Maruan Sahyoun commented on TIKA-1857:
--------------------------------------
The reason you are not getting the data is that this is stored as part of the
data node in an xml data structure which matches the binding information in the
field. That data is in {{xfa.datasets.data}} with the {{my_exibitor}} value
stored in the {{Exhibitorname}} field.
Extracting {{speak|text|exData}} will give you the boilerplate text but not the
field value.
Now there are two types of XFA forms - static and dynamic. Static XFA forms
will have an XFA entry and AcroForm fields. Dynamic XFA forms will only have an
XFA entry and no AcroForm fields.
When an XFA form is filled out with an XFA aware PDF processor for static forms
both the {{xfa.datasets.data}} information is updated as well as the {{V}}
entry of the AcroForm form field. If you fill out a static form with a non XFA
aware PDF processor it will only see the AcroForm information and as a result
only updates the AcroForm form fields {{V}} entry.
When trying to fill a dynamic XFA form with a non XFA aware PDF processor it
will not see any form fields at all.
I'm happy to provide more information on that topic but thought that this will
give you a first outline.
