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>

Answer 1

闭包]

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\")]]"));

替代方案：

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

要定位该元素，可以使用以下任一基于xpath的Locator Strategies

使用xpath和text()的

• ：

By.xpath(“//spantext()=\”男子Downshifter 9 Training Shoes\""));

• Using xpath By.xpath contains()：

类(“//span@class=‘a-size-base-plus a-color-base a-text-By.xpath’并包含(.，'s Downshifter 9 Training Shoes')"));

• Using xpath and parent <a> tag：

class(“//a@By.xpath=‘a-link-normal a-text-normal’并以(@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’)‘)开始；
