Dude (dude uncomplicated data extraction) is a very simple framework for writing web scrapers using Python decorators.
The design, inspired by Flask, was to easily build a web scraper in just a few lines of code. Dude has an easy-to-learn syntax.
The simplest web scraper will look like this:
```python
from dude import select
@select(css="a")
def get_link(element):
return {"url": element.get_attribute("href")}
```
dude supports multiple parser backends:
- playwright
- lxml
- parsel
- beautifulsoup
- pyppeteer
- selenium
Geziyor is a blazing fast web crawling and web scraping framework.
It can be used to crawl websites and extract structured data from them.
Geziyor is useful for a wide range of purposes such as data mining, monitoring and automated testing.
Features:
- JS Rendering
- 5.000+ Requests/Sec
- Caching (Memory/Disk/LevelDB)
- Automatic Data Exporting (JSON, CSV, or custom)
- Metrics (Prometheus, Expvar, or custom)
- Limit Concurrency (Global/Per Domain)
- Request Delays (Constant/Randomized)
- Cookies, Middlewares, robots.txt
- Automatic response decoding to UTF-8
- Proxy management (Single, Round-Robin, Custom)
```python
from dude import select
"""
This example demonstrates how to use Parsel + async HTTPX
To access an attribute, use:
selector.attrib["href"]
You can also access an attribute using the ::attr(name) pseudo-element, for example "a::attr(href)", then:
selector.get()
To get the text, use ::text pseudo-element, then:
selector.get()
"""
@select(css="a.url", priority=2)
async def result_url(selector):
return {"url": selector.attrib["href"]}
# Option to get url using ::attr(name) pseudo-element
@select(css="a.url::attr(href)", priority=2)
async def result_url2(selector):
return {"url2": selector.get()}
@select(css=".title::text", priority=1)
async def result_title(selector):
return {"title": selector.get()}
@select(css=".description::text", priority=0)
async def result_description(selector):
return {"description": selector.get()}
