Parse 
This package contains several lexers and parsers written in Go. All subpackages are built to be streaming, high performance and to be in accordance with the official (latest) specifications.
The lexers are implemented using buffer.Lexer in https://github.com/tdewolff/buffer and the parsers work on top of the lexers. Some subpackages have hashes defined (using Hasher) that speed up common byte-slice comparisons.
CSS
This package is a CSS3 lexer and parser. Both follow the specification at CSS Syntax Module Level 3. The lexer takes an io.Reader and converts it into tokens until the EOF. The parser returns a parse tree of the full io.Reader input stream, but the low-level Next function can be used for stream parsing to returns grammar units until the EOF.
HTML
This package is an HTML5 lexer. It follows the specification at The HTML syntax. The lexer takes an io.Reader and converts it into tokens until the EOF.
JS
This package is a JS lexer (ECMA-262, edition 6.0). It follows the specification at ECMAScript Language Specification. The lexer takes an io.Reader and converts it into tokens until the EOF.
JSON
This package is a JSON parser (ECMA-404). It follows the specification at JSON. The parser takes an io.Reader and converts it into tokens until the EOF.
SVG
This package contains common hashes for SVG1.1 tags and attributes.
XML
This package is an XML1.0 lexer. It follows the specification at Extensible Markup Language (XML) 1.0 (Fifth Edition). The lexer takes an io.Reader and converts it into tokens until the EOF.

Constants ¶

Variables ¶
var ErrBadDataURI = errors.New("not a data URI")
ErrBadDataURI is returned by DataURI when the byte slice does not start with 'data:' or is too short.
Functions ¶
func EqualFold ¶
EqualFold returns true when s matches case-insensitively the targetLower (which must be lowercase).
func IsAllWhitespace ¶
IsAllWhitespace returns true when the entire byte slice consists of space, \n, \r, \t, \f.
func IsWhitespace ¶
IsWhitespace returns true for space, \n, \r, \t, \f.
func Mediatype ¶
Mediatype parses a given mediatype and splits the mimetype from the parameters. It works similar to mime.ParseMediaType but is faster.
func Number ¶
Number returns the number of bytes that parse as a number of the regex format (+|-)?([0-9]+(\.[0-9]+)?|\.[0-9]+)((e|E)(+|-)?[0-9]+)?.
func QuoteEntity ¶
QuoteEntity parses the given byte slice and returns the quote that got matched (' or ") and its entity length.
func ReplaceMultipleWhitespace ¶ added in v1.1.0
ReplaceMultipleWhitespace replaces character series of space, \n, \t, \f, \r into a single space or newline (when the serie contained a \n or \r).
func TrimWhitespace ¶
TrimWhitespace removes any leading and trailing whitespace characters.
