如何在不使用文本的情况下从页面中选择内容？

需要了解如何在不使用文本的情况下选择并单击博客标题，因为内容可能会频繁更改。如何在不使用文本的情况下从页面中选择内容？

我没有“li”标签，所以以前做过的一些事情在这种情况下不起作用。任何帮助将apprecaited。

这里是我试过的最后一件事：

driver.findElement(By.xpath("(//h2[contains(@class, 'blog-post-title')])[3]/a")).click();

您正试图获得与类的第三个元素'博客-后title'但只有两个这样的元素使用XPath定位器尝试。你可以验证你的初始xpath或HTML吗？ – olyv

还有更多元素，但我无法发布更多内容。所以有第三个要素。如果你愿意，可以把这个数字想象成两个。结果是一样的。 – user3493818

好的，这个xpath'// h2 [@ class ='blog-post-title']/a'返回两个href元素。你确实需要其中一个吗？ – olyv

jQuery的可以使用标准的CSS样式选择，如class和id。例如。

// Class 
$('.my-class') 
// Id 
$('#my-id') 
// Element 
$('div')

而对于点击...

// You don't have to pass event, but it may be useful 
$('.my-class').click(function (event) { 
    /* Do something */ 
});

希望这有助于。还有一些Google搜索快速显示给你。 :)

谢谢，但我没有使用jquery我正在使用Java。 :( – user3493818

大声笑，我确实对Java和JQuery标签有点困惑，抱歉我不能帮助，希望你很快得到解决方案。 – JakeSidSmith

尝试使用下一个查询(//h2[@class='blog-post-title'])[position()=1]其中position()指定确切需要抓取的元素的数量。

通过指定索引

By.xpath("(//h2[@class='blog-post-title']/a)[3]")
