Struct Decoder

opensca/sca/java/xml/xml.go:148–216

A Decoder represents an XML parser reading a particular input stream. The parser assumes that its input is encoded in UTF-8.

// A Decoder represents an XML parser reading a particular input stream.
// The parser assumes that its input is encoded in UTF-8.
type Decoder struct {
	// Strict defaults to true, enforcing the requirements
	// of the XML specification.
	// If set to false, the parser allows input containing common
	// mistakes:
	//	* If an element is missing an end tag, the parser invents
	//	  end tags as necessary to keep the return values from Token
	//	  properly balanced.
	//	* In attribute values and character data, unknown or malformed
	//	  character entities (sequences beginning with &) are left alone.
	//
	// Setting:
	//
	//	d.Strict = false
	//	d.AutoClose = xml.HTMLAutoClose
	//	d.Entity = xml.HTMLEntity
	//
	// creates a parser that can handle typical HTML.
	//
	// Strict mode does not enforce the requirements of the XML name spaces TR.
	// In particular it does not reject name space tags using undefined prefixes.
	// Such tags are recorded with the unknown prefix as the name space URL.
	Strict bool

	// When Strict == false, AutoClose indicates a set of elements to
	// consider closed immediately after they are opened, regardless
	// of whether an end element is present.
	AutoClose []string

	// Entity can be used to map non-standard entity names to string replacements.
	// The parser behaves as if these standard mappings are present in the map,
	// regardless of the actual map content:
	//
	//	"lt": "<",
	//	"gt": ">",
	//	"amp": "&",
	//	"apos": "'",
	//	"quot": `"`,
	Entity map[string]string

	// CharsetReader, if non-nil, defines a function to generate
	// charset-conversion readers, converting from the provided
	// non-UTF-8 charset into UTF-8. If CharsetReader is nil or
	// returns an error, parsing stops with an error. One of the
	// CharsetReader's result values must be non-nil.
	CharsetReader func(charset string, input io.Reader) (io.Reader, error)

	// DefaultSpace sets the default name space used for unadorned tags,
	// as if the entire XML stream were wrapped in an element containing
	// the attribute xmlns="DefaultSpace".
