Types

type Ctxt

type Ctxt struct {
	// contains filtered or unexported fields
}

Ctxt represents the Parser context. You normally should be using Parser, but if you for some reason need to do more low-level magic you will have to tinker with this struct

func NewCtxt

func NewCtxt(s string, o Option) (*Ctxt, error)

NewCtxt creates a new Parser context

func (*Ctxt) Free

func (ctx *Ctxt) Free() error

Free releases the underlying C struct

func (Ctxt) Parse

func (ctx Ctxt) Parse() error

Parse starts the parsing on the Ctxt

func (Ctxt) Pointer

func (ctx Ctxt) Pointer() uintptr

Pointer returns the underlying C struct

type HTMLOption

type HTMLOption int

HTMLOption represents the HTML parser options that can be used when parsing HTML

type Option

type Option int

Option represents the parser option bit

const (
	XMLParseRecover    Option = 1 << iota /* recover on errors */
	XMLParseNoEnt                         /* substitute entities */

	XMLParseCompact                       /* compact small text nodes; no modification of the tree allowed afterwards (will possibly crash if you try to modify the tree) */

	XMLParseHuge                          /* relax any hardcoded limit from the parser */
	XMLParseOldSAX                        /* parse using SAX2 interface before 2.7.0 */
	XMLParseIgnoreEnc                     /* ignore internal document encoding hint */

	XMLParseMax
	XMLParseEmptyOption Option = 0
)
