Masterview devel - Jan 2008 - Interesting perf tidbit on REXML

http://antoniocangiano.com/2007/02/10/top-10-ruby-on-rails-performance-tips/

Suggests checking out libxml, a ruby binding on the gnome xml parser, 
for perf improvement.  From one of the comments:

- The author is dead right about the speed of REXML. REXML (in 
DOM-style mode, at least) is unforgivably slow if you?re parsing large 
files (ditto for massive quantities of small ones). If you can 
guarantee their well-formedness, Libxml is unbelievably fast. If you 
can?t, consider Hpricot?s XML mode. REXML?s stream parser might be 
decent, haven?t really used it.

Might be worth exploring at some point to see if we can make the xml 
parser be configurable/pluggable to allow apps to optimize

Yeah, it would be nice to be pluggable. Will have to research what this
would take to do.
