[jdom-interest] Extracting ProcessingInstructions

[Laurent Bihanic]

Hi,

As per the XML specification, the XML header <?xml ... ?> is not a "regular" 
PI. Parsers do not provide any way to access the header information and thus 
JDOM can't get it for you.

If you want to access this information, you should use your own InputStream to 
gather it while the parser is reading the XML stream.
