RE: A simple guy with a simple problem

I was curious to see how far I could get towards solving Bob's problem using
SAX, and the more I looked the more problems I encountered. I was stumped
before I even started coding.

Maybe Mr. Megginson might have something to say on Bob's little problem?

I'll take the traditional route and wrap 'it was a stupid problem anyway' in
something arguably valid : Bob's manager's son-in-law is looking for a job,
and so any conclusions from this task won't reflect the relative merits of
different approaches to real-world problems.

I was strongly deterred, but I couldn't resist hacking a Java SAX echo just
to see how straightforward that could be.
http://www.isacat.net/2001/code/echo/echo.htm if anyone wants to try the
tricky bits.

BTW, how well does the XSL version work?


fyi, the echo did this (prolog & doctype hardcoded):

<?xml version="1.0"?>
<!DOCTYPE foo SYSTEM "foo.dtd" [
<!ENTITY bar "This is entity STUFF and some more
<lit text="hello">
<![CDATA[This is literal STUFF and some more STUFF.]]>

<?xml version="1.0"?>
<!DOCTYPE foo SYSTEM "foo.dtd">
<foo><lit text="hello">
This is literal STUFF and some more STUFF.
</lit><lit text="STUFF">
This is entity STUFF and some more
