java - Selenium WebDriver 在选择 xpath 时抛出错误

Question

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

我的HTML是这样的

<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

看起来你的引号搞砸了。在 XPath 中使用单引号可以避免此类问题。

// 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，请仔细阅读错误，它已经告诉了你足够的信息。如您所见，消息中的选择器中没有引号。

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