點擊xpath和黃瓜表中的編輯鏈接

Question

如何使用黃瓜單擊xpath中表格中的項目列表中的編輯鏈接？

我有一個選擇器工作，返回我需要的鏈接，但它是許多結果之一....我怎麼能只返回1結果？

這是我的黃瓜步

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 

正如你可以看到這會工作，但只需點擊表格中的第一個編輯鏈接，即使它知道，它已經匹配了別人......所以那不好。

謝謝！
