Beautifulsoup - nextSibling

问题:

I'm trying to get the content "My home address" using the following but got the AttributeError:

address = soup.find(text="Address:")
print address.nextSibling

This is my HTML:

<td><b>Address:</b></td>
<td>My home address</td>

What is a good way to navigate down td tag and pull the content?

回答1:

The problem is that you have found a NavigableString, not the <td>. Also nextSibling will find the next NavigableString or Tag so even if you had the <td> it wouldn't work the way you expect.

This is what you want:

address = soup.find(text="Address:")
b_tag = address.parent
td_tag = b_tag.parent
next_td_tag = td_tag.findNext('td')
print next_td_tag.contents[0]

Or more concise:

print soup.find(text="Address:").parent.parent.findNext('td').contents[0]

Actually you could just do

print soup.find(text="Address:").findNext('td').contents[0]

Since findNext just calls next over and over again, and next finds the next element as parsed repeatedly until it matches.

Try this if you use bs4:

print soup.find(string="Address:").find_next('td').contents[0]

You can use findChildren pretty easily to iterate over the td's in a table, assuming it's in a table. You could find the table first, ideally:

table = soup.find('table')
>>> for td in table.findChildren('td'):
...:     print td.text
...:     
...:     
Address:
My home address

Or you could search for address, and get the table container:

>>> import re
>>> search = re.compile('Address')
>>> table = soup.find(text=search).parent.parent.parent
