Hi,
I would like to scrap a private webpage where I need to be logged in.
Is there a way to do that?
Thank you
Hi how can I handle pagination for example if I want to fetch comments and reviews.
And is there a way to detect/handle consecutive pages other than by listing them like how general scrapers would have a click function to move to different pages or actions.
Hello! Thank you so much for sharing your work!
I wanted to ask, if i trained my model on some website, then this website will change the website structure and styling , will it still work? Can I get the same data? or I will be needed to re-train it again?
I want to scrape information from all the pages of a website, Is there a way that it will go to next page automatically and scrape it?
I followed all instruction and run the sample program using the AutoScraper
as shown below
from autoscraper import AutoScraper
url = 'https://stackoverflow.com/questions/2081586/web-scraping-with-python'
wanted_list = ["What are metaclasses in Python?"]
scraper = AutoScraper()
result = scraper.build(url, wanted_list )
print(result)
But I get the follwoing error

I read a previous post that mentioned capability for the HTML parameter, in which I could render a JS application using another tool (BS or Selenium) and pass in the HTML data for AutoScraper to parse. Does anyone have steps or documentation on how to use this parameter?
I'm working with a legacy Chinese site with BIG5 text encoding, and I'm not able to set text encoding by passing arguments through request_args
, because requests don't support it.
So the results I get was garbled, like this: '¡ ̧ÔÚÕâ ̧öÊÀ1⁄2ç ̧æÖÕÒÔÇ°©¤©¤A¡1-promise/result-'
.
Encoding can only be set by writing to the encoding
property of requests object (According to this).
So maybe adding an encoding
param and set encoding in _get_soup
in auto_scraper.py
would be a good idea.
I‘m sorry to add this issue, I dont konw whether this is an issue.
In my code.I dont want to remove the duplicate result,and I had tried to commented out some code.But it seems doesn't work,so I add this issue.
sorry for this issue again.Pls tell me If this is not an issue,I will delete this.
Perhaps we want to let the scraper find the data we know will be in the page, we just don't know the value of it. Using your first example for the Stack Overflow related questions, what if we could instead modify the list as such:
wanted_list = ["Related"]
and this would still return the same output:
'How do I merge two dictionaries in a single expression in Python (taking union of dictionaries)?', 'How to call an external command?',..., 'Why is “1000000000000000 in range(1000000000000001)” so fast in Python 3?'
Similarly, for the stock price example we need to know the stock's value ahead of time. What if we want to grab those values using the scraper?
wanted_list = ["Previous Close", "Day's Range"]
This also allows get_result_exact to feed us the same values given another stock's yahoo url.
I'm not familiar enough with BeautifulSoup to know how simple it would be to parse out these elements' values, but it could be worth thinking about.
Cheers!

Most of the pages you demo on are dynamic, so some of the quoted text disappears. Can you pick sites that don't change as ofter.
Tested with autoscraper-1.1.6
When calling the build method with wanted_dict, the method behaves badly as it treats the searched string as an array of individual letters. The culprit is around l.204 of auto_scraper.py as the data structure does not behave the same as when you use the wanted_list option.
Besides this, I find the work done so far super interesting and promising. Keep up the good work.
R.
When trying to find anything that contains a .
in it I get no results.
url = 'https://pastebin.com/APSMFRLL'
# We can add one or multiple candidates here.
# You can also put urls here to retrieve urls.
wanted_list = ["."]
scraper = AutoScraper()
result = scraper.build(url, wanted_list)
print(result)
I would've expected to get:
one.two
three.four
five.six
seven.eight
Maybe I'm not doing something correctly perhaps.
This site is consistent and well-structured with easily located selectors but autoscraper
struggles with scraping the data. I trained it with a few examples which found the data successfully but subsequent attempts to scrape other pages yields missing data even though the markup is the same for these pages as the training pages.
from autoscraper import AutoScraper
scraper = AutoScraper()
scraper.build("https://www.weedsta.com/strains/blue-dream", ["Blue Dream", "Hybrid", "24.49%", "0.19%", "10 Reviews"], update=True)
scraper.build("https://www.weedsta.com/strains/trainwreck", ["Trainwreck", "Sativa", "18.63%", "0.53%", "3 Reviews"], update=True)
scraper.build("https://www.weedsta.com/strains/sour-diesel", ["Sour Diesel", "Sativa", "22.2%", "0.31%", "8 Reviews"], update=True)
Here's an example where you can see that the percentages are not returned.
>>> scraper.get_result_similar('https://www.weedsta.com/strains/banana-kush', grouped=True)
{'rule_dt56': ['Banana Kush'], 'rule_l8fu': ['Banana Kush'], 'rule_7m0b': [], 'rule_fq5s': ['1 Reviews'], 'rule_4lqv': [], 'rule_bq2d': [], 'rule_mgmx': [], 'rule_pshq': [], 'rule_cnvq': ['Banana Kush'], 'rule_bmx8': ['Banana Kush'], 'rule_3npf': [], 'rule_7ko7': [], 'rule_tfnf': [], 'rule_ia0h': []}

