What I want is to extract the value of person id and in case plan selected ="yes" i further want to extract all activity type and leg mode. It should be stored in the existing order as a dictionary for example (or data frame, it doesn't matter really).
So the ideal outcome would look like this:
id leg_activity
101 outside; car; work; car; outside
102 inside; bike; work; bike; work ...
...
So far I've only worked with JMSPath and I know it is not the most suitable, so I'm happy to see other approaches with elementtree or so:) Also, I was unable to find a way to extract activityand leg information in one step. This is my approach so far:
import gzip
import xmltodict
import pandas as pd
import jmespath
box = xmltodict.parse(gzip.open(gzipfile, 'r'))
expression = jmespath.compile('population.person[].plan[?"@selected"==`yes`].activity[*].["@type"]')
coords = expression.search(box)
coords = pd.DataFrame.from_dict(coords)
Assuming that your xml is inside test.xml, the following should work:
from bs4 import BeautifulSoup
import pandas as pd
soup = BeautifulSoup(open('test.xml'), features='lxml')
plan_log = []
for person in soup.find_all('person'):
log = {'id': person.get('id')}
activities = []
for plan in person.find_all('plan', attrs={'selected': 'yes'}):
for detail in plan.children:
if detail.name == 'activity':
activities.append(detail.get('type'))
elif detail.name == 'leg':
activities.append(detail.get('mode'))
# activities.append(detail.get('type') or detail.get('mode'))
log['leg_activity'] = ', '.join(activities)
plan_log.append(log)
df = pd.DataFrame(plan_log)
print(df)
Output:
id leg_activity
0 101 outside, car, work, car, outside
1 102 inside, bike, work, bike, work, pt, outside
2 103 inside, bike, shopping, bike, work, pt, outside
