Trying to dig into html to get color.
color = soup.find_all('a', {'class' : 'logsss_event_cl itemAttr current'})
print(color)
What I get is:
[<a class="logsss_event_cl itemAttr current" data-logsss-const-value="{'x': 'change_color'}" data-value="WHITE" href="javascript:void(0)" title="**WHITE**"><img src="https://gloimg.rglcdn.com/rosegal/pdm-product-pic/Clothing/2019/04/24thumb-img/1556072536277922126.jpg"/></a>, <a class="logsss_event_cl itemAttr current" data-logsss-const-value="{'x': 'change_size'}" data-value="3X" href="javascript:void(0)" title="3X">3X</a>] href
What I want is "white"
Your search is returning all values for links with the class logsss_event_cl itemAttr current. If you want the text value, you can accomplish that using the following code:
# first, get all values for colo
color_all = soup.find_all('a', {'class' : 'logsss_event_cl itemAttr current'})
# Next, only get text
color_text = [x.get('title') for x in color_all]

I have a soup object like:
<a class="love-action js-add-to-favorites" data-id="415953" data-price="715.00" href="#">
</a>
I did
soup = BeautifulSoup(src, 'lxml') #передаем переменную в суп
price = soup.find(class_='col-5 col-sm-4 col-lg-7 mob-position detail-top-actions').find('a', class_='love-action js-add-to-favorites')
print(price)
I'd like to get only: 715.00
How to fix?
You can access attributes of a tag by treating it like a dictionary - So simply get the value from the attribute data-price by:
price['data-price']
Example based on your question
soup = BeautifulSoup(src, 'lxml') #передаем переменную в суп
price = soup.find(class_='col-5 col-sm-4 col-lg-7 mob-position detail-top-actions').find('a', class_='love-action js-add-to-favorites')
print(price['data-price'])
Output
715.00
Observe the following problem:
import re
from bs4 import BeautifulSoup as BS
soup = BS("""
<a href="/customer-menu/1/accounts/1/update">
Edit
</a>
""")
# This returns the <a> element
soup.find(
'a',
href="/customer-menu/1/accounts/1/update",
text=re.compile(".*Edit.*")
)
soup = BS("""
<a href="/customer-menu/1/accounts/1/update">
<i class="fa fa-edit"></i> Edit
</a>
""")
# This returns None
soup.find(
'a',
href="/customer-menu/1/accounts/1/update",
text=re.compile(".*Edit.*")
)
For some reason, BeautifulSoup will not match the text, when the <i> tag is there as well. Finding the tag and showing its text produces
>>> a2 = soup.find(
'a',
href="/customer-menu/1/accounts/1/update"
)
>>> print(repr(a2.text))
'\n Edit\n'
Right. According to the Docs, soup uses the match function of the regular expression, not the search function. So I need to provide the DOTALL flag:
pattern = re.compile('.*Edit.*')
pattern.match('\n Edit\n') # Returns None
pattern = re.compile('.*Edit.*', flags=re.DOTALL)
pattern.match('\n Edit\n') # Returns MatchObject
Alright. Looks good. Let's try it with soup
soup = BS("""
<a href="/customer-menu/1/accounts/1/update">
<i class="fa fa-edit"></i> Edit
</a>
""")
soup.find(
'a',
href="/customer-menu/1/accounts/1/update",
text=re.compile(".*Edit.*", flags=re.DOTALL)
) # Still return None... Why?!
Edit
My solution based on geckons answer: I implemented these helpers:
import re
MATCH_ALL = r'.*'
def like(string):
"""
Return a compiled regular expression that matches the given
string with any prefix and postfix, e.g. if string = "hello",
the returned regex matches r".*hello.*"
"""
string_ = string
if not isinstance(string_, str):
string_ = str(string_)
regex = MATCH_ALL + re.escape(string_) + MATCH_ALL
return re.compile(regex, flags=re.DOTALL)
def find_by_text(soup, text, tag, **kwargs):
"""
Find the tag in soup that matches all provided kwargs, and contains the
text.
If no match is found, return None.
If more than one match is found, raise ValueError.
"""
elements = soup.find_all(tag, **kwargs)
matches = []
for element in elements:
if element.find(text=like(text)):
matches.append(element)
if len(matches) > 1:
raise ValueError("Too many matches:\n" + "\n".join(matches))
elif len(matches) == 0:
return None
else:
return matches[0]
Now, when I want to find the element above, I just run find_by_text(soup, 'Edit', 'a', href='/customer-menu/1/accounts/1/update')
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")
# [Elsie]
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.
