Clip to Add class=”wrap” to last TD tag in each TR tag

This is written in response to a request from Don Strack on the notetab clips list. His problem is that he wants to have a special class on the last TD tag in each set of TR tags in an existing page. He apparently adds new sets periodically, so he may already have some of them with a class attribute in them.

This clips has the following highlights:

  • it finds matching tr and /tr tag sets
  • it looks backwards through the tr tag to find the last td tag
  • it determines if there is already a class attribute in that td tag … and if yes, move on, if not, it adds it
  • then it steps to the next tr/tr tag set.
