html - 在 watir 中搜索带下划线的链接

Question

我正在尝试搜索/选择页面中带下划线的链接，而其他页面则没有。来源是这样的:

<a href="someurl1">
<b>
<u>Some ulined text</u>
</b>
<u></u>
</a>
<br>
<a href="someurl2">Other link text</a>
<br>
<a href="someurl3">Another Link text</a>
<br>

我试过类似的东西

link = browser.link(:u?, true)
link.exists?

我得到以下错误

TypeError: expected one of [String, Regexp], got true:TrueClass

    from /usr/lib/ruby/gems/1.8/gems/watir-webdriver-0.2.4/lib/watir-webdriver/elements/element.rb:31:in `exist?'

编辑:所以我实际上是用它来抓取屏幕而不是测试。这或许可以解释为什么 watir 不直接支持这一点的原因，因为 CSS 和其他更好的实践对测试有意义，而且当您将 HTML 开发和测试齐头并进时。 Hoserver 从抓取的角度来看，文本格式是用户看到的，搜索带下划线、粗体的链接等对抓取有意义。

我以前从未见过在测试用例中使用过那种属性。我也没有看到任何代码支持它。你可能需要自己动手。这是一个例子 borrowed from Zeljko

def hasUnderlined(browser)
  s = false
  browser.links.each do |l| 
    if l.html.downcase.match /\<u\>*\<\/u\>/
      s = true
    end
  end
end

def getUnderlined(browser)
  browser.links.each do |l| 
    if l.html.downcase.match /\<u\>*\<\/u\>/
      return l
    end
  end
end
