通過Xpath獲取值

我試圖通過Xpath從我的html中檢索出一個值。對於它的價值，這是一個CRM的網絡工具（微軟的），它看起來像一個DINAMIC的iFrame根據其欄上選擇的鏈接，改變（客戶，上訴等）通過Xpath獲取值

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

我使用：

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

但結果是0含義沒有找到對象。我也試過：

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

但是也沒有NOBR的發現（計數爲0）。基本上，我想從我的html中獲得下列值中的一個（或全部）：A1，A1.2，A5，A6，A9。

在HTML表

嘗試爲第1元以下XPath（A1）：

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

或者

如果你已經知道文即A1（靜態內容）

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

爲A2：

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

或者

如果你已經知道文即A2 （靜態內容）

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

請分享table的HTML代碼，這樣我們就可以讓XPATH 具體更多。

感謝詳細的解答的價值。您的選項都不成功。我收到了非靜態內容的選項的例外情況。我感覺我不在正確的頁面上。另一方面，我可以認識到有2個tr（意思是兩行），但不能獲取它的值。順便說一句，這是一個CRM（微軟的網絡工具）。 –

你可以發佈異常跟蹤嗎？另外，檢查表格是否在框架內。如果是的話，你可以在這裏看看我的答案以獲取更多與切換黑白相框有關的詳細信息http://stackoverflow.com/a/40759300/2575259 –

請嘗試下面的xpath。

至獲取A1的價值

說明：這裏你的元素是table內。因此，請使用tr標記開始xpath，然後繼續使用td標記和nobr標記。使用nobr標籤的class屬性，並使用text方法繼續使用a標籤。

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

拿到

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

值來獲得

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