CSS::Selector::Parser - parse CSS selectors to Perl data structures

VERSION

Top

version 0.002

SYNOPSIS

Top

  use CSS::Selector::Parser 'parse_selector';

  my @rules = parse_selector('#foo .bar, baz:quux');
  # [ { id => 'foo' }, { class => 'bar', combinator => ' ' } ]
  # [ { element => 'baz', pseudo => { quux => undef } ]

DESCRIPTION

Top

This module parses CSS selectors and gives back a series of Perl data structures corresponding to the selectors.

FUNCTIONS

Top

CSS::Selector::Parser uses Sub::Exporter. See its documentation for various ways to customize exporting.

parse_selector

  my @rules = parse_selector($selector);

CSS selectors are mapped to Perl data structures. Each set of selectors is returned as an arrayref of hashrefs (see SYNOPSIS for an example).

The hashrefs have:

element

foo in foo#bar.baz.

id

bar in foo#bar.baz. Note: NOT [id="..."].

class

baz in foo#bar.baz. Note: NOT [class="..."].

attr

A hashref of attribute selectors, each of which has a hashref of operators and values:

  parse_selector('[foo="bar"]')
  # [ { attr => { foo => { '=' => 'bar' } } } ]

Attribute selectors can also test for presence:

  parse_selector('[foo]')
  # [ { attr => { foo => undef } } ]

pseudo

A hashref of pseudo-classes and their contents, if present:

  parse_selector(':active:nth(2)')
  # [ { pseudo => { active => undef, nth => 2 } } ]

combinator

All hashrefs after the first will have this. One of <[ +]>>. See SYNOPSIS for an example.
