Syntax
last proper? content element-qualifier (is | isnt) (#DATA | element-name | content-identifier-list)
An element test that returns "true" in two cases:
#data
was specified.
The test returns "false" otherwise. Replacing is
with isnt
will reverse these results.
When the keyword proper
is specified, the last content is
test ignores included elements. If all the subelements of the referenced element have been included elements, and if there was no data content in the element, the test fails.
Note that at the start of an element
rule, there is no last content
of that element, so any test for it will fail.
The test last content is #data
is true in a data-content
rule only if the data content is immediately preceded by either an external data entity reference or one or more processing instructions, which are in turn preceded either by data content or by an external data entity reference. It never applies to the content processed by the data-content
rule.
The following is an example of a data-content
rule that uses the last content is
test:
data-content output "%c" output " (again) " when last content is #data
