BeautifulSoup - search by text inside a tag

in one line using lambda

soup.find(lambda tag:tag.name=="a" and "Edit" in tag.text)

You can pass a function that return True if a text contains "Edit" to .find

In [51]: def Edit_in_text(tag):
   ....:     return tag.name == 'a' and 'Edit' in tag.text
   ....: 

In [52]: soup.find(Edit_in_text, href="/customer-menu/1/accounts/1/update")
Out[52]: 
<a href="/customer-menu/1/accounts/1/update">
<i class="fa fa-edit"></i> Edit
</a>

---

EDIT:

You can use the .get_text() method instead of the text in your function which gives the same result:

def Edit_in_text(tag):
    return tag.name == 'a' and 'Edit' in tag.get_text()

The problem is that your <a> tag with the <i> tag inside, doesn't have the string attribute you expect it to have. First let's take a look at what text="" argument for find() does.

NOTE: The text argument is an old name, since BeautifulSoup 4.4.0 it's called string.

From the docs:

Although string is for finding strings, you can combine it with arguments that find tags: Beautiful Soup will find all tags whose .string matches your value for string. This code finds the tags whose .string is “Elsie”:

soup.find_all("a", string="Elsie")
# [<a href="http://example.com/elsie" class="sister" id="link1">Elsie</a>]

Now let's take a look what Tag's string attribute is (from the docs again):

If a tag has only one child, and that child is a NavigableString, the child is made available as .string:

title_tag.string
# u'The Dormouse's story'

(...)

If a tag contains more than one thing, then it’s not clear what .string should refer to, so .string is defined to be None:

print(soup.html.string)
# None

This is exactly your case. Your <a> tag contains a text and <i> tag. Therefore, the find gets None when trying to search for a string and thus it can't match.

How to solve this?

Maybe there is a better solution but I would probably go with something like this:

import re
from bs4 import BeautifulSoup as BS

soup = BS("""
<a href="/customer-menu/1/accounts/1/update">
    <i class="fa fa-edit"></i> Edit
</a>
""")

links = soup.find_all('a', href="/customer-menu/1/accounts/1/update")

for link in links:
    if link.find(text=re.compile("Edit")):
        thelink = link
        break

print(thelink)

I think there are not too many links pointing to /customer-menu/1/accounts/1/update so it should be fast enough.
