Selenium how to select an object by class

Question

I have a web page with a form and has a field that uses the jquery autocomplete function.

This is how the HTML renders after a user name returns 1 or more results.

However I cannot figure out how to make Selenium "click" a result.

Can I do a jQuery type of selector. e.g.

$(".ul.ui-autocomplete li:first a")

Answer 1

Use XPath selector in Selenium:

xpath=//li[contains(@class, 'ui-autocomplete')]/li[1]/a

not checked, might require some corrections.

Answer 2

in response to "Can I do a jQuery type of selector," jQuery uses CSS selectors. Selenium can also use CSS selectors; just prefix the selector with "css=". so:

css=.ul.ui-autocomplete li:first a
