In the Winhec presentation on XPS document performance optimization, a simple program XpsStat is introduced to analyze XPS documents. 

Given an XPS document, XpsStat generates four or five tables in HTML format:

  • Container Summary Table: information about each type of parts in the document.
  • FixedPage / Remote Resource Dictionary Table: information about each fixed page / remote resource dictionary in the document.
  • Font Resource Table: information about each font resource in the document
  • Image Resource Table: information about each image resource in the document
  • Container Part Table (optional): information about each part in the document

The program has three command line options:

  • /x Generate report in XML format instead of the default HTML format
  • /a Generate the optional Container Part Table
  • /d Extract fonts to external files, unobfuscated.

The program is written using .Net 3.0 XPS related API and some direct parsing of ZIP container. It supports both interleaved and non-interleaved XPS files.

Here is what the Container Summary Table the program will generate for XPS Specification 1.0 in XPS format:
