xsl:on-completion

Occurs within xsl:iterate to define processing to be carried out when the input sequence is exhausted.

Content: sequence-constructor
Permitted parent elements: xsl:iterate

Attributes

select?

expression

The effect of the instruction may be defined either by an expression within the optional select attribute, or by the enclosed sequence constructor.

Saxon availability

Available in XSLT 3.0. From Saxon 9.8, available in all editions. Implemented in Saxon-PE and Saxon-EE since Saxon 9.6. Available for all platforms.

Notes on the Saxon implementation

The rule that xsl:on-completion executes with no context item was first implemented in Saxon 9.8.

In earlier working drafts of XSLT 3.0, the xsl:on-completion element came last in the body of the xsl:iterate instruction. This caused problems with the scope of local variables, so in the final Recommendation, xsl:on-completion comes first. The new rule was implemented in Saxon 9.7. The spec has also changed to clarify that xsl:on-completion is evaluated if the input sequence to xsl:iterate is empty.

Details

During execution of xsl:on-completion there is no context item, position or size; the instruction has access to the iteration parameters with the values given on the last iteration (or the initial values of the xsl:param elements if the input sequence was empty). For further details see xsl:iterate.
