通过Xpath获取值

Question

我试图通过Xpath从我的html中检索一个值。就其价值而言，这是一个CRM web工具(微软的)，它看起来像是一个iFrame，它根据在其条上选择的链接(客户、上诉等)进行更改。

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

		</tr></tbody>

​

我在用：

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

但结果是0。意味着找不到任何东西。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，没有发现任何势利物(计数为0)。基本上，我希望从我的html中获得以下值中的一个(或全部)：A1、A1.2、A5、A6、A9。

Answer 1

为第一个元素(A1)尝试以下XPATH：

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

或

如果您已经知道文本，即A1 (静态内容)

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

对于A2

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

或

如果您已经知道文本，即A2 (静态内容)

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

请共享table HTML代码，以便我们可以使XPATH更加特定于。

Answer 2

试试下面的xpath。

获取A1的值

解释：这里您的元素在table中。因此，使用tr标记启动xpath，然后继续使用td标记和nobr标记。使用class属性的nobr标记，并继续使用a标记和text方法。

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

获取3的值

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

获取9的值

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