Using XSLT Functions in XPath Expressions
The XPath specification defines many functions. XSLT style sheets have several additional functions available to them. These include:
| Function | Description |
|---|---|
| document(obj, ns?) | Allows processing of more than one source document |
| key(str, obj) | Retrieves a key assigned by the <xsl:key> element |
| format-number(num, str, str?) | Formats a numeric value in any of a variety of ways |
| current() | Locates the current node in a node-set |
| unparsed-entity-uri(str) | Returns the URI of a specified unparsed entity |
| generate-id(ns?) | Assigns a unique identifier to the first node in a given node-set |
| system-property(str) | Returns the value of a specified system property, such as the name or version of the XSLT processor |
For more information about these functions, including examples, see the following topics in the XSLT Reference:
