I'm glad to see the interest in things computer, but perl is not the best choice for xml schema handling, or arguably much else. Here is a python example of reading gpx and making csv files out of them.

Python and XML -- by Mike Hostetler ,

The program is trivial in python (this is the whole thing, I just use php tags cuz it looks pretty, it is python), worked as-is for me:

PHP Code:

import cElementTree as ET
import string

if __name__ == '__main__':

    mainNS=string.Template("{http://www.topografix.com/GPX/1/0}$tag")

    wptTag=mainNS.substitute(tag="wpt")
    nameTag=mainNS.substitute(tag="name")

    et=ET.parse(open("everything.gpx"))

    for wpt in et.findall("//"+wptTag):
        wptinfo=[]
        wptinfo.append(wpt.get("lat"))
        wptinfo.append(wpt.get("lon"))
        wptinfo.append(wpt.findtext(nameTag))

        print ",".join(wptinfo) 


and here was the output ( after I saved http://www.topografix.com/fells_loop.gpx to everything.gpx )
