Can I use Scrapy with BeautifulSoup?
------------------------------------
Yes, you can.
As mentioned :ref:`above <faq-scrapy-bs-cmp>`, `BeautifulSoup`_ can be used
for parsing HTML responses in Scrapy callbacks.
You just have to feed the response's body into a ``BeautifulSoup`` object
and extract whatever data you need from it.
Here's an example spider using BeautifulSoup API, with ``lxml`` as the HTML parser::
from bs4 import BeautifulSoup
import scrapy
class ExampleSpider(scrapy.Spider):
name = "example"
allowed_domains = ["example.com"]
start_urls = (
'http://www.example.com/',
)
def parse(self, response):
# use lxml to get decent HTML parsing speed
soup = BeautifulSoup(response.text, 'lxml')
yield {
"url": response.url,
"title": soup.h1.string
}
.. note::
``BeautifulSoup`` supports several HTML/XML parsers.
See `BeautifulSoup's official documentation`_ on which ones are available.
