API

CSSwhat.parse(str, options) - Parses str, optionally with the passed options.

The function returns a two-dimensional array. The first array represents selectors separated by commas (eg. sub1, sub2), the second contains the relevant tokens for that selector. Possible token types are:

name attributes example output
tag name div { type: 'tag', name: 'div' }
universal - * { type: 'universal' }
pseudo name, data :name(data) { type: 'pseudo', name: 'name', data: 'data' }
pseudo name, data :name { type: 'pseudo', name: 'name', data: null }
pseudo-element name ::name { type: 'pseudo-element', name: 'name' }
attribute name, action, value, ignoreCase [attr] { type: 'attribute', name: 'attr', action: 'exists', value: '', ignoreCase: false }
attribute name, action, value, ignoreCase [attr=val] { type: 'attribute', name: 'attr', action: 'equals', value: 'val', ignoreCase: false }
attribute name, action, value, ignoreCase [attr^=val] { type: 'attribute', name: 'attr', action: 'start', value: 'val', ignoreCase: false }
attribute name, action, value, ignoreCase [attr$=val] { type: 'attribute', name: 'attr', action: 'end', value: 'val', ignoreCase: false }
child - > { type: 'child' }
parent - < { type: 'parent' }
sibling - ~ { type: 'sibling' }
adjacent - + { type: 'adjacent' }
descendant - { type: 'descendant' }

Options:

  • lowerCaseTags: When false, tag names will not be lowercased. Defaults to true.
  • lowerCaseAttributeNames: When false, attribute names will not be lowercased. Defaults to true.
  • xmlMode: When true, xmlMode implies both lowerCaseTags and lowerCaseAttributeNames are set to false.

CSSwhat.stringify(selector) - Turns selector back into a string.
