When automating a website with Selenium C#, I encountered a NoSuchElementException when trying to click an element using a CSS selector. However, the issue was resolved when using xpath instead. Can someone shed light on why this discrepancy between CSS and xpath selectors?
Xpath value:
//*[@id="primary-navigation"]/ul/li[2]/aCSS Selector value:
#primary-navigation > ul > li:nth-child(2) > aUsing xpaths, the expression li[2] will target the second li element in the document.
On the other hand, utilizing CSS, li:nth-child(2) selects the li element that is the second child of its parent.
Consider this scenario:
<ul>
<p> something </p>
<li> this will be returned </li>
</ul>
In this case, the xpath li[2] would not match anything since there is only one li element present.
However, using css with li:nth-child(2), the li element will be successfully targeted as it is the second child of the parent ul element.
Therefore, it's essential to understand that while both selectors are functioning correctly, direct translation between xpath and css selectors may not always be possible or straightforward.
