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.
