Are most XML parsers recursive in nature?
My parser in non-recursing while processing the tags from an XML file
and only recurses once to go back and load an XSL file, when applicable.

My reasoning for not using recursion was performance (function call/stack framing
considerations) and that it made the code easier to understand.  

It would be interesting to do some benchmarks on various parsers out there to
measure performance.  The Java parsers I've tested (Sun, IBM) are _dog_ slow
compared to expat, etc.  For server-side I don't think that matters, since in
the corporate scene people tend to just add more servers/infrastructure and 
not worry about performance.                                                   

Client-side XML is a completely different kettle o' fish tho' since you can't
just keep popping in processors every time your machine at home/work bogs down.
