I am working on scraping the data from a website using BeautifulSoup. For whatever reason, I cannot seem to find a way to get the text between span elements to print. Here is what I am running.
data = """ <div class="grouping">
<div class="a1 left" style="width:20px;">Text</div>
<div class="a2 left" style="width:30px;"><span
id="target_0">Data1</span>
</div>
<div class="a3 left" style="width:45px;"><span id="div_target_0">Data2
</span></div>
<div class="a4 left" style="width:32px;"><span id="reg_target_0">Data3
</span</div>
</div>
"""
My ultimate goal would be to able to print a list ["Text", "Data1", "Data2"] for each entry. But right now I am having trouble getting python and urllib to produce any text between the . Here is what I am running:
import urllib
from bs4 import BeautifulSoup
url = 'http://target.com'
html = urllib.urlopen(url).read()
soup = BeautifulSoup(html, "lxml")
Search_List = [0,4,5] # list of Target IDs to scrape
for i in Search_List:
h = str(i)
root = 'target_' + h
taggr = soup.find("span", { "id" : root })
print taggr, ", ", taggr.text
When I use urllib it produces this:
<span id="target_0"></span>,
<span id="target_4"></span>,
<span id="target_5"></span>,
However, I also downloaded the html file, and when I parse the downloaded file it produces this output (the one that I want):
<span id="target_0">Data1</span>, Data1
<span id="target_4">Data1</span>, Data1
<span id="target_5">Data1</span>, Data1
Can anyone explain to me why urllib doesn't produce the outcome?
use this code :
...
soup = BeautifulSoup(html, 'html.parser')
your_data = list()
for line in soup.findAll('span', attrs={'id': 'target_0'}):
your_data.append(line.text)
...
similarly add all class attributes which you need to extract data from and write your_data list in csv file. Hope this will help if this doesn't work out. let me know.
You can use the following approach to create your lists based on the source HTML you have shown:
from bs4 import BeautifulSoup
data = """
<div class="grouping">
<div class="a1 left" style="width:20px;">Text0</div>
<div class="a2 left" style="width:30px;"><span id="target_0">Data1</span></div>
<div class="a3 left" style="width:45px;"><span id="div_target_0">Data2</span></div>
<div class="a4 left" style="width:32px;"><span id="reg_target_0">Data3</span></div>
</div>
<div class="grouping">
<div class="a1 left" style="width:20px;">Text2</div>
<div class="a2 left" style="width:30px;"><span id="target_2">Data1</span></div>
<div class="a3 left" style="width:45px;"><span id="div_target_0">Data2</span></div>
<div class="a4 left" style="width:32px;"><span id="reg_target_0">Data3</span></div>
</div>
<div class="grouping">
<div class="a1 left" style="width:20px;">Text4</div>
<div class="a2 left" style="width:30px;"><span id="target_4">Data1</span></div>
<div class="a3 left" style="width:45px;"><span id="div_target_0">Data2</span></div>
<div class="a4 left" style="width:32px;"><span id="reg_target_0">Data3</span></div>
</div>
"""
soup = BeautifulSoup(data, "lxml")
search_ids = [0, 4, 5] # list of Target IDs to scrape
for i in search_ids:
span = soup.find("span", id='target_{}'.format(i))
if span:
grouping = span.parent.parent
print list(grouping.stripped_strings)[:-1] # -1 to remove "Data3"
The example has been slightly modified to show it finding IDs 0 and 4. This would display the following output:
[u'Text0', u'Data1', u'Data2']
[u'Text4', u'Data1', u'Data2']
Note, if the HTML you are getting back from your URL is different to that seen been viewing the source from your browser (i.e. the data you want is missing completely) then you will need to use a solution such as selenium to connect to your browser and extract the HTML. This is because in this case, the HTML is probably being generated locally via Javascript, and urllib does not have a Javascript processor.

<div class="kt-post-card__body>
<div class="kt-post-card__title">Example_1</div>
<div class="kt-post-card__description">Example_2</div>
<div class="kt-post-card__bottom">
<span class="kt-post-card__bottom-description kt-text-truncate" title="Example_3">Example_4</span>
</div>
</div>
'''
according to picture I attached, I want to extract all "kt-post-card__body" attrs and then from each one of them, extract:
("kt-post-card__title", "kt-post-card__description")
like a list.
