Functions

func Marshal 

func Marshal(a tree.Adapter, n interface{}, w io.Writer) error

Marshal prints the result tree, r, in XML form to w.

func MarshalStr 

func MarshalStr(a tree.Adapter, n interface{}) (string, error)

MarshalStr is like Marhal, but returns a string.

func ParseExec 

func ParseExec(xpstr string, a tree.Adapter, t interface{}, opts ...FuncOpts) (tree.Result, error)

ParseExec parses the XPath string, xpstr, and runs Exec.

Types

type FuncOpts 

type FuncOpts func(*Opts)

FuncOpts is a function wrapper for Opts.

type Opts 

type Opts struct {
	NS    map[string]string
	Funcs map[xml.Name]tree.Wrap
	Vars  map[string]tree.Result
}

Opts defines namespace mappings and custom functions for XPath expressions.

type XPathExec 

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

XPathExec is the XPath executor, compiled from an XPath string

func MustParse 

func MustParse(xp string) XPathExec

MustParse is like Parse, but panics instead of returning an error.

func Parse 

func Parse(xp string) (XPathExec, error)

Parse parses the XPath expression, xp, returning an XPath executor.

func (XPathExec) Exec 

func (xp XPathExec) Exec(a tree.Adapter, t interface{}, opts ...FuncOpts) (tree.Result, error)

Exec executes the XPath expression, xp, against the tree, t, with the namespace mappings, ns, and returns the result as a stringer. The adapter 'a' is used to adapt the underlying XML representation to xpath needs.

func (XPathExec) ExecBool 

func (xp XPathExec) ExecBool(a tree.Adapter, t interface{}, opts ...FuncOpts) (bool, error)

ExecBool is like Exec, except it will attempt to convert the result to its boolean value.

func (XPathExec) ExecNode 

func (xp XPathExec) ExecNode(a tree.Adapter, t interface{}, opts ...FuncOpts) (tree.NodeSet, error)

ExecNode is like Exec, except it will attempt to return the result as a node-set.

func (XPathExec) ExecNum 

func (xp XPathExec) ExecNum(a tree.Adapter, t interface{}, opts ...FuncOpts) (float64, error)

ExecNum is like Exec, except it will attempt to convert the result to its number value.

func (XPathExec) MustExec 

func (xp XPathExec) MustExec(a tree.Adapter, t interface{}, opts ...FuncOpts) tree.Result

MustExec is like Exec, but panics instead of returning an error.
