Description
A simple way to transform a HTML file or URL to structured data. You only need to define the xpath to the element. Optionaly you can define functions to be applied after. You can easily write XPATH using the firebug extension, copy XPATH (I recommend edit the XPATH given by firebug, making it shorter).
Example
Import
>>> from html2data import HTML2Data
Create instance
>>> html = """<!DOCTYPE html><html lang="en"><head>
<meta charset="utf-8" />
<title>Example Page</title>
<link rel="stylesheet" href="css/main.css" type="text/css" />
</head>
<body>
<h1><b>Title</b></h1>
<div class="description">This is not a valid HTML
</body>
</html>"""
>>> h2d_instance = HTML2Data(html = html) #You can also create it from a url = url
Using XPATH config
One you have the object
>>> config = [
{'name': 'header_title', 'xpath': '//head/title/text()'},
{'name': 'body_title', 'xpath': '//h1/b/text()'},
{'name': 'description', 'xpath': '//div[@class="description"]/text()'},
]
>>> h2d_instance.parse(config = config)
{'header_title': 'Example Page', 'body_title': 'Title', 'description': 'This is not a valid HTML'}
Using CSS SELECTOR config
>>> config = [
{'name': 'header_title', 'css': 'head title'},
{'name': 'body_title', 'css': 'h1 b '},
{'name': 'description', 'css': 'div.description'},
]
>>> h2d_instance.parse(config = config)
{'header_title': 'Example Page', 'body_title': 'Title', 'description': 'This is not a valid HTML'}
Real life example
import urllib2
from html2data import HTML2Data
response = urllib2.urlopen('http://sil.senado.cl/cgi-bin/sil_ultproy.pl')
html = response.read()
config = [
{'name': 'fecha', 'css': 'td:nth-child(1)'},
{'name': 'id', 'css': 'td:nth-child(2) a'},
{'name': 'nombre', 'css': 'td:nth-child(3)'},
{'name': 'estado', 'css': 'td:nth-child(4)'},
]
html_instance = HTML2Data(html = html)
rows = html_instance.parse_one(css = 'td td tr', multiple = True, text = False)
for row_element in rows:
row_in_html = HTML2Data(tree = row_element)
print row_in_html.parse(config = config)
You will get something like:
{'nombre': 'Reforma Constitucional que restablece obligatoriedad del voto.', 'fecha': '24/11/2011', 'estado': 'En tramitación', 'id': '8062-07'}
..
{'nombre': 'Prohíbe el anatocismo.', 'fecha': '02/11/2011', 'estado': 'En tramitación', 'id': '8007-03'}
