I'm trying to scrape the data-ppu value from this line of HTML code called trade_data:

<input class="tradeForm" data-id="10397992" data-ppu="3893" data-toggle="tooltip" maximum="16450" name="rcustomamount" title="Enter Your Desired Amount" type="number" value="16450"/>

I'm using Python 3 and Beautiful Soup. Here's the code I've tried:

for index, trade_data in enumerate(trade_data):
   price = trade_data.find('data-ppu')
   print(price)

However this returns nothing. Any help is greatly appreciated!

CodePudding user response：

What you've asked for is all of the <data-ppu> tags, of which there are none. You need to search the attributes of the tag:

for part in trade_data:
    price = part.findAll( lambda tag: tag.name='input' and 'data-ppu' in tag.attrs)

CodePudding user response：

To get the attributes, you need to do like this:

• Since the data-ppu is an attribute of the <input> tag, you need to first select it and then extract it's attributes.

Selecting the <input> tag

x = soup.find('input')

Extracting the attribute data-ppu

x['data-ppu']

Here is the complete code:

from bs4 import BeautifulSoup
s = """
<input class="tradeForm" data-id="10397992" data-ppu="3893" data-toggle="tooltip" maximum="16450" name="rcustomamount" title="Enter Your Desired Amount" type="number" value="16450"/>
"""

soup = BeautifulSoup(s,'lxml')
x = soup.find('input')
print(x['data-ppu'])

3893
