我点了很多页面,用一个简单的按钮去除了刮擦,甚至只是页面中的一个小故障。
这个问题似乎出现了很多,但我不确定如何解决它。从本质上讲,随着团队,赔率和其他事情的消失,它会获得带有链接的xpath:( //*[contains(@class, "sport-block") and .//div/div]//*[contains(@class, "purple-ar")])
。因为它应该但不是团队和可能造成无用的刮擦。
我最初使用的是CSS选择器,但我无法想象如何通过CSS的限制来实现这一点。
我想要的简单xpath:
//*[contains(@class, "sport-block") and .//div/div]//*[contains(@class, "purple-ar")]
问题仍然存在。
我对祖先和以前的人并不是很熟悉...但是像xpath这样的东西:
即://a/ancestor::div[contains(@class, 'xpath')]/preceding-sibling::div[contains(@class, 'xpath')]//a
为:
//a/ancestor::div[contains(@class, 'table-grid')]/preceding-sibling::span[contains(@class, 'sprite-icon arrow-icon arrow-right arrow-purple')]//a
可以解决(假设我可以让它工作)。

我有什么想法可以解决这个问题?感谢。
当前输出:
Steaua Bucharest Link for below
Celtic Link for below
Napoli Link for below
Lyon Link for below
所需:
Steaua Bucharest LINK FOR Steaua Bucharest
Celtic Link Celtic
Napoli Link for Napoli
Lyon Link for Lyon
我有什么想法可以解决这个问题?甚至缩小了做法?持续存在的问题。感谢。
答案 0 :(得分:4)
为了确保每个组的数据结构完好无损,我遍历它们并使用嵌套(或相对的?我不确定这里的术语)XPath来获取数据。可以通过在每个查询之前放置.
来使用相对XPath。
我也清理了一下:
如果这可以解决您的数据一致性问题,请告诉我。
