\QueryPath\CSSScanner

__construct()

__construct(\QueryPath\CSS\InputStream  $in) 

Given a new input stream, tokenize the CSS selector string.

Parameters

position()

position() 

Return the position of the reader in the string.

peek()

peek() : \QueryPath\CSS\char

See the next char without removing it from the stack.

Returns

Returns the next character on the stack.

nextToken()

nextToken() : integer

Get the next token in the input stream.

This sets the current token to the value of the next token in the stream.

Returns

Returns an int value corresponding to one of the Token constants, or FALSE if the end of the string is reached. (Remember to use strong equality checking on FALSE, since 0 is a valid token id.)

getNameString()

getNameString() 

Get a name string from the input stream.

A name string must be composed of only characters defined in Token:char: -_a-zA-Z0-9

getQuotedString()

getQuotedString() 

This gets a string with any legal 'string' characters.

See CSS Selectors specification, section 11, for the definition of string.

This will check for string1, string2, and the case where a string is unquoted (Oddly absent from the "official" grammar, though such strings are present as examples in the spec.)

Note: Though the grammar supplied by CSS 3 Selectors section 11 does not address the contents of a pseudo-class value, the spec itself indicates that a pseudo-class value is a "value between parenthesis" [6.6]. The examples given use URLs among other things, making them closer to the definition of 'string' than to 'name'. So we handle them here as strings.
