API

CSSwhat(selector, options) - Parses str, 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:

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:

• xmlMode: When enabled, tag names will be case-sensitive (meaning they won't be lowercased).
