Xslt1

Iterates over a node-set or sequence, applying the contained template body to each item in document order.

Conditionally outputs content when a boolean XPath expression evaluates to true; has no else branch.

Imports another stylesheet at a lower import precedence, allowing the importing stylesheet to override any of its declarations.

Merges another stylesheet's top-level declarations into the current stylesheet at the same import precedence.

Default fallback branch inside xsl:choose, instantiated when no xsl:when condition evaluates to true.

Controls how the result tree is serialised — output method, encoding, indentation, DOCTYPE, and other serialisation options.

Declares a parameter with an optional default value, accepting values passed via xsl:with-param or from the calling environment.

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.

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