Xpath @role or contains(@class)

[Nortier David]

Hello

 

In c#, I want to find elements that have either a given role, either a specific classname

 

I want to fins all alerts

 

The code :

• this.Driver.FindElements(By.XPath("//div[@role='alert' or contains(@class='alert')]")))

 

The error :

• invalid selector: Unable to locate an element with the xpath expression //div[@role='alert' or contains(@class='alert')] because of the following error:
• SyntaxError: Failed to execute 'evaluate' on 'Document': The string '//div[@role='alert' or contains(@class='alert')]' is not a valid XPath expression.
•   (Session info: chrome=101.0.4951.67)

 

 

What the fuck ? 😊

 

Thank you all !

 

 

  David

I think the correct xpath should be : 

("//div[@role='alert' or contains(@class, 'alert')]")))

Please try and let me know.

When using contains always you should use , instead of = sign. Use as 

• 
  
• this.Driver.FindElements(By.XPath("//div[@role='alert' or contains(@class,'alert')]")))

Thanks

One thing to be very careful with in XPath is the `contains` function. With the formulation shown in example in this thread, you have the potential for incorrect matches. Use this instead:

• this.Driver.FindElements(By.XPath("//div[@role='alert' or contains(concat(' ',@class,' '),' alert ')]")))

The key here is that we're ensuring that we only match the "alert" class precisely. Without concatenating spaces to the ends of the class value and matching " alert ", we could match elements with class values in which "alert" appears anywhere (e.g. - "unalerted").

This is why I prefer CSS selectors. These locators are specifically designed to match class specifiers:

• this.Driver.FindElements(By.CssSelector("div.alert, div[role='alert']")))

This CSS selector yields the same results, but is much more concise.

Nice ! Thanks
