htmllaundry Description

Simple HTML cleanup utilities The htmllaundry package contains several handy Python methods to cleanup HTML markup or perform other common changes. The cleanup is strict enough to be able to clean HTML pasted from MS Word or Apple Pages. This package also contains integration code for z3c.form to provide fields that automatically sanitize HTML on save.The implementation is based on the Cleaner class from lxml.Cleanup routinesAll cleanup routines can be invoked through the single sanitize function. This functions takes an input string as input and will return a cleaned up version of that string. Here is a simple example:>>> from htmllaundry import sanitize>>> sanitize('Hello, < em >world< /em >')'< p >Hello, < em >world< /em >< /p >'The sanitize method takes an extra optional parameter with a lxml Cleaner instance, which can be used to use different filtering rules. htmllaundry includes three cleaners: * htmllaundry.cleaners.DocumentCleaner, which is the default cleaner. This cleaner will allow most safe tags, while stripping out inline styles and insecure markup. * htmllaundry.cleaners.LineCleaner is a more strict cleaner which only allows a few inline elements. This is useful in places where you only want to accept single-line input, for example in document titles. * htmllaundry.cleaners.CommentCleaner only allows a very limited set of HTML elements, and is designed to be useful for user provided comments.If you want to go all the way you can also use StripMarkup to strip all markup from your input:>>> from htmllaundry import StripMarkup>>> StripMarkup('Hello, < em >world< /em >')'Hello, world'z3c.form integrationIf you want to use the z3c.form integration you should use the z3cform extra for this package:install_requires= ... ],In addition you will need to load the ZCML. In your configure.zcml add a line like this:< include package="htmllaundry" / >You can then use the HtmlText field type in your schemas. For example:from zope.interface import Interfacefrom zope import schemafrom htmllaundry.z3cform import HtmlTextclass IDocument(Interface): title = schema.TextLine( title = _(u"Title"), required = True) description = HtmlText( title = _(u"Description"), required = True)Please note that using HtmlText will not automatically give you a WYSYWIG widget. Requirements: · Python What's New in This Release: · Fix a typo in the documentation. · Strip trailing breaks.
