This library intends to make parsing HTML (e.g. scraping the web) as
simple and intuitive as possible.

When using this library you automatically get:

- Full JavaScript support!
- CSS Selectors (a.k.a jQuery-style, thanks to PyQuery).
- XPath Selectors, for the faint at heart.
- Mocked user-agent (like a real web browser).
- Automatic following of redirects.
- Connection–pooling and cookie persistience.
- The Requests experience you know and love, with magical parsing abilities.

.. Other nice features include:

    - Markdown export of pages and elements.


Installation
============

.. code-block:: shell

    $ pipenv install requests-html
    ✨🍰✨

Only later versions of **Python 3** are supported.


Tutorial & Usage
================

Make a GET request to 'python.org', using Requests:

.. code-block:: pycon

    >>> from requests_html import HTMLSession
    >>> session = HTMLSession()

    >>> r = session.get('https://python.org/')

Grab a list of all links on the page, as–is (anchors excluded):

.. code-block:: pycon

    >>> r.html.links

Select an element with a CSS Selector:

.. code-block:: pycon

    >>> about = r.html.find('#about', first=True)

Grab an element's text contents:

.. code-block:: pycon

    >>> print(about.text)
    About
    Applications
    Quotes
    Getting Started
    Help
    Python Brochure

Introspect an Element's attributes:

.. code-block:: pycon

    >>> about.attrs
    {'id': 'about', 'class': ('tier-1', 'element-1'), 'aria-haspopup': 'true'}

Render out an Element's HTML:

.. code-block:: pycon

    >>> about.html
    '<li aria-haspopup="true" class="tier-1 element-1 " id="about">\n<a class="" href="/about/" title="">About</a>\n<ul aria-hidden="true" class="subnav menu" role="menu">\n<li class="tier-2 element-1" role="treeitem"><a href="/about/apps/" title="">Applications</a></li>\n<li class="tier-2 element-2" role="treeitem"><a href="/about/quotes/" title="">Quotes</a></li>\n<li class="tier-2 element-3" role="treeitem"><a href="/about/gettingstarted/" title="">Getting Started</a></li>\n<li class="tier-2 element-4" role="treeitem"><a href="/about/help/" title="">Help</a></li>\n<li class="tier-2 element-5" role="treeitem"><a href="http://brochure.getpython.info/" title="">Python Brochure</a></li>\n</ul>\n</li>'



Select Elements within Elements:

.. code-block:: pycon

    >>> about.find('a')
    [<Element 'a' href='/about/' title='' class=''>, <Element 'a' href='/about/apps/' title=''>, <Element 'a' href='/about/quotes/' title=''>, <Element 'a' href='/about/gettingstarted/' title=''>, <Element 'a' href='/about/help/' title=''>, <Element 'a' href='http://brochure.getpython.info/' title=''>]

Search for links within an element:

.. code-block:: pycon

    >>> about.absolute_links
    {'http://brochure.getpython.info/', 'https://www.python.org/about/gettingstarted/', 'https://www.python.org/about/', 'https://www.python.org/about/quotes/', 'https://www.python.org/about/help/', 'https://www.python.org/about/apps/'}


Search for text on the page:

.. code-block:: pycon

    >>> r.html.search('Python is a {} language')[0]
    programming

More complex CSS Selector example (copied from Chrome dev tools):

.. code-block:: pycon

    >>> r = session.get('https://github.com/')
    >>> sel = 'body > div.application-main > div.jumbotron.jumbotron-codelines > div > div > div.col-md-7.text-center.text-md-left > p'

    >>> print(r.html.find(sel, first=True).text)
    GitHub is a development platform inspired by the way you work. From open source to business, you can host and review code, manage projects, and build software alongside millions of other developers.

XPath is also supported:

.. code-block:: pycon

   >>> r.html.xpath('a')
   [<Element 'a' class='btn' href='https://help.github.com/articles/supported-browsers'>]

JavaScript Support
==================

Let's grab some text that's rendered by JavaScript:

.. code-block:: pycon

    >>> from requests_html import BrowserHTMLSession
    >>> session = BrowserHTMLSession()

    >>> r = session.get('http://python-requests.org')
    >>> r.html.search('Python 2 will retire in only {months} months!')['months']
    '<time>25</time>'


Using without Requests
======================

You can also use this library without Requests:

.. code-block:: pycon

    >>> from requests_html import HTML
    >>> doc = """<a href='https://httpbin.org'>"""

    >>> html = HTML(html=doc, url='fakeurl', default_encoding='utf-8')
    >>> html.links
    {'https://httpbin.org'}
