I see -
Isn't there an exisitng plug-in or other facility within the current Acrobat reader to read XML data ?

I just tried saving off saving off an exsting PDF file as xml
using Acrobat 9.0 professional using <file><Save As Xml> and it worked - the output was realistically XML data - with a schema , etc. and recognizable heirarchical relationships, etc.
but it was not readable ....
Isn't there an existing Adobe facility which allows it to read in the xml format that it creates ?

This is quite close to what I am trying to implement.
I'll bet that the developers have this little item at their disposal and the marketing department isnt even aware of the market potential -
If not , then I would like to suggest a new, inexpensive (add-on , plug-in, etc) enhancement to the Acrobat reader -
A utility that will read in the XML data format that Acrobat Professional generates ...

I am being quite serious - there is a great need for this and it would serve the needs of your already existing clientelle - quite nicely . (namely --- me)
I hope that you can either - pass this along to the marketing groups -- (I volunteer to Beta the software)
or pass me along to the required Third Part you have alreeady mentioned ... (I am hoping for Beta status )
Thanks for the help

Cheers
