Types

type Parser

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

Parser implements LL(1) recursive descent parsing for XML. It maintains a single token lookahead for predictive parsing.

func NewParser

func NewParser(input string) *Parser

NewParser creates a new XML parser for the given input string. For parsing from io.Reader, use NewParserFromStream instead.

func NewParserFromStream

func NewParserFromStream(stream shapetokenizer.Stream) *Parser

NewParserFromStream creates a new XML parser using a pre-configured stream. This allows parsing from io.Reader using tokenizer.NewStreamFromReader.

func (*Parser) Parse

func (p *Parser) Parse() (ast.SchemaNode, error)

Parse parses the input and returns an AST representing the XML document.

Grammar:

Document = [ XMLDecl ] Element

Returns ast.SchemaNode - the root of the AST. For XML data, this will be an ObjectNode representing the root element.
