Findnext Not found.

[akshay1991]

Hello experts,

i found the program on youtube and try to figure out the bus towards to north longitude and latitude near to dave using xml file but it showing me an error....
lat = float(bus.findnext('lat'))

AttributeError: 'xml.etree.ElementTree.Element' object as no attribute 'findnext'


Here's the code,

import urllib
 
daves_latitude = 41.98062
daves_longitude = -87.668452
 
from xml.etree.ElementTree import parse
doc = parse('rt22.xml')
 
for bus in doc.findall('bus'):
    lat = float(bus.findnext('lat'))
    if lat > daves_latitude:
        direction = bus.findnext('d')
        if direction.startwith('North'):
            busid = bus.findnext('id')
            print (busid,lat)
 

here is the xml file link.

Thank you in advance..

As the traceback indicates, bus has no "findnext" method. It has a "findall" method which returns a list.

from xml.etree.ElementTree import parse
 
daves_latitude = 41.98062
daves_longitude = -87.668452
 
doc = parse("rt22.xml")
 
for bus in doc.findall('bus'):
    lat = float(bus.findall('lat')[0].text)
    if lat > daves_latitude:
        direction = bus.findall('d')[0].text
        if direction.startswith('North'):
            busid = bus.findall('id')[0]
            print (busid,lat)
