Functions

func NewExprLex

func NewExprLex(
	expr string,
	progBldr *xpath.ProgBuilder,
	mapFn xpath.PfxMapFn,
) *exprLex

func NewExprMachine

func NewExprMachine(
	expr string,
	mapFn xpath.PfxMapFn,
) (*xpath.Machine, error)

Create a machine that can run the full XPATH grammar for 'when' and 'must' statements. 'expr' matches the name given to this full grammar (as in Expr / ExprToken in the XPATH RFC)

func NewExprMachineWithCustomFunctions

func NewExprMachineWithCustomFunctions(
	expr string,
	mapFn xpath.PfxMapFn,
) (*xpath.Machine, error)
