Leonard,
Thanks for the quick response. I need to suppress this information because we handle peer-reviewed documents. The evaluators must remain anonymous and sometimes there is need to send their evaluations back to a submitting author. On occasion the evaluator's name will appear in XMP data that has been included unwittingly so we need to remove this data before it gets forwarded.
I am resetting the metadata in the DocInfo fields as shown in the iText examples so this isn't a problem - but I thank you for bringing it up!
I have to tell you that I am fairly new to processing pdf docs as well as the proper use of iText so I am not quite sure of how to walk the object tree and search for XMP streams in a comprehensive way. Is there an example of this someplace?
Thanks, Greg

Why?
Are you also clearing the "DocInfo" fields as well?
This seems to work just fine but I see in the PDF spec that XMP metadata can be contained in any components that are represented as a stream or dictionary.
Correct. However, AFAIK, the only common location for it is on image dictionaries.
Does anyone know if there as a way to find and remove all those metadata streams if they exist anywhere in the document? Thanks, Greg
You can do it with our PDF Enhancer product (http://www.pdfenhancer.com).
It is possible using iText - but it requires walking the object tree and looking for the XMP key...
But again - why would you want to do this?!?!
