Inspect method not picking up embedded JavaScript

[mthomasuk]

Hey guys, really enjoying using unidoc, just spotted something (and apologies if this is an oversight)

The pdfReader.Inspect method doesn't appear to pull the JavaScript out of the following file:

%PDF-1.7
4 0 obj
<<
/Length 0
>>
stream

endstream endobj
5 0 obj
<<
/Type /Page
/Parent 2 0 R
/Resources 3 0 R
/Contents 4 0 R
/MediaBox [ 0 0 612 792 ]

>>
 endobj
1 0 obj
<<
/Type /Catalog
/Pages 2 0 R
/OpenAction [ 5 0 R /Fit ]
  /Names << % the Javascript entry
    /JavaScript <<
      /Names [
        (EmbeddedJS)
        <<
          /S /JavaScript
          /JS (
            app.alert('Hello, World!');
          )
        >>
      ]
    >>
  >> % end of the javascript entry
>>
 endobj
2 0 obj
<<
/Type /Pages
/Count 1
/Kids [ 5 0 R ]

>>
 endobj
3 0 obj
<<
>>
 endobj
xref

0000000305 00000 n 
0000000009 00000 n 
0000000058 00000 n 
trailer <<
/Size 6
/Root 1 0 R
>>
startxref

%%EOF

It correctly identifies the number of pages and etc, just doesn't pick up the JS around line 25

Additional question: do you guys support stripping this kind of stuff from the file? The example does a great job of explaining how to find JS/Flash/Video in a PDF, but not how to remove (if possible)

Thanks!

Thanks. The reason is that the Inspect method is currently not recursive, only looks at the objects at the first-level (looping through the indirect objects).

To make this work. We need to refactor the parser.inspect method to walk through the PDF object structure recursively.
