我正在尝试使用部分 href xpath 扫描 HTML 表中的行,并使用该行的其他列值执行进一步测试。

  <div id = "blah">
  <table>
    <tr>
      <td><a href="afile?key=HONDA">link</a></td>
      <td>29 33 485</td>
      <td>45.2934,00 EUR</td>
    </tr>
    <tr>
      <td><a href="afile?key=HONDA">link</a></td>
      <td>22 93 485</td>
      <td>38.336.934,123 EUR</td>
    </tr>
    <tr>
      <td><a href="afile?key=something_else">link</a></td>
      <td>394 27 3844</td>
      <td>3.485,2839 EUR</td>
    </tr>    
  </table>
  </div>

在 cucumber-jvm 步骤定义中,我很容易执行此操作,如下所示(我更喜欢使用 Ruby)

@Given("^if there are...$")
public void if_there_are...() throws Throwable {
            ...
            ...
           baseTable = driver.findElement(By.id("blah"));
           tblRows = baseTable.findElements(By.tagName("tr"));

        for(WebElement row : tblRows) {                                                 
            if (row.findElements(By.xpath(".//a[contains(@href,'key=HONDA')]")).size() > 0) {
                List<WebElement> col = row.findElements(By.tagName("td")); 
                tblData dummyThing = new tblData();
                dummyThing.col1 = col.get(0).getText();
                dummyThing.col2 = col.get(1).getText();
                dummyThing.col3 = col.get(2).getText();
                dummyThing.col4 = col.get(3).getText();
                dummyThings.add(dummyThing);
            }
        }

我在这里一无所知

page.find('#blah').all('tr').each { |row|
  # if row matches xpath then grab that complete row
  # so that other column values can be verified
  # I am clueless from here
  row.find('td').each do { |c|

  }
  page.find('#blah').all('tr').find(:xpath, ".//a[contains(@href,'key=HONDA')]").each { |r|
    #we got the row that matches xpath, let us do something
  }
}

我认为你正在寻找:

page.all('#blah tr').each do |tr|
  next unless tr.has_selector?('a[href*="HONDA"]')

  # Do stuff with trs that meet the href requirement
  puts tr.text
end
#=> link 29 33 485 45.2934,00 EUR
#=> link 22 93 485 38.336.934,123 EUR

这基本上是说:

  1. 在 id 为 'blah' 的元素中查找所有 trs
  2. 遍历每个 trs
  3. 如果 tr 没有包含 HONDA 的 href 的链接,请忽略它
  4. 否则,输出行的文本(匹配条件)。你可以用这里的 tr 做任何你需要的事情。

您还可以使用 xpath 将上述内容折叠成一条语句。但是,我不认为它具有可读性:

page.all(:xpath, '//div[@id="blah"]//tr[.//a[contains(@href, "HONDA")]]').each do |tr|
  # Do stuff with trs that meet the href requirement
  puts tr.text
end
#=> link 29 33 485 45.2934,00 EUR
#=> link 22 93 485 38.336.934,123 EUR

以下是如何检查每个匹配行的链接 url 和列值的示例:

page.all('#blah tr').each do |tr|
  next unless tr.has_selector?('a[href*="HONDA"]')

  # Do stuff with trs that meet the href requirement
  href = tr.find('a')['href']
  column_value_1 = tr.all('td')[1].text
  column_value_2 = tr.all('td')[2].text

  puts href, column_value_1, column_value_2
end
#=> file:///C:/Scripts/Misc/Programming/Capybara/afile?key=HONDA
#=> 29 33 485
#=> 45.2934,00 EUR
#=> file:///C:/Scripts/Misc/Programming/Capybara/afile?key=HONDA
#=> 22 93 485
#=> 38.336.934,123 EUR
