XSLT functions

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

XSLT functions

XSLT contains over 100 built-in functions. These functions for string values, numeric, date and time comparison, node and QName manipulation, sequence manipulation, Boolean values, and so on.

Note The default function namespace prefix is ​​fn.

Note Function namespace URI is:

Tip: function to be called from time to time with the fn: prefix, such as fn: string ().However, since fn: it is the default namespace prefix, then when it is called, does not have to use the prefix name of the function.

You can access all the built-in XSLT 2.0 Functions reference manual in our XPath tutorial.
