I am a total newbie to Python, but a veteran programmer.  I am trying to write my first script.  It will take a given URL, parse out all the anchors and display them in a list box.  The user can then select a URL and press a to parse that one into the list box.  Long term goal is to allow users to view videos or pictures from any web site.  Right now it will parse the URL that the user enters, but when they choose a URL from the list, it doesn't parse that, just shows a blank list.  I'm sure my problem has to do with the way I am creating and destroying the CGExtractor class.  Any help is appreciated.  Here is the code:

import urllib
import xbmc, xbmcgui
import imageviewer
from HTMLParser import HTMLParser
 
try: Emulating = xbmcgui.Emulating
except: Emulating = True

BaseURL = "base"
Root = "Q:\\scripts\\CG\\CG\\"
CGHrefList = []

class CGExtractor(HTMLParser):

    def handle_starttag(self, tag, attrs):
        if tag=="a":
            for att, val in attrs:
                if val!=None:
                    if att=="href":
                        CGHrefList.append(parseURL(val))

class CG_Main(xbmcgui.Window):

    def __init__(self):
        if Emulating: xbmcgui.Window.__init__(self)
        w = self.getWidth()
        h = self.getHeight()
        self.hrefList = xbmcgui.ControlList(w*.1,h*.1,w*.9,h*.9)
        self.exit = xbmcgui.ControlButton(1200,1000,200,40, "Exit")
        self.lblStatus = xbmcgui.ControlFadeLabel(100,1200,1000,100, "font12", "0xFFFFFFFF")
        self.addControl(self.lblStatus)
        self.addControl(self.hrefList)
        self.addControl(self.exit)
        keyboard = xbmc.Keyboard("http://")
        keyboard.doModal()
        self.setFocus(self.hrefList)
        self.ProcessURL(keyboard.getText())
        for item in CGHrefList:
            self.hrefList.addItem(item)

    def onControl(self, control):
        print "Event Caught"
        if control == self.hrefList:
            item = self.hrefList.getSelectedItem().getLabel()
            print "Using URL " + item
            self.hrefList.reset()
            print "reset list"
            CGHrefList = []
            print "Processing URL"
            self.ProcessURL(item)
            print "adding items to list"
            for item2 in CGHrefList:
                print "adding " + item2
                self.hrefList.addItem(item2)
        if control == self.exit:
            self.close()
           

    def onAction(self, Action):
        if Action == 10:
            self.close()

    def ProcessURL(self, U):
        print "processURL processing " + U
        CG_Sock = urllib.urlopen(U)
        CG_HTML = CG_Sock.read()
        CG_Sock.close
        p = CGExtractor()
        p.feed(CG_HTML)
        p.close
        del p

def addPic(URL):
    Display_Main.picList.addItem(URL)

def parseURL(URL):
    if URL!=None:
        if URL.startswith("http"):
            pass
        else:
            if URL.startswith("/"):
                URL = BaseURL + URL
            else:
                URL = BaseURL + "/" + URL
    else:
        URL=""
    return URL

global Display_Main
Display_Main = CG_Main()
Display_Main.doModal()
del Display_Main


OK, so HTML eliminated my indenting.  I hope you can still make sense of it.
