Syntax
previous element-qualifier* (is | isnt) (element-name | element-name-list)
A test that succeeds if the qualified element is not the first subelement of its parent, and if the previous subelement has the specified element name. Otherwise, it fails (and returns false).
For example, the following "do...done" block uses a previous is test, and the actions within the block (not shown here) will only be executed if the current element follows a paragraph (par) element:
do when previous is par ... done
The previous is test ignores inclusions and data content.
