Inside XSLT

The XSLT Functions

The following list includes, in overview, the functions built into XSLT:

• current(). Returns the current node—not the context node. The current node is the present node in loops such as <xsl:for-each>. You cannot use current in patterns.

• document(). Enables you to read in multiple documents.

• element-available(). Indicates whether an extension element is available.

• format-number(). Formats numbers for display.

• function-available(). Indicates whether an extension function is available.

• generate-id(). Causes the XSLT processor to assign and return an identifier to a node. When you call generate-id again on the same node, this function returns the previously assigned identifier.

• key(). Enables you to search by key.

• system-property()