I tried this:
ads = soup.find_all('div',{'class':'kt-post-card__body'})
but with ads[0].div I only access to "kt-post-card__title" while "kt-post-card__body" has three other sub tags like: "kt-post-card__description" and "kt-post-card__bottom" ... , why is that?
Cause your question is not that clear - To extract the classes:
for e in soup.select('.kt-post-card__body'):
print([c for t in e.find_all() for c in t.get('class')])
Output:
['kt-post-card__title', 'kt-post-card__description', 'kt-post-card__bottom', 'kt-post-card__bottom-description', 'kt-text-truncate']
To get the texts you also have to iterate your ResultSet and could access each elements text to fill your list or use stripped_strings.
Example
from bs4 import BeautifulSoup
html_doc='''
<div class="kt-post-card__body">
<div class="kt-post-card__title">Example_1</div>
<div class="kt-post-card__description">Example_2</div>
<div class="kt-post-card__bottom">
<span class="kt-post-card__bottom-description kt-text-truncate" title="Example_3">Example_4</span>
</div>
</div>
'''
soup = BeautifulSoup(html_doc)
for e in soup.select('.kt-post-card__body'):
data = [
e.select_one('.kt-post-card__title').text,
e.select_one('.kt-post-card__description').text
]
print(data)
Output:
['Example_1', 'Example_2']
or
print(list(e.stripped_strings))
Output:
['Example_1', 'Example_2', 'Example_4']
Try this:
ads = soup.find_all('div',{'class':'kt-post-card__body'})
ads[0]
I think you're getting only the first div because you called ads[0].div
I need to iterate invalid HTML and obtain a text value from all tags to change it.
from bs4 import BeautifulSoup
html_doc = """
<div class="oxy-toggle toggle-7042 toggle-7042-expanded" data-oxy-toggle-active-class="toggle-7042-expanded" data-oxy-toggle-initial-state="closed" id="_toggle-212-142">

Otevřeno: <strong>6 h – do otrhání</strong>, denně</p>
</span></div>
"""
soup = BeautifulSoup(html_doc, "html.parser")
for tag in soup.find_all():
print(tag.name)
if tag.string:
tag.string.replace_with("1")
print(soup)
The result is
<div class="oxy-toggle toggle-7042 toggle-7042-expanded" data-oxy-toggle-active-class="toggle-7042-expanded" data-oxy-toggle-initial-state="closed" id="_toggle-212-142">

<div class="oxy-toggle-content">
<h3 class="ct-headline" id="headline-213-142"><span class="ct-span" id="span-225-142">1</span></h3> </div>
</div><div class="ct-text-block" id="text_block-214-142"><span class="ct-span" id="span-230-142"><p>Začátek sklizně: <strong>1</strong><br/>
Otevřeno: <strong>1</strong>, denně</p>
</span></div>
I know how to replace the text but bs won´t find the text of the paragraph tag. So the texts "Začátek sklizně:" and "Otevřeno:" and ", denně" are not found so I cannot replace them.
I tried using different parsers such as lxml and html5lib won´t make a difference.
I tried python´s HTML library but that doesn´t support changing HTML only iterating it.
.string returns on a tag type object a NavigableString type object -> Your tag has a single string child then returned value is that string, if
it has no children or more than one child it will return None.
Scenario is not quiet clear to me, but here is one last approach based on your comment:
I need generic code to iterate any html and find all texts so I can work with them.
for tag in soup.find_all(text=True):
tag.replace_with('1')
Example
from bs4 import BeautifulSoup
html_doc = """<div class="oxy-toggle toggle-7042 toggle-7042-expanded" data-oxy-toggle-active-class="toggle-7042-expanded" data-oxy-toggle-initial-state="closed" id="_toggle-212-142">

I am new to Python, and never done HTML. So any help would be appreciated.
I need to extract two numbers: '1062' and '348', from a website's inspect element.
