I want to load into my model, the team "city", "name" and "alias" along with the parent "division label", "conference label" and "season".
In Python, I iterate through the data as follows:
from lxml import etree
doc = etree.parse('thisxmlfile.xml')
for s in doc.xpath('//season'):
for c in doc.xpath('//conference'):
for t in doc.xpath('//conference/division/team'):
print s.get('season'), c.get('label'), t.get('city'), t.get('name'), t.get('alias')
But of course, it iterates through all "team" tags twice - once for each "conference" tag. What I want to do is iterate through all "team" tags once and get the parent "division label", parent "conference label" and parent "season season".
Pretty sure I need to reference XPATH Axes and was looking for some help?
The output I'm looking for is:
2012 AFC Buffalo Bills Buf
2012 AFC Miami Dolphins Mia
2012 AFC New England Patriots NE
.
.
.
2012 NFC New Orleans Saints NO
2012 NFC Tampa Bay Buccaneers TB
2012 NFC Carolina Panthers Car
Note: the above output does not include the "division label" but once I figure out how to get the "conference label", it should be easy.
Thanks in advance for any help.
Here is how you can get the wanted output:
from lxml import etree
doc = etree.parse('thisxmlfile.xml')
# There is only one "season" element
season = doc.find('season').get('season')
# XPath query relative to root node
for conference in doc.xpath('conference'):
# XPath query relative to "conference" node
for team in conference.xpath('division/team'):
print season, conference.get('label'),
print team.get('city'), team.get('name'), team.get('alias')
