Question :

python BeautifulSoup parsing table

I’m learning python requests and BeautifulSoup. For an exercise, I’ve chosen to write a quick NYC parking ticket parser. I am able to get an html response which is quite ugly. I need to grab the lineItemsTable and parse all the tickets.

You can reproduce the page by going here: https://paydirect.link2gov.com/NYCParking-Plate/ItemSearch and entering a NY plate T630134C

soup = BeautifulSoup(plateRequest.text)
#print(soup.prettify())
#print soup.find_all('tr')

table = soup.find("table", { "class" : "lineItemsTable" })
for row in table.findAll("tr"):
    cells = row.findAll("td")
    print cells

Can someone please help me out? Simple looking for all tr does not get me anywhere.

Answer #1:

Here you go:

data = []
table = soup.find('table', attrs={'class':'lineItemsTable'})
table_body = table.find('tbody')

rows = table_body.find_all('tr')
for row in rows:
    cols = row.find_all('td')
    cols = [ele.text.strip() for ele in cols]
    data.append([ele for ele in cols if ele]) # Get rid of empty values

This gives you:

[ [u'1359711259', u'SRF', u'08/05/2013', u'5310 4 AVE', u'K', u'19', u'125.00', u'$'], 
  [u'7086775850', u'PAS', u'12/14/2013', u'3908 6th Ave', u'K', u'40', u'125.00', u'$'], 
  [u'7355010165', u'OMT', u'12/14/2013', u'3908 6th Ave', u'K', u'40', u'145.00', u'$'], 
  [u'4002488755', u'OMT', u'02/12/2014', u'NB 1ST AVE @ E 23RD ST', u'5', u'115.00', u'$'], 
  [u'7913806837', u'OMT', u'03/03/2014', u'5015 4th Ave', u'K', u'46', u'115.00', u'$'], 
  [u'5080015366', u'OMT', u'03/10/2014', u'EB 65TH ST @ 16TH AV E', u'7', u'50.00', u'$'], 
  [u'7208770670', u'OMT', u'04/08/2014', u'333 15th St', u'K', u'70', u'65.00', u'$'], 
  [u'$0.00nnnPayment Amount:']
]

Couple of things to note:

  • The last row in the output above, the Payment Amount is not a part
    of the table but that is how the table is laid out. You can filter it
    out by checking if the length of the list is less than 7.
  • The last column of every row will have to be handled separately since it is an input text box.

Answer #2:

Solved, this is how your parse their html results:

table = soup.find("table", { "class" : "lineItemsTable" })
for row in table.findAll("tr"):
    cells = row.findAll("td")
    if len(cells) == 9:
        summons = cells[1].find(text=True)
        plateType = cells[2].find(text=True)
        vDate = cells[3].find(text=True)
        location = cells[4].find(text=True)
        borough = cells[5].find(text=True)
        vCode = cells[6].find(text=True)
        amount = cells[7].find(text=True)
        print amount

If a programmer is interested only parsing table from webpage, they can utilize the pandas method pandas.read_html.

Let’s say we want to extract the GDP data table from the website: https://worldpopulationreview.com/countries/countries-by-gdp/#worldCountries

Then following codes does the job perfectly (No need of beautifulsoup and fancy html):

import pandas as pd
import requests

url = "https://worldpopulationreview.com/countries/countries-by-gdp/#worldCountries"

r = requests.get(url)
df_list = pd.read_html(r.text) # this parses all the tables in webpages to a list
df = df_list[0]
df.head()

Output

First five lines of the table from the Website

Answer #4:

Here is working example for a generic <table>. (question links-broken)

Extracting the table from here countries by GDP (Gross Domestic Product).

htmltable = soup.find('table', { 'class' : 'table table-striped' })
# where the dictionary specify unique attributes for the 'table' tag

The tableDataText function parses a html segment started with tag <table> followed by multiple <tr> (table rows) and inner <td> (table data) tags. It returns a list of rows with inner columns. Accepts only one <th> (table header/data) in the first row.

def tableDataText(table):       
    rows = []
    trs = table.find_all('tr')
    headerow = [td.get_text(strip=True) for td in trs[0].find_all('th')] # header row
    if headerow: # if there is a header row include first
        rows.append(headerow)
        trs = trs[1:]
    for tr in trs: # for every table row
        rows.append([td.get_text(strip=True) for td in tr.find_all('td')]) # data row
    return rows

Using it we get (first two rows).

list_table = tableDataText(htmltable)
list_table[:2]

[['Rank',
  'Name',
  "GDP (IMF '19)",
  "GDP (UN '16)",
  'GDP Per Capita',
  '2019 Population'],
 ['1',
  'United States',
  '21.41 trillion',
  '18.62 trillion',
  '$65,064',
  '329,064,917']]

That can be easily transformed in a pandas.DataFrame for more advanced tools.

import pandas as pd
dftable = pd.DataFrame(list_table[1:], columns=list_table[0])
dftable.head(4)

pandas DataFrame html table output
