Node-set Functions

number last()

Returns the number of nodes in the context node list. This is the same as the position of the last node in the list.

number position()

Returns the position of the context node in the context node list. The first node has position 1, not 0.

number count(node-set)

Returns the number of nodes in the argument

node-set id(object)

Returns a node-set containing the single element node with the specified id as determined by an ID-type attribute. If no node has the specified ID, then this function returns an empty node-set. If the argument is a node-set, then it returns a node-set containing all the element nodes whose ID matches the string-value of any of the nodes in the argument node-set.

string local-name(node-set?)

Returns the local name of the first node in the argument node-set, or the local name of the context node if the argument is omitted. It returns an empty string if the relevant node does not have a local name (i.e. it’s a comment, root, or text node.)

string namespace-uri(node-set?)

Returns the namespace name of the first node in the argument node-set, or the namespace name of the context node if the argument is omitted. It returns an empty string if the node is an element or attribute that is not in a namespace. It also returns an empty string if namespace names don’t apply to this node (i.e. it’s a comment, processing instruction, root, or text node.)

string name(node-set?)

Returns the full, prefixed name of the first node in the argument node-set, or the name of the context node if the argument is omitted. It returns the empty string if the relevant node does not have a name (e.g. it’s a comment or text node.)
