Re: multiple input files to one output file

[Steve Tinney <stinney at sas dot upenn dot edu>]

If you can use Saxon for your application, take a good long look at the
docs for both the extension facilities and the API.  For a large set of
data like this it will probably be worth writing a Java program which
caches the stylesheet and applies it to the list of files.

You could either use Java's directory walking routines to generate the
file list, or have two stylesheets in your Java app.  The first could
process the XML files to extract the filenames/URLs; you could capture
the output of that internally, and then use it to drive the iteration of
the second sheet.
