py-parse 0.1.2

A simplest HTML parsing library.

README

A simplest html parsing library.

Key features:

• no third-party dependencies
• no need to know CSS, Xpath or complicated rules to find element
• interaction with native python lambda syntax or function-predicate
• opportunity to work with damaged html
• ability to use element relations (find ancestor, descendant, siblings)
• standard find first element or find all by current filter

Installation

Via pip:

pip install py_parse

First example

Lets get src attribute (link) of the Google logo on google.com

import requests
from py_parse import parse

# get content of the google web page
content = requests.get('https://www.google.com/').text
# find first element with img-tag and 'alt' attribute equal to Google (logo)
google_logo = parse(content).find(lambda e: e.tag == 'img' and e.alt == 'Google')
# prints src attribute of the logo element
print(google_logo.src)

You will see following result

/images/branding/googlelogo/1x/googlelogo_white_background_color_272x92dp.png

If there is no element with current filter, you will get exception with filters text (if lamda was used)^ For code above lets say we use wrong filter

google_logo = parse(content).find(lambda e: e.tag == 'img' and e.alt == 'Wrong')

You will see following result

...traceback...
py_parse.exceptions.NoSuchElementError: No elements with current filter (e.tag == 'img' and e.alt == 'Wrong')

TODO - child, ancestor, sibling, descendant, mailformed html, check tags, autoclose
