硒的webdriver拋出錯誤，而選擇的XPath

Question

driver.findElement(By.xpath("//input[@type="+"checkbox"+"]/following-sibling:://td[contains(text(),"+"template"+"]")) 

我的HTML是這樣

<tr> 
<td class="tablecontent"> 
<input type="checkbox" value="59781" name="templateIds"> 
</td>`enter code here` 
<td class="tablecontent"> test11 </td> 
</tr> 

org.openqa.selenium.InvalidSelectorException: The given selector //input[@type=checkbox]/following-sibling:://td[contains(text(),template] is either invalid or does not result in a WebElement. The following error occurred: InvalidSelectorError: Unable to locate an element with the xpath expression //input[@type=checkbox]/following-sibling:://td[contains(text(),template] because of the following error: [Exception...

Answer 1

看起來你搞砸了引號。在XPath中使用單引號來避免這樣的問題。

// if template is the text within your XPath 
driver.findElement(By.xpath("//input[@type='checkbox']/following-sibling:://td[contains(text(), 'template']")); 

// if template is your variable, then it should be 
driver.findElement(By.xpath("//input[@type='checkbox']/following-sibling:://td[contains(text(), " + template + "']")); 

另外，請仔細閱讀錯誤，它會告訴您足夠的信息，您已經足夠了。正如你所看到的，消息中的選擇器中沒有引號。

The given selector //input[@type=checkbox]/following-sibling:://td[contains(text(),template] is either invalid or does not result in a WebElement.

Answer 2

"//input[@type="+"checkbox"+"]/following-sibling:://td[contains(text(),"+"template"+"]" 

產生錯誤的字符串。從蟒蛇嘗試：

"//input[@type="+"checkbox"+"]/following-sibling:://td[contains(text(),"+"template"+"]" 
'//input[@type=checkbox]/following-sibling:://td[contains(text(),template]' 

您應環繞複選框，模板，報價得到

"//input[@type="checkbox"]/following-sibling:://td[contains(text(),"template"]" 

或

"//input[@type='checkbox']/following-sibling:://td[contains(text(),'template']" 

使用

"//input[@type="+"'checkbox'"+"]/following-sibling:://td[contains(text(),"+"'template'"+"]" 

或

"//input[@type='{type}']/following-sibling:://td[contains(text(),'{text}']".format(type='checkbox',text='template') 

Answer 3

您的「包含」功能沒有右括號 並且需要正確的引用。

如果複選框和模板都是字符串，試試這個：

driver.findElement(By.xpath("//input[@type='checkbox']/following-sibling:://td[contains(text(),'template')]")) 

，如果他們是變量，試試這個：

driver.findElement(By.xpath("//input[@type='" +checkbox+"']/following-sibling:://td[contains(text(),'"+template+"')]"))
