last()

Returns the number of nodes matching the axis.

chapter/verse[last()] The last verse in each chapter.

ancestor::node()[last()] The furthest ancestor from the current node.

count(node-set)

Returns the number of nodes matching the node-set pattern.

local-part(node)

Returns the local part of the node's name. In other words, the node name stripped of the namespace prefix.

namespace(node)

Returns the namespace URL the node's name.

name(node)

Returns the node's name.

id(idref)

Returns the node with the 'ID' attribute equals to idref. The ID attribute is assigned in the DTD. The actual attribute name may, of course, vary.

string(obj)

Converts the object to a string.

concat(s1, s2, ...)

Concatenates strings.

starts-with(string, head)

True if string starts with head.

contains(string, substring)

True if string contains substring.

substring-before(string, substring)

Returns the substring of string before matching substring.

substring-after(string, substring)

Returns the substring of string after the matching substring.

string-length(string)

Returns the string length of string.

normalize-space(string)

Normalizes whitespace. Consecutive whitespace is converted into a single space. Leading and trailing whitespace is trimmed.

translate(string, from, to)

Converts characters in a string, like the 'tr' command.

boolean(obj)

Converts obj into a boolean.

true()

Returns true.

false()

Returns false.

lang(language)

Returns true if the context node has an xml:lang of language.

number(obj)

Converts obj to a number (Java double).

sum(node-set)

Converts the node values of node-set to numbers and adds them.

floor(number)

Returns the closest integer below number.

ceiling(number)

Returns the closest integer above number.

round(number)

Rounds number to the nearest integer.

if(test,a,b)

Conditionally selects the value of a or b. If test evaluates to true, return the value of a. Otherwise, return the value of b.
