beautifulSoup html csv

Question

Good evening, I have used BeautifulSoup to extract some data from a website as follows:

from BeautifulSoup import BeautifulSoup
from urllib2 import urlopen

soup = BeautifulSoup(urlopen('http://www.fsa.gov.uk/about/media/facts/fines/2002'))

table = soup.findAll('table', attrs={ "class" : "table-horizontal-line"})

print table

This gives the following output:

[<table width="70%" class="table-horizontal-line">
<tr>
<th>Amount</th>
<th>Company or person fined</th>
<th>Date</th>
<th>What was the fine for?</th>
<th>Compensation</th>
</tr>
<tr>
<td><a name="_Hlk74714257" id="_Hlk74714257">&#160;</a>£4,000,000</td>

I would like to export this into CSV whilst keeping the table structure as displayed on the website, is this possible and if so how?

Thanks in advance for the help.

Answer 1

Here is a basic thing you can try. This makes the assumption that the headers are all in the <th> tags, and that all subsequent data is in the <td> tags. This works in the single case you provided, but I'm sure adjustments will be necessary if other cases :) The general idea is that once you find your table (here using find to pull the first one), we get the headers by iterating through all th elements, storing them in a list. Then, we create a rows list that will contain lists representing the contents of each row. This is populated by finding all td elements under tr tags and taking the text, encoding it in UTF-8 (from Unicode). You then open a CSV, writing the headers first and then writing all of the rows, but using(row for row in rows if row)` to eliminate any blank rows):

In [117]: import csv

In [118]: from bs4 import BeautifulSoup

In [119]: from urllib2 import urlopen

In [120]: soup = BeautifulSoup(urlopen('http://www.fsa.gov.uk/about/media/facts/fines/2002'))

In [121]: table = soup.find('table', attrs={ "class" : "table-horizontal-line"})

In [122]: headers = [header.text for header in table.find_all('th')]

In [123]: rows = []

In [124]: for row in table.find_all('tr'):
   .....:     rows.append([val.text.encode('utf8') for val in row.find_all('td')])
   .....: 

In [125]: with open('output_file.csv', 'wb') as f:
   .....:     writer = csv.writer(f)
   .....:     writer.writerow(headers)
   .....:     writer.writerows(row for row in rows if row)
   .....: 

In [126]: cat output_file.csv
