I have a python app in Google App Engine, and when I try to fetch an XML feed, nothing happens, except in the log console in the AppEngineLauncher, I get\[code\]WARNING 2013-03-21 23:37:39,482 urlfetch_stub.py:453] Stripped prohibited headers from URLFetch request: ['Host']\[/code\]Here is my code:\[code\]class FindStops(webapp2.RequestHandler): def post(self): bound=self.request.POST["bound"] line=self.request.POST["stop"] stops=urllib2.urlopen("http://webservices.nextbus.com/service/publicXMLFeed?command=routeConfig&a=sf-muni&r=" + line) tree=ET.parse(stops) root=tree.getroot() title=list() for info in tree.findall('stop'): title.append(info.get('title')) for name in title: self.response.out.write(name)\[/code\]And here is what the XML looks like:\[code\]<body copyright="All data copyright San Francisco Muni 2013."><route tag="F" title="F-Market & Wharves" color="555555" oppositeColor="ffffff" latMin="37.7625199" latMax="37.8085899" lonMin="-122.43487" lonMax="-122.39345"><stop tag="5184" title="Jones St & Beach St" lat="37.8072499" lon="-122.41737" stopId="15184"/><stop tag="3092" title="Beach St & Mason St" lat="37.80741" lon="-122.4141199" stopId="13092"/><stop tag="3095" title="Beach St & Stockton St" lat="37.8078399" lon="-122.41081" stopId="13095"/>...\[/code\]I'm pretty sure I"m parsing the XML correctly, but the self.response.out.write prints out nothing, so I'm at a loss here.
