NAME
CSS::Object - CSS Object Oriented
SYNOPSIS
use CSS::Object;VERSION
v0.1.1DESCRIPTION
CSS::Object is a object oriented CSS parser and manipulation interface.
CONSTRUCTOR
new
To instantiate a new CSS::Object object, pass an hash reference of following parameters:
- debug
-
This is an integer. The bigger it is and the more verbose is the output.
- format
-
This is a CSS::Object::Format object or one of its child modules.
- parser
-
This is a CSS::Object::Parser object or one of its child modules.
EXCEPTION HANDLING
Whenever an error has occurred, CSS::Object will set a Module::Generic::Exception object containing the detail of the error and return undef.
The error object can be retrieved with the inherited "error" in Module::Generic method. For example:
my $css = CSS::Object->new( debug => 3 ) || die( CSS::Object->error );METHODS
add_element
Provided with a CSS::Object::Element object and this adds it to the list of css elements.
It uses an array object "elements" which is an Module::Generic::Array object.
add_rule
Provided with a CSS::Object::Rule object and this adds it to our list of rules. It returns the rule object that was added.
as_string
This will return the css data structure, currently registered, as a string.
It takes an optional CSS::Object::Format object as a parameter, to control the output. If none are provided, it will use the default one calling "format"
builder
This returns a new CSS::Object::Builder object.
charset
This sets or gets the css charset. It stores the value in a Module::Generic::Scalar object.
elements
Sets or gets the array of CSS elements. This is a Module::Generic::Array object that accepts only CSS::Object::Element objects or its child classes, such as CSS::Object::Rule, CSS::Object::Comment, etc
format
Sets or gets a CSS::Object::Format object. See "as_string" below for more detail about their use.
CSS::Object::Format objects control the stringification of the css structure. By default, it will return the data in a string identical or at least very similar to the one parsed if it was parsed.
get_rule_by_selector
Provided with a selector and this returns a CSS::Object::Rule object or an empty string.
load_parser
This will instantiate a new object based on the parser name specified with "parser" or during css object instantiation.
It returns a new CSS::Object::Parser object, or one of its child module matching the "parser" specified.
new_comment

return( $css->new_comment( $array_ref_of_comment_ilnes ) );new_property

new_value
This takes a property value and returns a new CSS::Object::Value object.
parse_string
Provided with some css data and this will instantiate the "parser", call "parse_string" in CSS::Object::Parser and returns an array of CSS::Object::Rule objects. The array is an array object from Module::Generic::Array and can be used as a regular array or as an object.
parser
Sets or gets the CSS::Object::Parser object to be used by "parse_string" to parse css data.
A valid parser object can be from CSS::Object::Parser or any of its sub modules.
It returns the current parser object.
purge
This empties the array containing all the CSS::Object::Rule objects.
read_file
Provided with a css file, and this will load it into memory and parse it using the parser name registered with "parser".
It can also take an array reference of css files who will be each fed to "read_file"
It returns the CSS::Object used to call this method.
read_string
Provided with some css data, and this will call "parse_string". It also accepts an array reference of data.
