点击xpath和黄瓜表中的编辑链接

Question

如何使用黄瓜单击xpath中表格中的项目列表中的编辑链接？

我有一个选择器工作，返回我需要的链接，但它是许多结果之一....我怎么能只返回1结果？

这是我的黄瓜步

When /^I click the "([^\"]*)" link for "([^\"]*)"$/ do |link, cell_value| 
    within "//*[.//td[contains(.,'#{cell_value}')] and .//a[text()='#{link}']]" do |scope| 
    scope.click_link link 
    end 
end 

正如你可以看到这会工作，但只需点击表格中的第一个编辑链接，即使它知道，它已经匹配了别人......所以那不好。
