Reference

Exits an xsl:iterate loop early and returns an optional final value, enabling efficient early-termination patterns over large sequences.

Invokes a named template by name, optionally passing parameters, without changing the current context node.

Handles dynamic errors thrown inside an xsl:try block, with access to error code, description, and value for precise recovery logic.

Declares a named mapping of individual characters to output strings, applied during serialization to replace characters in the result.

Multi-branch conditional that evaluates xsl:when conditions in order and optionally falls back to xsl:otherwise.

Generates an XML comment node in the result tree with content computed from the element body.

Creates a shallow copy of the current node — the node itself but not its children or attributes — into the result tree.

Performs a deep copy of a node-set or value into the result tree, preserving all descendants, attributes, and namespaces.

Creates an element node in the result tree with a name computed at runtime from an XPath expression.

Provides fallback content to execute when an enclosing extension element or unrecognised instruction is not supported by the processor.
