xsl:on-completion¶
Occurs within xsl:iterate
to define processing to be carried out when the input sequence is exhausted.
Available in XSLT 3.0. From Saxon 9.8, available in all editions. Implemented in Saxon-PE and Saxon-EE since Saxon 9.6.
- 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.
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
