不是有效的 XPath 表达式

Question

I am trying to dowload a image in my web page with the xpath expression

Part of code

    with open('stiker.png', 'wb') as file:
            file.write(driver.find_element(By.XPATH,'//div[@class "_3IfUe"]/img[crossorigin = "anonymous"]').screenshot_as_png)

Part of page source i'm trying to dowload:

   <div class="_3IfUe">
       <img crossorigin="anonymous" src="blob:https://web.whatsapp.com/9a74a410-721b-4e8e-80f0-42d18288f480" 
       alt="" draggable="true" class="gndfcl4n p357zi0d ppled2lx ac2vgrno gfz4du6o r7fjleex g0rxnol2 ln8gz9je b9fczbqn i0jNr" style="visibility: visible;">
   </div>

Error

SyntaxError: Failed to execute 'evaluate' on 'Document': The string '//div[@class "_3IfUe"]/img[@crossorigin = "anonymous"]' is not a valid XPath expression.

Answer 1

As @John Gordon pointed out in his comment, you are missing a = between the @class and the value "_3IfUe" that you are trying to compare.

After fixing that, you need an @ before the crossorigin attribute name. Otherwise, it thinks you are looking for an element with that name.

It should be:

//div[@class = "_3IfUe"]/img[@crossorigin = "anonymous"]
