通过Xpath获取值

我试图通过Xpath从我的html中检索出一个值。对于它的价值，这是一个CRM的网络工具（微软的），它看起来像一个DINAMIC的iFrame根据其栏上选择的链接，改变（客户，上诉等）通过Xpath获取值

<tbody><tr class="ms-crm-List-Row" oid="{665A4B9C-9658-E611-922C-441EA1745BC2}" otype="10046" otypename="new_contact_content">

\t \t </tr></tbody>

我使用：

var nobrValues = _webdriverIE.FindElements(By.XPath("//nobr[@class='gridcellpadding']"));

但结果是0含义没有找到对象。我也试过：

var _tableOfInterestsCount = _webdriverIE.FindElements(By.XPath("//table[@id='gridBodyTable']/tbody/tr[1]/td")); 
     var nobrvalues = var nobrValues = _tableOfInterestsCount.FindElements(By.XPath("//nobr[@class='gridcellpadding']"));

但是也没有NOBR的发现（计数为0）。基本上，我想从我的html中获得下列值中的一个（或全部）：A1，A1.2，A5，A6，A9。

在HTML表

尝试为第1元以下XPath（A1）：

var nobrValues = _webdriverIE.FindElement(By.XPath("//tbody/tr[1]/td[2]/nobr/a"));

或者

如果你已经知道文即A1（静态内容）

var nobrValues = _webdriverIE.FindElement(By.XPath("//nobr/a[text()='A1']"));

为A2：

var nobrValues = _webdriverIE.FindElement(By.XPath("//tbody/tr[2]/td[2]/nobr/a"));

或者

如果你已经知道文即A2 （静态内容）

var nobrValues = _webdriverIE.FindElement(By.XPath("//nobr/a[text()='A2']"));

请分享table的HTML代码，这样我们就可以让XPATH 具体更多。

感谢详细的解答的价值。您的选项都不成功。我收到了非静态内容的选项的例外情况。我感觉我不在正确的页面上。另一方面，我可以认识到有2个tr（意思是两行），但不能获取它的值。顺便说一句，这是一个CRM（微软的网络工具）。 –

你可以发布异常跟踪吗？另外，检查表格是否在框架内。如果是的话，你可以在这里看看我的答案以获取更多与切换黑白相框有关的详细信息http://stackoverflow.com/a/40759300/2575259 –

请尝试下面的xpath。

至获取A1的价值

说明：这里你的元素是table内。因此，请使用tr标记开始xpath，然后继续使用td标记和nobr标记。使用nobr标签的class属性，并使用text方法继续使用a标签。

//tr/td/nobr[@class='gridcellpadding']/a[contains(text(), 'A1')]

拿到

//tr/td/nobr[@class='gridcellpadding']/a[contains(text(), '3')]

值来获得

//tr/td/nobr[@class='gridcellpadding']/a[contains(text(), '9')]
