[jira] [Updated] (PDFBOX-1297) ExtractText fails to extract text from packaged PDFs

     [ https://issues.apache.org/jira/browse/PDFBOX-1297?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Michael McCandless updated PDFBOX-1297:
---------------------------------------

    Attachment: testPDFPackage.pdf
                PDFBOX-1297.patch

Patch, adding embedded PDF handling to ExtractText, plus a test case
(and test document).

I would really appreciate someone who's more familiar with PDFBox's
APIs having a look at what I did... I had to dig into various classes
that I don't really understand: PDDocumentCatalog,
PDDocumentNameDictionary, PDEmbeddedFilesNameTreeNode,
PDComplexFileSpecification, PDEmbeddedFile.

I only extract text for embedded PDFs but not other content-types.

I noticed Tika's parser also fails to visit embedded documents within
a PDF... I'll open a separate issue.
