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

The function returns a two-dimensional array. The first array represents subselects 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 }
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 }

//TODO complete list

Options:

  • xmlMode: When enabled, tagnames will be case-sensitive (ie. the output won't be lowercased).
