RE: finding the last element with attribute

I am trying to output the string value of the option elements that have
a selected="selected" attribute and separate the output with commas. I
don't want a comma after the last string value that I output. If all of
the option elements had a selected="selected" attribute then I would
expect to get: "East Devon, Exeter, Torbay" - which I do. If only the
first two had a selected="selected" attribute then I would expect to get
"East Devon, Exeter" but instead I get "East Devon, Exeter," so I need
to loose that comma at the end. I need a test to find the last option
element that has a selected="selected" attribute.

Thanks
Rob
