joby1 · 11-18-2007, 09:53 PM

just found out my server doesn't have php5 and doesn't plan to for months.

am trying to make a geocoding parsing script (i am very newbie to all this)

there is a great php geocde script here - http://www.developer.com/db/article.php/3621981
but uses simplexml command (line 19) that is not used by php4

found this as a possible alternative for simplexml command-
