Syntax

previous element-qualifier* (is | isnt) (element-name | element-name-list)
    

A test that succeeds if the previous sibling element has the specified element name. Otherwise, it fails (and returns false). It also fails if the qualified element is not the first subelement of its parent. Replacing is with isnt will reverse the results.

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.
