/resources/test-documents/testPDFTripleLangTitle.pdf
This file was parsed without a problem by jempbox, but we get the exception in 2.0.0. Should I open an issue for this or is this user error, and we need to regenerate our test file to yield correct xmp?
Thank you.
Best,
Tim

Thank you, Tilman. Will regenerate new test file.

Hi,
We got more restrictive in 2.0 after doing the Bavaria pdfa tests. That
file is missing "<?xpacket " at the beginning.
