Disassemble portfolio, how to?

hi,

i have problem with disassembling PDF portfolio.

I have process in cycle, which is assemble few forms with XFA data into a pdf's. At the end of this process, after loop, it makes a portfolio like this :
  <PDF result="Acrobat 9 Portfolio">
    <Portfolio>
      <Navigator source="AdobeRevolve.nav"/>
      <Schema>
        <Field name="Character" type="Filename"/>
        <Field name="Location" type="Text"/>
      </Schema>
    </Portfolio>
    <PackageFiles>
      <PDF source="Swami.pdf"/>
      <PDF source="Sherlock.pdf"/>
      <FieldData name="Location">London</FieldData>
    </PackageFiles>
  </PDF>

This portfolio i will send to user and he should fill it up and send it back to me. For disassemble portfolio i tried
  <PDFsFromBookmarks prefix="Animal">
    <PDF source="doc1"/>
  </PDFsFromBookmarks>

but in Assembler result i got no documents like in attachement can see.

I need help with this? Thanks a lot.
