First, there is no need to use YQL, I recommend the more straight forward XPath Fetch page module here. That being said, both work, so no need to worry about it.
The problem you evoked isn't one: the module does fetch what you asked, it's just HTML and not an rss feed. First thing to do would be to slightly modify your XPath expression by adding /tbody/* at the end, eg get xpath='//table[@id="searchResultsTable"]/tbody/*'. That way you get only the results instead of the whole table. Next is to rename the fields, using the Rename module, to get only data relevant to you. Finally, maybe a regex module to get rid of extraneous data.
