如何通过Selenium使用xpath定位元素

代码试用：

By.xpath("//*[contains(@class,'a-size-mini a-spacing-none a-color-base s-line-clamp-2') and contains(text(), \"Men's Downshifter 9 Training Shoes\")]"));

HTML：

 <h2 class="a-size-mini a-spacing-none a-color-base s-line-clamp-2"> <a class="a-link-normal a-text-normal" href="/Nike-Downshifter-Running-Shoes-Anthracite/dp/B07H84PMGS/ref=sr_1_3?dchild=1&amp;keywords=NIKE+TRAINERS+FOR+MEN&amp;qid=1578766779&amp;sr=8-3"> <span class="a-size-base-plus a-color-base a-text-normal">Men's Downshifter 9 Training Shoes</span> </a> </h2>

关闭]

By.xpath("//*[contains(@class,'a-size-mini a-spacing-none a-color-base s-line-clamp-2') and contains(text(), \"Men's Downshifter 9 Training Shoes\")]]"));

备择方案：

1. //h2[.='Men's Downshifter 9 Training Shoes']
2. //span[.='Men's Downshifter 9 Training Shoes']/ancestor::h2[1]
3. //h2[./a[.='Men's Downshifter 9 Training Shoes']]

Answer 2

要定位元素，您可以使用以下基于xpath的定位器策略之一：

• 使用xpath和text() ：

   By.xpath("//span[text()=\\"Men's Downshifter 9 Training Shoes\\"]"));

• 使用xpath和contains() ：

   By.xpath("//span[@class='a-size-base-plus a-color-base a-text-normal' and contains(., 's Downshifter 9 Training Shoes')]"));

• 使用xpath和父<a>标签：

   By.xpath("//a[@class='a-link-normal a-text-normal' and starts-with(@href, '/Nike-Downshifter-Running-Shoes-Anthracite/dp/')]/span[@class='a-size-base-plus a-color-base a-text-normal' and contains(., 'Downshifter 9 Training Shoes')]"));
