Converts numeric HTML entities and Unicode characters to nice, neat named HTML entities
Project description
Named HTML entities are much neater and much easier to comprehend than numeric entities. And because they fall within the ASCII range, they’re much safer to use in multiple contexts than Unicode and its various encodings (UTF-8 and such).
This module helps convert from numerical HTML entites and Unicode characters that fall outside the normal ASCII range into named entities.
Usage
Python 2:
from namedentities import named_entities, unescape u = u'both em\u2014and–dashes…' ne = named_entities(u) print "named: ", repr(ne) print "unicode:", repr(unescape(ne))
yields:
named: 'both em—and–dashes…' unicode: u'both em\u2014and\u2013dashes\u2026'
You can do just about the same thing in Python 3, but you have to use a print function rather than a print statement, and prior to 3.3, you have to skip the u prefix that marks a string literal as unicode to Python 2.x. (3.3 adds the u prefix back in as an optional, doesn’t-really-do-anything feature that nonetheless helps cross-version compatibility quite a bit.)
Recent Changes
The unescape(text) API, while long present, is now available for easy external consumption. It converts strings with HTML entities into strings with just Unicode.
Repackaged as a Python package, rather than independent modules.
Now successfully packaged for, and tests against, against Python 2.6, 2.7, and 3.3, as well as PyPy 2.0.2 (based on 2.7.3). Automated multi-version testing managed with the wonderful pytest and tox. Should also work under Python 2.5 and 3.2 releases, and PyPy 1.9, but those have been removed from “official support” because they are no longer supported in my testing environment. Time to upgrade!
Notes
Doesn’t attempt to encode <, >, or & (or their numerical equivalents) to avoid interfering with HTML escaping.
This is basically a packaging of Ian Beck’s work. Thank you, Ian!
Installation
pip install -U namedentities
To easy_install under a specific Python version (3.3 in this example):
python3.3 -m easy_install --upgrade namedentities
(You may need to prefix these with “sudo “ to authorize installation.)