I am trying to export a localhost website that is generated with this project:
https://github.com/HBehrens/puncover
The project generates a localhost website, and each time the user interacts clicks a link the project receives a GET request and the website generates the HTML. This means that the HTML is generated each time the user access a link through their browser. At the moment the project does not export the website to html or pdf. For this reason I want to know how could I recursively get all the hyperlinks and then generate the HTML version. Would this be possible with autoscraper?
Hello! @alirezamika
I wanted to ask what to do if the text in the wanted list is no longer available in the website !
from autoscraper import AutoScraper
scrapper=AutoScraper()
scrape_data1=[
("https://theprint.in",["Japan envoy holds talks with senior Taliban members in Kabul"]),
("https://theprint.in",["India records 9,119 new Covid cases, active infections lowest in 539 days"]),
("https://theprint.in",["Farm laws debate missed a lot. Neither supporters nor Modi govt identified the real problem"]),
("https://theprint.in",["Punjab’s Dalits are shifting state politics, flocking churches, singing Chamar pride"]),
]
for get_url,data in scrape_data1:
scrapper.build(url=get_url,wanted_list=data,update=True)
Main_news=scrapper.get_result_similar(url="https://theprint.in",grouped=True, group_by_alias=True,unique=True)
print(Main_news)
Here in the above code scrapes a news website but if i run it after few hours when the news get updated , scrapper returns
{}
or someting else related to the text found!
i mean i want to know how to optimize the code for dynamic websites where the text gets updated !
Thanks for creating such a cool project! It looks like it's exactly what I need, but I'm having trouble getting it to work for Github issue numbers.
Example code with this own project's issues page
from autoscraper import AutoScraper
url = 'https://github.com/alirezamika/autoscraper/issues?q=is%3Aissue'
wanted_list = ["#47"]
scraper = AutoScraper()
result = scraper.build(url, wanted_list)
print(result)
The result here is blank, and checking the stack_list, there is nothing there. The formatting for the element is a bit strange with lots of whitespace and newlines, so I tried copying the whole element in directly with triple parenthesis, but that has the same result.
wanted_list = """
#47
by """
Which when evaluated by python becomes
['\n #47\n by ']
Originally I also tried just using the number, as that would be the most convenient, but no beans. I was able to get it to work easily with the actual text of the issue, so I fear it's something weird with the way it's formatted.
Is this an issue with whitespace, or am I messing up something basic? Thanks!
The build returns blank for this url:
https://www.ptwxz.com/html/11/11014/
from autoscraper import AutoScraper
scraper = AutoScraper()
url = 'https://www.ptwxz.com/html/11/11014/'
wanted_list = ['第一章']
scraper.build(url, wanted_list)
print(scraper.stack_list)
url1 = 'https://www.ptwxz.com/html/9/9108/'
print(scraper.get_result_similar(url1))

