Just to this: I disagree. IIRC, there's no such thing as '/Title' etc in 
PostScript - these will all be PostScript functions defined by whatever made 
the document.  So a generic tool won't have any way to extract semantics like 
titles from a document.

The OP presumably has the specific output of a particular tool with this nice 
well structured postscript, so he needs to write his/her own special parser.
