what is it ---------- A Python package to parse and build CSS Cascading Style Sheets. Partly implement the DOM Level 2 CSS interfaces. Additional some cssutils only convenience and (hopefully) more pythonic methods are integrated. Thanks to Cory Dodt for helpful suggestions and some code patches and to David Mertz for his book ”Text Processing in Python“ and the included statemachine.py which is used for cssutils Cssutils are far from being perfect or even complete, if you find bugs or have suggestions or problems please contact me. changes in this release ----------------------- new cssunknownrule.UnknownRule (moved out of module cssrule) parser now creates Unknown At-Rules in the resulting StyleSheet. they are no longer just dumped and reported in the parser log. license ------- cssutils is published under the LGPL. download -------- download cssutils v0.53 - 040418 from http://cthedot.de/cssutils/ Needs Python 2.3. Uses xml.dom.DOMException and subclasses so may need PyXML. Tested with Python 2.3.3 on Windows XP with PyXML 0.8.3 installed. examples -------- parse a CSSStyleSheet Normally a CSS parser should ignore errors in a CSS stylesheet. So the default instantiation of CSSParser (parameter raiseExceptions=False) does not raise any exceptions but writes all errors in a parsed CSS to a log file now. You might provide your own log with parameter log=YOURLOG. This example does not use the log but would stop on the first error. from cssutils.cssparser import CSSParser p = CSSParser(raiseExceptions=True) try: css = p.parseString('body { color :red }') # or p.parse('filename.css') except xml.dom.DOMException, e: print e css.pprint() # prettyprinter s.b. outputs body { color: red; } build a new CSSStyleSheet Not all interfaces of DOM Level 2 CSS are implemented yet. But they will be provided in future versions of the cssbuilder module. The following is a simple example how to build a CSSStyleSheet object. from cssutils.cssbuilder import * # init CSSStylesheet css = StyleSheet() # build a rule r = StyleRule() r.addSelector('body') r.addSelector('b') # a second one d = StyleDeclaration() d.setProperty('color', 'red') # old addProperty is DEPRECATED r.setStyleDeclaration(d) # build @media Rule mr = MediaRule(' print, tv ') d = StyleDeclaration() d.setProperty('color', '#000') r = StyleRule('body', d) mr.addRule(r) # compose stylesheet css.addComment('basic styles') css.addComment('styles for print or tv') css.addRule(mr) css.insertRule(r, 1) # output css.pprint(2) outputs /* basic styles */ body, b { color: red; } /* styles for print or tv */ @media print, tv { body { color: #000; } } christof hoeke http://cthedot.de <P><A HREF="http://cthedot.de/cssutils/">cssutils 0.53</A> - a CSS Cascading Style Sheets library for Python (18-Apr-04)
