XSLT Instructions

Reference for the XSLT instructions implemented by goxslt. Each instruction has its own page with attributes, a minimal example, and additional examples where helpful.

Templates

• xsl:template — define a match or named template
• xsl:apply-templates — select nodes and apply matching templates
• xsl:call-template — invoke a named template
• xsl:next-match — chain to the next matching template
• xsl:apply-imports — apply imported template rules
• xsl:with-param — pass a parameter to a template or function

Control flow

• xsl:if — conditional execution
• xsl:choose — multi-branch conditional (with xsl:when / xsl:otherwise)
• xsl:for-each — iterate over a sequence
• xsl:for-each-group — group and iterate
• xsl:iterate — loop with accumulating parameters (with xsl:break, xsl:next-iteration, xsl:on-completion)
• xsl:try — catch dynamic errors (with xsl:catch)

Variables and parameters

• xsl:variable — bind a variable
• xsl:param — declare a parameter

Result tree construction

• xsl:value-of — write a string value
• xsl:text — write literal text
• xsl:sequence — add items to the result
• xsl:copy — shallow copy of the current node
• xsl:copy-of — deep copy
• xsl:element — create an element with computed name
• xsl:attribute — create an attribute
• xsl:comment — create a comment node
• xsl:processing-instruction — create a processing instruction
• xsl:namespace — create a namespace node

Sorting and grouping

• xsl:sort — sort criterion for for-each / apply-templates / perform-sort
• xsl:perform-sort — sort a sequence

Strings and numbers

• xsl:analyze-string — split a string by a regular expression
• xsl:number — generate formatted numbers

Output

• xsl:result-document — write to a secondary output

Maps

• xsl:map — construct an XPath map (with xsl:map-entry)

Stylesheet structure

• xsl:function — define a custom XPath function
• xsl:key — declare an index for key() lookup
• xsl:package — package as root element
• xsl:message — emit a diagnostic message
• xsl:fallback — fallback for unknown instructions
