美丽的汤 - 处理错误

Question

1. I'd like to know how to handle a situation when href doesn't exist after the <strong>Text:</strong>

2. Is there a better way to search for the content that exists after <strong>Contact:</strong>

Answer 1

How about findNext ?

import re
from BeautifulSoup import BeautifulSoup

html = '''<strong>Text:</strong>   

        <a href='http://domain.com'>url</a>'''

soup = BeautifulSoup(html)
label = soup.find("strong" , text='Text:')
contact = label.findNext('a')

if contact.get('href') != None:
    print contact
else:
    print "No href"

If you're looking specifically for an a tag with an href , use:

contact = label.findNext('a', attrs={'href' : True})

With this you won't need to condense whitespace. I imagine you did this because next was returning the whitespace after the label.
