need help with php/xml/template !!!

hi... i'm playing around with trying to get a better understanding of an app (www.sitellite.org) it uses templates, which appear to have php/xml/html and i'm trying to understand it a little better. is there someone i can talk to who has a few minutes that might be willing to walk me through this. i'm in the bay area of cali, if you're close i'd even do lunch!! if you're not, talking via phone would probably be enough to get me started! thanks -bruce bedouglas@earthlink.net ps: sample code ----- <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "DTD/xhtml1-transitional.dtd"> <xt:tpl version="1.0"><xt:doctype root="html" access="public" name="-//W3C//DTD XHTML 1.0 Transitional//EN" uri="http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd" /> <html> <head> <title xt:content="php: intl_get ('SCM Example Site') .
