Reference

Sorts a sequence of items and returns the sorted sequence without iterating over it, enabling sorted results as input to other expressions.

Explicitly preserves whitespace-only text nodes in the named source elements, counteracting xsl:strip-space rules.

Generates an XML processing instruction in the result tree with a computed name and body content.

Writes transformation output to a secondary result document at a specified URI, enabling a single stylesheet to produce multiple output files.

Returns a sequence of items; the XSLT 2.0 equivalent of xsl:value-of for typed values and node sequences.

Specifies a sort key for xsl:apply-templates or xsl:for-each, controlling the order in which nodes are processed.

Processes a source document in streaming mode without loading it fully into memory, enabling transformation of arbitrarily large XML files.

Removes whitespace-only text nodes from the specified source elements before the transformation begins processing them.

Root element of every XSLT stylesheet, declaring the version, namespace, and top-level declarations for the transformation.

Defines a template rule that fires when a node matches a pattern, or a named template that can be called explicitly.
