I had a look at the example page you gave. Both the HTML and Javascript are buggy. The HTML::TreeBuilder::XPath I mentioned won't be of any use in this situation. I was able to get to the city element with '//span[@id="city"]'. The id attributes are supposed to be unique so I'd recommend targetting them directly - that should hopefully get around issues with malformed markup. And it looks like I'm now starting to repeat what Corion already has below, so I'll shut up now. :-)