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()
With soupsieve 2.1.0 you can use :-soup-contains css pseudo class selector to target a node's text. This replaces the deprecated form of :contains().
from bs4 import BeautifulSoup as BS
soup = BS("""
<a href="/customer-menu/1/accounts/1/update">
Edit
</a>
""")
single = soup.select_one('a:-soup-contains("Edit")').text.strip()
multiple = [i.text.strip() for i in soup.select('a:-soup-contains("Edit")')]
print(single, '\n', multiple)
Method - 1: Checking text property
pattern = 'Edit'
a2 = soup.find_all('a', string = pattern)[0]
Method - 2: Using lambda iterate through all elements
a2 = soup.find(lambda tag:tag.name=="a" and "Edit" in tag.text)
Good Luck
so im scraping data from a website and it has some data in its div tag
like this :
<div class="search-result__title">\nDonald Duck <span>\xa0|\xa0</span>\n<span class="city state" data-city="city, TX;city, TX;city, TX;city, TX" data-state="TX">STATENAME, CITYNAME\n</span>\n</div>,
I want to scrape "Donald Duck" part and state and city name after rel="nofollow"
the site contains a lot of data so name and state are different
the code that i have written is
div = soup.find_all('div', {'class':'search-result__title'})
print (div.string)
this gives me a error
"ResultSet object has no attribute '%s'. You're probably treating a list of items like a single item. Did you call find_all() when you meant to call find()?" % key
first, use .text. Second, find_all() will return a list of elements. You need to specify the index value with either: print (div[0].text), or since you will probably have more than 1 element, just iterate through them
from bs4 import BeautifulSoup
html = '''<div class="search-result__title">\nDonald Duck <span>\xa0|\xa0</span>\n<span class="city state" data-city="city, TX;city, TX;city, TX;city, TX" data-state="TX">STATENAME, CITYNAME\n</span>\n</div>'''
soup = BeautifulSoup(html, 'html.parser')
div = soup.find_all('div', {'class':'search-result__title'})
print (div[0].text)
#OR
for each in div:
print (each.text)
i enter dojo.query('input') i get the following :-
<input id="paragraphtwo" data-dojo-type="dijit/form/SimpleTextarea" rows="4" cols="50" style="width:auto">
now WHEN i write
text= dojo.query('input')
[<input id="paragraphtwo" data-dojo-type="dijit/form/SimpleTextarea" rows="4" cols="50" style="width:auto">]
gets storeed in text.
now when i write text[0].id i get "paragraphtwo". how can i access the type of input i.e hwo can i get "dijit/form/SimpleTextarea" just like i got the id
One way to this is as follows:
var input = dojo.byId("paragraphtwo");
var dojoType = dojo.attr(input, "data-dojo-type"));
console.log(dojoType); // Outputs: dijit/form/SimpleTextarea
Using the declaredClass property:
console.log(dijit.byId("paragraphtwo").declaredClass);
I use this method
allcity = dom.body.findAll(attrs={'id' : re.compile("\d{1,2}")})
to return a list like this:
[<a onmousedown="return c({'fm':'as','F':'77B717EA','F1':'9D73F1E4','F2':'4CA6DE6B','F3':'54E5243F','T':'1279189248','title':this.innerHTML,'url':this.href,'p1':1,'y':'B2D76EFF'})" href="http://www.ylyd.com/showurl.asp?id=6182" target="_blank"><font size="3">掳虏驴碌路驴碌脴虏煤脨脜脧垄脥酶 隆煤 脢脦脝路脦露脕卢陆脫</font></a>,
掳脵露脠驴矛脮脮]
How do I extract this href?
http://www.ylyd.com/showurl.asp?id=6182
Thanks. :)
you can use
for a in dom.body.findAll(attrs={'id' : re.compile("\d{1,2}")}, href=True):
a['href']
In this example, there's no real need to use regex, it can be simply as calling <a> tag and then ['href'] attribute like so:
get_me_url = soup.a['href'] # http://www.ylyd.com/showurl.asp?id=6182
# cached URL
get_me_cached_url = soup.find('a', class_='m')['href']
You can always use prettify() method to better see the HTML code.
from bs4 import BeautifulSoup
string = '''

Alternatively, you can do the same thing using Baidu Organic Results API from SerpApi. It's a paid API with a free trial of 5,000 searches.
Essentially, the main difference in this example is that you don't have to figure out how to grab certain elements since it's already done for the end-user with a JSON output.
Code to grab href/cached href from first page results:
from serpapi import BaiduSearch
params = {
"api_key": "YOUR_API_KEY",
"engine": "baidu",
"q": "ylyd"
}
search = BaiduSearch(params)
results = search.get_dict()
for result in results['organic_results']:
# try/expect used since sometimes there's no link/cached link
try:
link = result['link']
except:
link = None
try:
cached_link = result['cached_page_link']
except:
cached_link = None
print(f'{link}\n{cached_link}\n')
# Part of the output:
'''
