XSLT Functions

XQuery 1.0, XPath 2.0, and XSLT 2.0 share the same functions library.

XSLT Functions

XSLT includes over 100 built-in functions. There are functions for string values, numeric values, date and time comparison, node and QName manipulation, sequence manipulation, Boolean values, and more.

The URI of the XSLT function namespace is:
http://www.w3.org/2005/02/xpath-functions

The default prefix for the function namespace is fn:.

Tip: Functions are often called with the fn: prefix, such as fn:string(). However, since fn: is the default prefix of the namespace, the function names do not need to be prefixed when called.

The reference of all the built-in XSLT 2.0 functions is located in our XPath tutorial.

In addition, there are the following built-in XSLT functions:

Name	Description
current()	Returns the current node
document()	Used to access the nodes in an external XML document
element-available()	Tests whether the element specified is supported by the XSLT processor
format-number()	Converts a number into a string
function-available()	Tests whether the function specified is supported by the XSLT processor
generate-id()	Returns a string value that uniquely identifies a specified node
key()	Returns a node-set using the index specified by an <xsl:key> element
system-property()	Returns the value of the system properties
unparsed-entity-uri()	Returns the URI of an unparsed entity
