python minidom在结果中使用冒号解析XML feed

Question

I am trying to parse an XML feed that displays NFL schedules, one of the attributes is the game time and it looks like this GameTime="8:30 PM"

Here's a clip of what the XML looks like

<Schedule Season="2010" Timezone="Eastern">
  <Game gameId="1" Week="1" GameDate="2010-09-09" AwayTeam="MIN" HomeTeam="NO" GameTime="8:30 PM"/>
  <Game gameId="2" Week="1" GameDate="2010-09-12" AwayTeam="MIA" HomeTeam="BUF" GameTime="1:00 PM"/>
  <Game gameId="3" Week="1" GameDate="2010-09-12" AwayTeam="DET" HomeTeam="CHI" GameTime="1:00 PM"/>
  <Game gameId="4" Week="1" GameDate="2010-09-12" AwayTeam="OAK" HomeTeam="TEN" GameTime="1:00 PM"/>
</Schedule>

Here's my code to read it

url="http://example.com/schedule.xml"
dom = minidom.parse(urllib2.urlopen(url))

for node in dom.getElementsByTagName('Game'):
    print node.getAttribute('AwayTeam'),
    print node.getAttribute('HomeTeam'),
    print node.getAttribute('Week'),
    print node.getAttribute('gameId'),
    print node.getAttribute('GameDate'),
    print node.getAttribute('GameTime')

It prints what I'd expect until I add that last line. ETA: Once this last line is added, it goes from printing lines from the XML to nothing.

 print node.getAttribute('GameTime')

I'd assume it is because there is a colon in the returned data, but I can't find anything to assist me with either escaping that to allow it to print or ignoring it.

Any help would be most appreciated.

I tried to reproduce your error, but it printed just fine for me.

I tried loading your data from a string within the Python module, I tried loading your data from a named file, and I tried loading your data from a file object. They all handled the colon just fine.

The only difference now seems to be the way you get the data: urllib2.openurl(). Perhaps the data returned by that function is not exactly what minidom expects. Or perhaps it does something with the colon character.

Here is the code I used (The test.xml file contains the same xml data as in the triple-quoted string):

from xml.dom import minidom

src = """
<Schedule Season="2010" Timezone="Eastern">
  <Game gameId="1" Week="1" GameDate="2010-09-09" AwayTeam="MIN" HomeTeam="NO" GameTime="8:30 PM"/>
  <Game gameId="2" Week="1" GameDate="2010-09-12" AwayTeam="MIA" HomeTeam="BUF" GameTime="1:00 PM"/>
  <Game gameId="3" Week="1" GameDate="2010-09-12" AwayTeam="DET" HomeTeam="CHI" GameTime="1:00 PM"/>
  <Game gameId="4" Week="1" GameDate="2010-09-12" AwayTeam="OAK" HomeTeam="TEN" GameTime="1:00 PM"/>
</Schedule>
"""

def test_print(dom):
    for node in dom.getElementsByTagName('Game'):
        print node.getAttribute('AwayTeam'),
        print node.getAttribute('HomeTeam'),
        print node.getAttribute('Week'),
        print node.getAttribute('gameId'),
        print node.getAttribute('GameDate'),
        print node.getAttribute('GameTime')
    print ''

dom = minidom.parseString(src)
test_print(dom)

dom = minidom.parse('data.xml')
test_print(dom)

f = open('data.xml', 'r')
dom = minidom.parse(f)
test_print(dom)
f.close()

url = 'http://api.fantasyfootballnerd.com/ffnScheduleXML.php?apiKey=1'
dom = minidom.parse(urllib2.urlopen(url))
test_print(dom)
