As another small step in this process of manipulating a data set to upload to Google Maps, I took the cleaned XHTML I had from a few days ago, and used TextWrangler to do some quick search and replaces on the source code in order to produce this XML file.
ranges-data.xml
Next, I think, I’ll load this XML file into PHP using the simplexml features which will make it easy to run the data through a PHP-based GeoCoding processor that I’m sure I can dig up. The goal is to transcode the addresses of the ranges into latitude/longitude points, which seem to be required pieces of data for the KML file I’m trying to piece together.
I may at the same time output the whole thing into KML format, since I’ll be in there with the data nodes anyway.
