问题

以下是您要的翻译部分：

以下是我要点击的按钮的检查代码，以确认我的订单

我确认我的订单

我确认我的订单
```

我尝试过的代码：

driver.findElement(By.xpath("//button[contains(text(),'我确认我的订单')]")).click();

在使用Eclipse作为Selenium测试的IDE时，出现了以下错误：

org.openqa.selenium.InvalidSelectorException: 无效的选择器：无法定位具有XPath表达式//button[contains(text(),'我确认我的订单')]的元素，原因如下：
SyntaxError: 未能在Document上执行'evaluate'：字符串'//button[contains(text(),'我确认我的订单')]'不是有效的XPath表达式。

The following inspect code i have is to click the button  I can confirm my order

<button type="submit" class="button btn btn-default button-medium">
<span>I confirm my order<i class="icon-chevron-right right"></i></span>
</button>
<span>I confirm my order<i class="icon-chevron-right right"></i></span>

The one I've tried:

```
driver.findElement(By.xpath("//button[contains(text(),'I confirm my order')]\"")).click();
```

The error is coming out using Eclipse as IDE for Selenium Testing stated below:

    org.openqa.selenium.InvalidSelectorException: invalid selector: Unable to locate an element with the xpath expression //button[contains(text(),'I confirm my order')]" because of the following error:
    SyntaxError: Failed to execute 'evaluate' on 'Document': The string '//button[contains(text(),'I confirm my order')]"' is not a valid XPath expression.

Try this:

    driver.find_element_by_xpath(&#39;//button[@type=&quot;submit&quot;]/span[1]&#39;).click()

以下是翻译好的部分：

**我确认我的订单** 文本位于 `&lt;button&gt;` 元素的子元素 `&lt;span&gt;` 中。因此，要对该元素执行 `click()` 操作，您可以使用以下任一[定位策略](https://stackoverflow.com/questions/48369043/official-locator-strategies-for-the-webdriver/48376890#48376890)：

- `cssSelector`：

	  driver.findElement(By.cssSelector("button.button.btn.btn-default.button-medium > span i.icon-chevron-right.right")).click();

- `xpath`：

	  driver.findElement(By.xpath("//button[@class='button btn btn-default button-medium'][./span[contains(., '我确认我的订单')]]")).click();

然而，由于该元素是一个启用了[JavaScript](https://www.javascript.com/)的元素，因此要对其执行 `click()` 操作，您需要使用[WebDriverWait](https://stackoverflow.com/questions/48989049/selenium-how-selenium-identifies-elements-visible-or-not-is-is-possible-that-i/48990165#48990165)来等待 `elementToBeClickable()`，您可以使用以下任一[定位策略](https://stackoverflow.com/questions/48369043/official-locator-strategies-for-the-webdriver/48376890#48376890)：

- `cssSelector`：

	  new WebDriverWait(driver, 20).until(ExpectedConditions.elementToBeClickable(By.cssSelector("button.button.btn.btn-default.button-medium > span i.icon-chevron-right.right"))).click();

- `xpath`：

	  new WebDriverWait(driver, 20).until(ExpectedConditions.elementToBeClickable(By.xpath("//button[@class='button btn btn-default button-medium'][./span[contains(., '我确认我的订单')]]"))).click();

The text **I confirm my order** is within the child `&lt;span&gt;` of the `&lt;button&gt;` element. So, to `click()` on the element you can use either of the following [Locator Strategies](https://stackoverflow.com/questions/48369043/official-locator-strategies-for-the-webdriver/48376890#48376890):

- `cssSelector`:

	  driver.findElement(By.cssSelector(&quot;button.button.btn.btn-default.button-medium &gt; span i.icon-chevron-right.right&quot;)).click();
           	
- `xpath`:

	  driver.findElement(By.xpath(&quot;//button[@class=&#39;button btn btn-default button-medium&#39;][./span[contains(., &#39;I confirm my order&#39;)]]&quot;)).click();

However, as the element is a [JavaScript](https://www.javascript.com/) enabled element so to `click()` on the element you need to induce [WebDriverWait](https://stackoverflow.com/questions/48989049/selenium-how-selenium-identifies-elements-visible-or-not-is-is-possible-that-i/48990165#48990165) for the `elementToBeClickable()` and you can use either of the following [Locator Strategies](https://stackoverflow.com/questions/48369043/official-locator-strategies-for-the-webdriver/48376890#48376890):

- `cssSelector`:

	  new WebDriverWait(driver, 20).until(ExpectedConditions.elementToBeClickable(By.cssSelector(&quot;button.button.btn.btn-default.button-medium &gt; span i.icon-chevron-right.right&quot;))).click();
           	
- `xpath`:

	  new WebDriverWait(driver, 20).until(ExpectedConditions.elementToBeClickable(By.xpath(&quot;//button[@class=&#39;button btn btn-default button-medium&#39;][./span[contains(., &#39;I confirm my order&#39;)]]&quot;))).click();