how does this tool work with authentication? i'm interested in using with content behind a shibboleth saml login.. so i need to store session variables in the process
this is a great project but when i open a proxy, nothing worked. help please.
When our target value is a large block of text, it becomes messy.
Instead can a feature be added so that we can define the text shortly?
For example:
Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua. Ut enim ad minim veniam, quis nostrud exercitation ullamco laboris nisi ut aliquip ex ea commodo consequat. Duis aute irure dolor in reprehenderit in voluptate velit esse cillum dolore eu fugiat nulla pariatur. Excepteur sint occaecat cupidatat non proident, sunt in culpa qui officia deserunt mollit anim id est laborum
can be defined as:
Lorem ipsum(...)est laborum
What title says. I've been banned from a website after a few tests and was wondering if there's a solution to this.
Thanks!
I tried using autoscraper to scrape items from the hackernews home page. The scraper had issues with the nonbreaking space in the comments link on each list item. I was eventually able to workaround the issue by using '\xa0' in the wanted_list string. That matched the comments field but then returned incorrect results anyway. My guess is that something is not matching the nonbreaking space in the "stack" analysis (but I didn't invest the time to find the root cause).
This project is an interesting idea, but I recommend unit tests and some documentation about the matching algorithm to help users help you with diagnosing bugs.
Hello,
I am really delighted with this fantastic module. However I want to signal a lillte annoying bug:
I do suspect that since the head summary is align/centered and the other artcile summaries are align/left this might cause this skipping.
Thank You indeed, all te best

I was looking over the code for this project and am impressed with it's simplicity in design and brilliant approach to this problem. However, one thing that jumped out to me was the lack of asynchronous methods to allow for a huge speed increase, especially as the number of pages to scrape increases. I am quite familiar with the standard libraries used to meet this goal and propose the following changes:
Let me know your thoughts and if you're interested in the idea. The performance gains would be immense! Thanks!
1. Subclass AutoScraper
with AsyncAutoScraper
, which would require the packages aiohttp
, aiofiles
, and aiosql
along with a few others purely optionally to increase speed - uvloop
, brotlipy
, cchardet
, and aiodns
2. Refactor the _get_soup
method by extracting an async
method to download HTML asynchronously using aiohttp
3. Refactor the get_results*
and _build*
functions to also be async
(simply adding the keyword) and then making sure to call them by using a multiprocessing/threading pool
get_*
functions should handle the calling of these in an executor set to aforementioned poolconcurrent.futures.*
4. Use aiofiles
for the save
method to be able to export many individual JSON files quickly if desired, same for the load
method if multiple sources are being used
5. Add functionality for exporting to an SQL database asynchronously using aiosql
Not very reasonable, a lot of things change

Hi, when i launch : python3 autoscraper.py,

Trying to scrap email address from any given website.
It returns empty list.
How it can be used to scrap all the email gives on website.
This is my code
from autoscraper import AutoScraper

scraper = AutoScraper()
wanted_list = ["Many of our development partners are selling arms to Myanmar: Foreign Minister"]
scraper1 = AutoScraper()
result = scraper.build(url, wanted_list)
print(result)
This is the result
I am getting the value of candidate i.e. wanted_list = ["Many of our development partners are selling arms to Myanmar: Foreign Minister"]
as result.
I am new to autoscraper (actually I am just trying out from today). Is this the usual result I should hope for or do I get the content of whole webpage ?
i tried to scrape the webpage but the results are zero 👍

Output Results are none
@alirezamika can you guide whats the issue:
As of now, the rules are formed at once based on the targets specified in wanted_list
and the stack list is generated for those targets. Sometimes there will be scenarios where I have to update the existing stack list with new rules learnt from different set of targets on the same URL. As seen in the build
method, you create a new stack list every time a build method is called. Provide an update
method, that updates the stack list simply by appending the new rules learnt from new set of targets.
This will be very useful functionality because it will allow developers to incrementally add new targets by retaining the older rules.
I am dealing with Q&A pages that some paragraphs contains extra spaces before and after the span (on inspecting the source), while some other span do not. E.g.:
(With extra space) https://www.sfc.hk/en/faqs/intermediaries/licensing/Associated-entities#0FCC1339F7B94DF69DD1DF73DB5F7DCA
(No extra space) https://www.sfc.hk/en/faqs/intermediaries/licensing/Family-Offices#F919B6DCE05349D8A9E8CEE8CA9C7750
As a result it seems like a model trained with the prior would not predict latter as similar. In fact even during the "build" process question with extra space don't treat other without space as similar.
Another question is on the expanded part of the text (the "A: " answer text). It doesn't expand unless a "+" sign is clicked. In that case is there anyway to get Exact result including the answer part?
Thanks for the great work.
add URL with save & load function so that we don't need to build or remember the URL

Hi, I can't get price from this url, even though I try to add request header to it.

scraper = AutoScraper()
s.get(url, headers=scraper.request_headers)
result = scraper.build(url, wanted_list, request_args={'cookies': s.cookies.get_dict()})

How can I get the price?
