java - Selenium，如何提取两个 div 标签之间的文本

Question

我刚开始使用 Selenium 在网站上执行 Web 自动化，并且在提取两个 div 标签之间的文本时遇到麻烦。

这是我试图从中提取文本的 HTML 代码片段。

                So I "borrowed" it for a couple days, and now I am going to get one for myself. I am using it with an iPhone, but it would work fine with phones of all sizes, which is nice. If my phone size ever changes the mount will accommodate different sizes phones.

                The phone is very easy to insert and remove , even while driving.

                The mount is easy to position but not loose enough that it doesn't hold the position you want.

其他 div 标签实际上也包含其他文本。

我想从中提取的是: 我给我妻子买了这个支架，她的反馈是它真的很好，即使在开车时也很容易使用。

这是我的代码:

String review;
try {
    review = WebElement.bucketElement.findElement(By.xpath("./td/div")).getText();
} catch (NoSuchElementException nsee) {
    review = "NA";
}

这实际上从所有最里面的 div 标签中提取了所有文本，这不是我想要的。我可以使用 ./td/div/div[3] 定位特定的 div 标签，但无法获取 div 标签之间的文本。

有什么想法吗？

谢谢

您可以使用正则表达式作为解决方法:

String review;
try {
    review = WebElement.bucketElement.findElement(By.xpath("./td/div")).getText();
    review.replaceAll("(<.+>)", "");
} catch (NoSuchElementException nsee) {
    review = "NA";
}

正则表达式删除所有标签和内部元素文本。只剩下第一级文本了。这意味着如果您有:

some strange<div>other text</div> text 结果字符串将为:some strange text

如果需要更复杂的正则表达式here is useful link to test it .
