Function Name Description

current The currentmethod returns a node set that contains the current

node as its only member

available in the function library

Datetime

The datetime family of methods returns information that is date- and time-related

Error/Trace

The error/trace family provides information regarding errors that are returned

error(error) error(error, description) error(error, description, error-object)

trace(value, label) This is used to debug queries

Node

The node family of functions returns information that is primarily information about the specified node

name() The name()method returns the name of the current node or the name(nodeset) first node in the node set passed to the method

local-name() The local-name()method returns the name of the current node or local-name(nodeset) the first node in the specified node set without the namespace prefix namespace-uri() The namespace-uri()method returns the namespace URI of the namespace-uri(nodeset) current node or the first node of the specified node set that is

passed to the method

lang(lang) The lang()method returns a boolean if the language of the

cur-rent node matches the specified language

root() The root()returns the root of the tree to which the specified node root(node) belongs to If no node is specified, the current node is used The

return value will typically be a document node
