The UVic events calendar has not presenter field, so that piece of information can't be extracted easily. The dean wants to be able to do exactly that. I wrote Dave W and he said they'll include the request for consideration for the next release of the service, whenever that is.

In the meantime, I've written code that looks for ".." preceding and following zero or more characters in the description field and identifies that as the presenter's name. The code also looks for the first instance of the tag strong class="presenterName" in the description field. I had to use the strong tag because Dave's code strips span tags from the description field.
