what is it ---------- A CSS Cascading Style Sheets library for Python.

Partly implements the DOM Level 2 Style Stylesheets and CSS interfaces. An implementation of the WD CSS Module: Namespaces which has no official DOM yet is included since v0.9.1.

changes since 0.9.2b4 --------------------- for full details see the relevant README file http://cssutils.googlecode.com/svn/tags/TAG_0.9.3a1/README.txt

Lots of thanks to Walter Dörwald who had quite an influence on this release (thinking, helping, coding).

from the README: - FEATURE: Implemented css.CSSValue, css.CSSPrimitiveValue and css.CSSValueList.

Not yet implemented are: - css.CSSPrimitiveValue.getCounterValue and css. Counter - css.CSSPrimitiveValue.getRGBColorValue and css.RGBColor - css.CSSPrimitiveValue.getRectValue and css.Rect

+ FEATURE: css.CSSValueList is iterable so may be used in a for loop + FEATURE: CSSValue has property ``cssValueTypeString`` which is the name of the relevant ``cssValueType``, e.g. "CSS_PRIMITIVE_TYPE". Mainly useful for debugging. + FEATURE: CSSPrimitiveValue has property ``primitiveTypeString`` which is the name of the relevant ``primitiveType``, e.g. "CSS_PX". Mainly useful for debugging. + CSSValue has an init Parameter ``_propertyname`` to set a context property for validation. If none is set the value is always invalid. **THIS MAY CHANGE!**

- FEATURE (**experimental**): CSSStyleDeclaration is iterable now. The iterator returns *all* properties set in this style as objects with properties ``name``, ``cssValue`` and ``priority``. Calling CSSStyleDeclaration.item(index) on the other hand simply returns a property name and also only the normalized name (once). Example::

sheet = cssutils.parseString('a { color: red; c\olor: blue; left: 0 !important }') for rule in sheet.cssRules: style = rule.style for property in style: name = property.name cssValue = property.cssValue priority = property.priority print name, '=', cssValue.cssText, priority

# prints: # color = red # c\olor = blue # left = 0 !important

for i in range(0, style.length): name = style.item(i) cssValue = style.getPropertyCSSValue(name) priority = style.getPropertyPriority(name) print name, '=', cssValue.cssText , priority

# prints: # color = blue # left = 0 !important

- FEATURE (**experimental**): added ``CSSStyleSheet.replaceUrls(replacer)`` which may be used to adjust all "url()" values in a style sheet (currently in CSSStyleDeclaration and CSSImportRules).

- FEATURE: added ``CSSStyleDeclaration.getCssText(separator=None)`` which returns serialized property cssText, each property separated by given ``separator`` which may e.g. be u'' to be able to use cssText directly in an HTML style attribute. ";" is always part of each property (except the last one) and can **not** be set with separator!

- FEATURE: ``href`` and ``media`` arguments can now be passed to ``parse()`` and ``parseString()`` functions and methods. This sets the appropriate attributes on the generated stylesheet objects.

- FEATURE: CSSMediaRule has an init parameter ``mediaText`` synchronous to CSSImportRule now

- FEATURE: The ``MediaList`` constructor can now be passed a list of media types.

- FEATURE: ``CSSRule`` and subclasses have a property ``typeString`` which is the name of the relevant ``type``, e.g. ``STYLE_RULE``. Mainly useful for debugging.

- FEATURE: ``cssutils.serialize.Preferences`` has a new option ``lineSeparator`` that is used as linefeed character(s). May also be set to ``u''`` for ``CSSStyleDeclareation.cssText'`` to be directly usable in e.g. HTML style attributes

+ API CHANGE (internal): renamed serializers method ``do_stylesheet`` to ``do_CSSStyleSheet``

- BUGFIX (issue #9): Parsing of empty ``url()`` values has been fixed - BUGFIX: Handling of linenumbers in the serializer has been fixed. - BUGFIX (minor): removed debug output in CSSStyleDeclaration

+ CHANGE (experimental!): CSSStyleDeclaration.getPropertyCSSValue() for shorthand properties like e.g. ``background`` should return None. cssutils returns a CSSValueList in these cases now. Use with care as this may change later

+ CHANGE: CSSValue default cssText is now ``u""`` and not ``u"inherit"`` anymore

+ CHANGE: ``css.CSSStyleDeclaration.cssText`` indents its property not anymore.

+ CHANGE: ``cssutils.serialize.CSSSerializer`` has been refactored internally to support the lineSeparator option.

+ CHANGE: The Selector and SameNamePropertyList (which might be renamed as it is experimental) class are now available from cssutils.css too.

+ CHANGE: Tokenizer strips HTML comment tokens CDO and CDC from tokenlist now.

+ CHANGE: Added __repr__ and __str__ methods to most classes. __str__ reports e.g. ``<cssutils.css.CSSImportRule object href=None at 0xaaa870>``, __repr__ e.g. ``cssutils.css.CSSImportRule(href=None, mediaText=u'all')`` which is a valid contructor for the object in most cases (which might not be complete for all init parameter for all classes like in this case though). The following details are included:

css - CSSStyleSheet shows the title and href - CSSCharsetRule shows the encoding - CSSCharsetRule shows the cssText (not in __str__ though) - CSSImportRule shows the href and the MediaList mediaText - CSSMediaRule shows the MediaList mediaText - CSSNameSpaceRule shows the prefix and uri - CSSPageRule shows the selectorText - CSSStyleRule shows the selectorText - CSSUnknownRule shows nothing special - CSSStyleDeclaration shows the number of properties set for __str__ but an empty CSSStyleDeclaration constructor for __repr__ as showing cssText might be way too much - SameNamePropertyList shows the name - CSSValue, CSSPrimitiveValue show the actual value for __repr__, some details for __str__ - CSSValueList shows an __repr__ which is **not** possible to ``eval()`` and some details for __str__ - _Property shows infos but should be used directly for now anyway! - Selector the selectorText

stylesheets - MediaList shows the mediaText