This is my code:
page = requests.get("https://www.traderscockpit.com/?pageView=live-nse-advance-decline-ratio-chart")
soup = BeautifulSoup(page.content, 'html.parser')
Adv = soup.select_one ('.col-sm-6 .advDec:nth-child(1)').text[10:]
Dec = soup.select_two ('.col-sm-6 .advDec:nth-child(2)').text[10:]
The website element looks like below:
<div class="nifty-header-shade1 col-xs-12 col-sm-6 col-md-3">
<div class="row">
<div class="col-sm-12">
<h4>Stocks</h4>
</div>
<div class="col-sm-6">
<p class="advDec">Advanced: 1062</p>
</div>
<div class="col-sm-6">
<p class="advDec">Declined: 348</p>
</div>
</div>
</div>
Using my code, am able to extract first number (1062). But unable to extract the second number (348). Can you please help.
Assuming the Pattern is always the same, you can select your elements by text and get its next_sibling:
adv = soup.select_one('a:-soup-contains("Advanced:")').next_sibling.strip()
dec = soup.select_one('a:-soup-contains("Declined:")').next_sibling.strip()
Example
import requests
from bs4 import BeautifulSoup
page = requests.get("https://www.traderscockpit.com/?pageView=live-nse-advance-decline-ratio-chart")
soup = BeautifulSoup(page.content)
adv = soup.select_one('a:-soup-contains("Advanced:")').next_sibling.strip()
dec = soup.select_one('a:-soup-contains("Declined:")').next_sibling.strip()
print(adv, dec)
If there are always 2 elements, then the simplest way would probably be to destructure the array of selected elements.
import requests
from bs4 import BeautifulSoup
page = requests.get("https://www.traderscockpit.com/?pageView=live-nse-advance-decline-ratio-chart")
soup = BeautifulSoup(page.content, "html.parser")
adv, dec = [elm.next_sibling.strip() for elm in soup.select(".advDec a") ]
print("Advanced:", adv)
print("Declined", dec)
I am on a scraping project and I am lookin to scrape from the following.
<div class="spec-subcat attributes-religion">
<span class="h5">Faith:</span>
<span>Christian</span>
<span>Islam</span>
</div>
I want to extract only Christian, Islam as the output.(Without the 'Faith:').
This is my try:
faithdiv = soup.find('div', class_='spec-subcat attributes-religion')
faith = faithdiv.find('span').text.strip()
How can I make this done?
There are several ways you can fix this, I would suggest the following - Find all <span> in <div> that have not the class="h5":
soup.select('div.spec-subcat.attributes-religion span:not(.h5)')
Example
import requests
html_text = '''
<div class="spec-subcat attributes-religion">
<span class="h5">Faith:</span>
<span>Christian</span>
<span>Islam</span>
</div>
'''
soup = BeautifulSoup(html_text, 'lxml')
', '.join([x.get_text() for x in soup.select('div.spec-subcat.attributes-religion span:not(.h5)')])
Output
Christian, Islam
I have a document which contains several div.inventory siblings.
<div class="inventory">
<span class="item-number">123</span>
<span class="cost">
$1.23
</span>
</div>
I would like to iterate over them to print the item number and link of the item.
123 http://linktoitem
456 http://linktoitem2
789 http://linktoitem3
How do I parse these two values after selecting the div.inventory element?
import requests
from bs4 import BeautifulSoup
htmlSource = requests.get(url).text
soup = BeautifulSoup(htmlSource)
matches = soup.select('div.inventory')
for match in matches:
#prints 123
#prints http://linktoitem
Also - what is the difference between the select function and find* functions?
You can find both items using find() relying on the class attributes:
soup = BeautifulSoup(data)
for inventory in soup.select('div.inventory'):
number = inventory.find('span', class_='item-number').text
link = inventory.find('span', class_='cost').a.get('href')
print number, link
Example:
from bs4 import BeautifulSoup
data = """
<body>
<div class="inventory">
<span class="item-number">123</span>
<span class="cost">
$1.23
</span>
</div>
<div class="inventory">
<span class="item-number">456</span>
<span class="cost">
$1.23
</span>
</div>
<div class="inventory">
<span class="item-number">789</span>
<span class="cost">
$1.23
</span>
</div>
</body>
"""
soup = BeautifulSoup(data)
for inventory in soup.select('div.inventory'):
number = inventory.find('span', class_='item-number').text
link = inventory.find('span', class_='cost').a.get('href')
print number, link
Prints:
123 http://linktoitem
456 http://linktoitem2
789 http://linktoitem3
Note the use of select() - this method allows to use CSS Selectors for searching over the page. Also note the use of class_ argument - underscore is important since class is a reversed keyword in Python.
