Reformatting scraped selenium table

I'm scraping a table that displays info for a sporting league. So far so good for a selenium beginner:

from selenium import webdriver
import re
import pandas as pd

driver = webdriver.PhantomJS(executable_path=r'C:/.../bin/phantomjs.exe')

driver.get("http://www.oddsportal.com/hockey/usa/nhl-2014-2015/results/#/page/2.html")

infotable = driver.find_elements_by_class_name("table-main")
matches = driver.find_elements_by_class_name("table-participant")
ilist, match = [], []

for i in infotable:
    ilist.append(i.text)
    infolist = ilist[0]

for i in matches:
    match.append(i.text)

driver.close()

home = pd.Series([item.split(' - ')[0] for item in match])
away = pd.Series([item.strip().split(' - ')[1] for item in match])

df = pd.DataFrame({'home' : home, 'away' : away})

date = re.findall("\d\d\s\w\w\w\s\d\d\d\d", infolist)

In the last line, date scrapes all the dates in the table but I can't link them to the corresponding game.

My thinking is: for child/element "under the date", date = last_found_date.

Ultimate goal is to have two more columns in df, one with the date of the match and the next if any text found beside the date, for example 'Play Offs' (I can figure that out myself if I can get the date issue sorted).

Should I be incorporating another program/method to retain order of tags/elements of the table?

You would need to change the way you extract the match information. Instead of separately extracting home and away teams, do it in one loop also extracting the dates and events:

from selenium import webdriver

import pandas as pd

driver = webdriver.PhantomJS()
driver.get("http://www.oddsportal.com/hockey/usa/nhl-2014-2015/results/#/page/2.html")

data = []
for match in driver.find_elements_by_css_selector("div#tournamentTable tr.deactivate"):
    home, away = match.find_element_by_class_name("table-participant").text.split(" - ")
    date = match.find_element_by_xpath(".//preceding::th[contains(@class, 'first2')][1]").text

    if " - " in date:
        date, event = date.split(" - ")
    else:
        event = "Not specified"

    data.append({
        "home": home.strip(),
        "away": away.strip(),
        "date": date.strip(),
        "event": event.strip()
    })

driver.close()

df = pd.DataFrame(data)
print(df)

Prints:
